Frequently Asked Questions - 3DEF

It's the digital file that faithfully represents your part in three dimensions. It's what we call a digital twin. What's in the digital model will be replicated (or needs to be replicated) in the physical part or equipment. It contains all the measurements, shapes, and details necessary for 3D printing or manufacturing. Everything that can be created, modified, tested, and observed, in all aspects, is done in the 3D model, because all changes are possible and less complex than in a physical component or piece of equipment. The 3D model can be modified at any time, even after prototyping the physical part, to adjust components, fittings, and functions. If you want more information, contact us.

3D printers only understand digital language. The model goes through software that defines the printer's movements and timing, usually by writing an alphanumeric code called G-code. The slicer generates the G-code according to the model's geometry and the necessary printing parameters. Without a correct 3D model, good slicing and consequently, a good print are impossible. A good model avoids errors, wasted material, and rework. If you have further questions, continue consulting our FAQ or contact us.

The file extension is the letters that appear after the period in the file name. Example: my_piece.stl → the extension is .stl. There are native extensions for each CAD software, which are not usually used by slicers. Pure CAD extensions are not suitable for slicing. For example, extensions .DWG, .DXF, .DGN, .SLDPRT are not opened in all slicers and are therefore often useless. The extension is just a "label" that tells the computer: "this file is of such and such type". A good 3D model for printing almost always needs to be in STL or STEP format .If you have any questions, please contact us.

Slicer software is the program that transforms your 3D model into instructions that the printer understands.It is one of the most important steps in the 3D printing process.How it works in simple terms:You have a 3D file (e.g., .STL or .STEP)The slicer "cuts" this model into very thin layers (usually 0.1 mm to 0.3 mm).It calculates everything: speed, temperature, filling, supports, etc.It generates a file called G-code — which is like a "recipe" that the printer follows layer by layer.Simple analogy:It's like having an entire 3D design and needing to explain to the printer how to build it layer by layer, like a cake. Important summary:Without the slicer, the printer doesn't know how to print your template.A good slicer makes a big difference in the quality, time, and quantity of material used. This applies to all types of printing that use layer-by-layer printing, whether FDM, UV resin printers, SLA, SLS, and others.At 3DEF, we professionally configure the slicer for each piece, ensuring the best possible result.Contact us

STL is a simple mesh format (triangulated surfaces). STL files represent the 3D model in a peculiar way: dividing the entire surface of the object into thousands (or millions) of small triangles.This division is called a triangular mesh or triangulated mesh.Simple explanation:Imagine you want to cover a soccer ball with small pieces of paper. The easiest and most stable way to do this is by using triangles.The STL file does exactly that with your 3D model: it covers the entire surface with triangles.Each triangle has 3 vertices (points) and one face (the surface of the triangle).The more triangles there are, the smoother and more detailed the surface becomes (but the file size increases).The fewer triangles, the more "square" or "faceted" the model becomes.Visual example:A perfect sphere requires thousands of small triangles to become round.A simple cube → needs only 12 triangles (2 triangles per face).It does not store technical information (exact measurements, radii, tolerances).Difficult to edit afterwards (it's like a "sculpture" made of triangles, not a technical drawing).It can have flaws (inverted triangles, holes, overlaps) if the model is poorly exported. STEP is a precise technical format, maintains exact measurements, and is ideal for engineering and post-editing. STEP (or .STP) is considered the best format for most professional 3D modeling applications. Here's why:Mathematical PrecisionSTEP stores precise geometric information (radii, angles, distances, perfect curved surfaces).STL transforms everything into triangles (approximate mesh). The more curves the part has, the more precision STL loses.Easy to EditIn STEP you can easily change measurements, add holes, change thicknesses, or make technical adjustments. In STL it is very difficult to edit, because it is just a "shell" of triangles.Maintains Technical InformationSTEP may contain:Dimensional tolerancesMaterialsAssembly hierarchy (if it's a set of parts)Model construction historyBest for Professional ManufacturingCompanies, industries, and engineers prefer STEP because it is the universal standard for exchanging technical files (used in SolidWorks, Fusion 360, Inventor, Catia, etc.).Fewer Printing ProblemsWith STP we obtain a much cleaner file, without flaws, holes or bad triangulation. Talk to us.

Some are famous, but very slow and with a very steep learning curve. Others are much more expensive, as they offer greater versatility in modeling, great conversion capabilities, and parameter analysis. Among the best known, and this doesn't mean they are the best, are: SolidWorks, Fusion 360, Catia, Solid Edge, Microstation, FreeCAD, AutoCAD, 3D Studio, Inventor, Rhino 3D, Blender, and many others. Of those mentioned above, some are industry standards, others are nowhere near them. But the truth is that the best software for you is the one that suits your needs. Here at 3DEF we have our standards, with high-end software, because we model parts that require digital testing before they even go to printing and prototyping.

Generally, the problem stems from incorrect modeling, incorrect export, poor mesh quality, low-quality software, computers with low processing capacity, and lack of verification. Models made by amateurs or AI often have holes, inverted faces, or inconsistent thicknesses. Modeling goes far beyond simply giving shape to an object. Talk to us.

If your model was acquired from a modeler who didn't consider professional extensions, the problem is quite significant. STL files, for example, are terrible for editing and often require rebuilding the model.When a model allows for correction, we correct it and generate a STEP extension, which is a professional standard accepted worldwide. Files originating from incorrect 3D scanning or from equipment that is not industrial-grade generally carry uncorrectable flaws.

Here at 3DEF, we focus on precision, functionality, and genuine manufacturing. Talk to us.

It's possible in many cases, but it requires redesigning the part. We calculate the resistance, alter the geometry, add ribs, and define the correct polymer (Nylon CF, Polycarbonate, PEEK, etc.) so that the part performs equally to or better than the original metal. Many factors are involved in a technical decision. However, all parts and components that can be replaced by others manufactured through additive manufacturing are being replaced due to their versatility and the possibility of rapid replacement. Talk to us.

Inserts (whether cavities or cores) are replaceable parts of the mold holder. Traditionally, they are machined using CNC or EDM. Today, many are being replaced or supplemented by inserts manufactured using additive manufacturing (3D metal printing).How are metal 3D printed hair extensions manufactured?Optimized ProjectThe insert is redesigned in CAD taking into account the advantages of additive manufacturing: conformal cooling channels (which follow the shape of the part), lightweight internal structures (lattice), improved material flow and air escape.3D Printing in MetalMain technology: SLM (Selective Laser Melting) or DMLS (Direct Metal Laser Sintering).Material: 316L Stainless Steel, 17-4PH, AlSi10Mg Aluminum or Maraging Steel.The laser melts the metal powder layer by layer (usually 20 to 50 microns per layer).Heat Treatment and Post-ProcessingRelief of thermal stresses.Precision machining of contact faces and sealing surfaces.Polishing or texturing the cavity surface.Surface treatments (nitriding, DLC coating, etc.) when necessary.Integration into the MoldThe printed prosthetic part is mounted onto the base mold (usually conventionally machined) and tested in production.Advantages compared to traditionally machined inserts:Conformal cooling channels → Reduce cycle time by up to 30-50%.Complex geometries that are impossible or very expensive to machine.Lower weight (optimized internal structures).Shorter manufacturing time for complex parts.Longer service life in some cases (better heat distribution and less thermal deformation).Easier to repair or modify.Limitations:Higher initial cost for very small print runs.Advanced design knowledge is required to take advantage of the benefits.At 3DEF, we work with partners specializing in metal 3D printing, handling all aspects of design, engineering, and manufacturing follow-up. If you need to replace or create a new mold, we can analyze your case and recommend the best solution (traditional machining, hybrid machining, or fully metal printing). Contact us.

We perform reverse engineering and optimized redesign. We analyze the original part, identify critical points, and adapt the design for additive manufacturing, often resulting in a lighter part with improved performance. Contact us.

Soft molds are temporary molds used to produce small series of parts. They can be produced in PU, silicone, or two-component resin. We develop the 3D model, the model, produce the soft mold and functional parts on a small scale for testing, prototyping, or even for intensive use, if feasible. Contact us if you need parts in small batches.

Is it always necessary to use aluminum? Not always.Currently, with the wide variety of engineering polymers available, we can analyze with much greater precision whether a part really needs to be made of aluminum.Many parts are produced in aluminum for convenience—ease of machining, designer familiarity, or lack of lightweight options in the past. However, many of these parts do not require the characteristics of aluminum and could be replaced by simpler, lighter, and more economical polymers without sacrificing performance.Other components truly require the specific properties of aluminum (thermal conductivity, high rigidity, heat dissipation, etc.), and in these cases, replacement may not be recommended or may require a high-performance polymer.Therefore, the choice of the ideal material depends directly on the function of the part, the working conditions (temperature, load, impact, chemical contact, etc.) and the project objectives (weight, cost, durability).It's not always necessary to use an expensive engineering polymer to replace aluminum. Often, a good quality PETG, Nylon, ABS, or ASA will do the job with excellent results.Here at 3DEF, we help you conduct this analysis using technical criteria: we evaluate what is most functional, durable, and economical for your specific case. Talk to us.

Yes, it's one of our specialties. We create functional prototypes, perform fit tests, create prototypes for validation, and even produce pre-series production. We can also produce small batches, as well as print on specific materials for certification testing. Contact us.

Yes. We deliver complete assembled prototypes, with mechanical components, wiring, circuit boards, and functional testing upon request. We don't just focus on mechanical development; we are a hub for multidisciplinary solutions. Talk to us.

Here at 3DEF, our engineers have over 38 years of experience in traditional manufacturing (machining, casting, CNC) and over 12 years in additive manufacturing. We come from the era of Nardini and Imor lathes, Lagun Infreza machines, Semeraro injection molding machines, Charmilis EDM machines, Romi machining centers, and Bambozzi and ESAB welding equipment. We're from the time when those who studied at SENAI were CP (only the old-timers know what that is). Today, we combine the old and the new, reinventing manufacturing, but we continue to have fun, because those who enjoy the smell of soluble oil and hot plastic in injection molding machines never leave this profession. This combination is rare and very valuable. Talk to us.

Yes. We help with everything from choosing printers to developing optimized parts, training, and reducing costs associated with spare parts inventory. Contact us.

We'll take care of it for you. With 38 years of experience in product design, we transform your description or reference into a professional 3D model. It's one of our most requested services. And, to be honest, we've been in your shoes so many times that we know how difficult it can be. That's why we want to make it easier for those who need it. Talk to us.

It depends on the case. If the goal is only laboratory validation and the geometry allows it, TPU printing is better. If it's an item intended for use, with a complex geometry that prevents gravity molding in a soft mold, TPU printing is also more recommended. If it's a part that requires finishing, needs to be produced in small quantities, and the geometry allows it, developing the model, the soft mold, and casting the part with two-component PU resin can be much more advantageous. We evaluate your project and recommend the best option. Contact us.

Yes, we produce silicone, resin, or nylon molds for casting flexible parts. Contact us.

Yes, it depends on the technology, equipment, and the professional's experience. There are specific techniques and methods . 3D Scanning: Linear Technology vs. Cross-Technology. When we physically scan a part to create a digital 3D model, the way the scanner captures the data makes a big difference in the quality and quantity of final details.1. Linear Technology (or Single-Line Scanning)The scanner makes a single pass in one direction (usually front to back or top to bottom).Captures data in a straight line or at a single angle.Advantages:FasterGood for simple, flat pieces.Disadvantages:It loses a lot of detail in side areas, backgrounds, holes, recesses, and sloping surfaces.This creates more "holes" and areas lacking information in the final model.Lower precision in complex geometries.2. Cross-Angle Technology (Multi-angle or Multi-passage)The scanner captures the part from several different angles, making cross-sectional passes (horizontal + vertical + diagonal).Multiple scans are performed with the part rotated or with the scanner moving in different directions.Advantages:It captures much more detail, including in difficult areas (holes, threads, recesses, thin edges and curved surfaces).It drastically reduces data gaps and areas without data.It generates a much denser and more complete point cloud.Final result with much greater definition and geometric precision.Disadvantages:It takes longer (usually 2 to 5 times longer than linear).It requires more processing power on the computer.In addition to scanning technology, we place small circular stickers (also called targets or markers) at strategic points on the garment.Why do we use these stickers?They serve as fixed reference points that the software easily recognizes.They allow the scanner to precisely align all scans taken from different angles.They drastically reduce alignment errors and distortions in the final model.They significantly improve the dimensional accuracy of the scanned part (they can achieve tolerances of 0.05 mm to 0.1 mm).They facilitate the merging of point clouds coming from different positions.Without these markers, the software has to "guess" how the scans fit together, which can lead to minor distortions or inaccuracies. With the stickers, the result is much more faithful to the actual geometry of the part.At 3DEF, we preferentially use cross-scan technology in most scans, especially when the client needs high definition, tight tolerances, or faithful reproduction of details.We only use the linear method for very simple parts or when the deadline is extremely tight. After cross-scanning, we still perform a mesh cleaning and optimization step to deliver the best possible file (STL or STEP). Contact us.

There are 7 main categories of 3D printing, according to the international standard ISO/ASTM.However, in practice, the most commonly used ones — especially for inventors, prototypes, and small businesses — are the following:1. FDM – Fused Deposition Modeling (the most popular)It works by extruding molten plastic filament layer by layer.Advantages: Inexpensive, durable and functional parts, wide variety of materials (PLA, PETG, Nylon, TPU, etc.).Disadvantages: Finish with visible lines.Best for: Technical, functional, mechanical parts and rugged prototypes.2. SLA / DLP / LCD – Resin Printing (photopolymerization)It uses UV light (laser or projector) to harden liquid resin.Advantages: Excellent detail, smooth surfaces, high precision.Disadvantages: More fragile parts, require post-processing (washing and curing).Best for: Detailed models, jewelry, miniatures, aesthetic pieces, and high-end prototypes.3. SLS – Selective Laser SinteringIt uses a laser to fuse polymer or metal powder.Advantages: No support needed, very strong parts, complex geometries.Disadvantages: More expensive and usually industrial.Best for: Strong, functional parts, small-batch production, and parts without supports.4. MJF – Multi Jet Fusion (from HP)Similar to SLS, but uses ink jets + a fusing agent in the powder.Advantages: Fast, good quality and uniform finish.Best for: Industrial production of durable parts.5. Metal Printing (SLM / DMLS / EBM)It melts metal powder using a laser or electron beam.Advantages: High-performance metal parts (aluminum, titanium, steel).Best for: Aerospace, medical, automotive, and tooling industries.Other important technologies:Binder Jetting → Sprays "resin" onto powder (good for sand, ceramics, and metal).Material Jetting (PolyJet) → Sprays droplets of material like a color printer (multi-material and colors).DED (Direct Energy Deposition) → Used for repairs on large metal parts.There are other technologies, but we can address that topic when we make our explanatory videos. Talk to us.

PLA, ABS, and PETG are the most commonly used materials for prototypes and standard parts. PLA offers a wider variety of colors, as its function is purely aesthetic, since the material itself lacks mechanical properties such as impact and heat resistance. PETG is recommended for parts that require more mechanical resistance, such as resistance to drops. ABS is a polymer recognized for its mechanical and thermal characteristics, but it requires more care from the user as it deforms more easily during the printing process. Regardless of the material type, quality and origin are crucial for successful printing. Materials purchased from marketplaces, which are not responsible for what they are selling, are always susceptible to being copies. Be very careful. To learn more, contact us.

The polymers considered "engineering" available at the time of writing this response are: Engineering PETG, Nylon (Polyamide and Polyimide - PA6 / PA12), PC (Polycarbonate), Polymer blend of PC + ABS (Polycarbonate + Acrylonitrile Butadiene and Styrene), Nylon + CF (Polyamide with Carbon Fiber), ASA (Acrylonitrile Styrene Acrylate), PEEK (Polyetheretherketone).TPU (Thermoplastic polyurethane)** PEI (Polyethermide) - ULTEM PPS (Polyphenylene sulfide) There are advanced Polypropylene (PP) formulations developed specifically for orthopedic rehabilitation components.Furthermore, there are special filaments made with polytetrafluoroethylene (PTFE) , better known as Teflon , which are used in experimental applications requiring very high chemical resistance and a low coefficient of friction. However, these materials are still relatively rare and expensive in the Brazilian market.Important to differentiate: The acronym TPU specifically refers to Thermoplastic Polyurethane in filament form for 3D printing. This designation is necessary to distinguish it from two-component polyurethane (mixture of isocyanate + polyol), which also forms an elastomer, but cures cold (without heating) and is used in molds and casting.

When we replace a traditional material (such as aluminum or steel) with a 3D-printed polymer, simply using the same design is not enough. The part needs to be redesigned for two main reasons:1. Each material has different mechanical properties.Each material has its own strength, stiffness, flexibility, and density.A part made of nylon with carbon fiber, for example, does not support load in the same way as a part made of aluminum or steel. Therefore, it is often necessary to alter the geometry (wall thickness, reinforcing ribs, internal shape, etc.) so that the part performs as expected.2. Anisotropy of 3D printing3D printed parts are anisotropic, meaning their mechanical strength varies depending on the direction of the applied force. They are stronger in the direction of the layers and weaker between the layers.Materials like steel and aluminum are isotropic: they exhibit virtually equal strength in all directions.This difference requires technical knowledge to correctly guide the design and orientation of the print.Summary:Replacing traditional materials with 3D printed parts is not simply a matter of "swapping the material." It requires re-engineering the part, calculating its strength, and expertise in additive manufacturing.Here at 3DEF, the phrase "I think it'll work" doesn't exist. We perform the calculations and redesign responsibly to ensure your part truly functions. Talk to us.

At 3DEF, we have a robust and well-equipped internal structure to print parts up to 450 × 450 × 470 mm in engineering polymers using FDM technology.This capability meets the needs of the vast majority of technical projects, prototypes, and functional parts with excellent quality and precision.For projects requiring larger scale, we rely on a consolidated and validated network of national and international partners.Through them, we can print parts with the following maximum sizes:Polymers (FDM / Pellets): up to 1200 × 1220 × 1220 mmSintered metals (3D metal printing): up to 800 × 800 × 600 mmWe have worked with these partners for years, employing rigorous quality control processes.We at 3DEF are responsible for the entire workflow: contacting the client, technical analysis of the project, choosing the best supplier, monitoring production, final quality control, and delivery.This means you have a single point of contact (us) from start to finish, with full technical and commercial responsibility.We have successfully served clients from various states in Brazil with large and demanding parts.If your part is large or requires special features (extreme strength, metal finish, high precision, etc.), send us your project and we will conduct a complete analysis and present the best solution — either with our in-house structure or with our specialized partners.Contact us

Yes, when well-designed and made with the right materials. We've already produced parts that work in machinery, automation, and industrial environments. Replacement parts for classic cars and motorcycles.Everything is related to assessing feasibility and the responsibility involved in designing and producing. 3D-printed animals and figurines are common. Technical parts require a much greater expertise. Talk to us.

We work directly with you from scratch. You explain the idea however you can (speaking, drawing, taking photos) and we work our way up until we can create the first 3D model. After that, we refine and fine-tune it until we reach the ideal model. Then, we move on to the functional technical model. It's important to remember that the 3D digital model is the digital twin of what the piece will be, and you don't need design software to visualize your models. The visualization software we use is free. Many inventors start their inventions exactly this way.

In the simplest way possible. Use everyday words, hand-drawn sketches, reference photos, or even examples of similar products. You explain the idea however you can (speaking, drawing, taking a photo), and we'll work our way up until we can develop the first 3D model.After that, we refine and fine-tune it until we reach the ideal model.Then we move on to the functional technical model.It's important to remember that the 3D digital model is a digital twin of what the piece will be, and you don't need design software to visualize your models.The visualization software we use is free.Many inventors begin their inventions exactly like this. We are used to translating inventors' ideas into technical models.

The 3D model viewers we use are free and available for download online. They allow you to view the model, rotate it, observe details, and even take measurements, without the need for design software. If you have freeware CAD software, you can use that too. It's very simple. Contact us and we'll guide you.

We recommend signing a Non-Disclosure Agreement (NDA) before sending more sensitive details. We only work with NDAs; no ideas are shared before at least one signed document is in place. It doesn't create any financial commitment, has no cost, and is a way to identify the parties involved in the exchange of information. We work with this frequently and fully respect the intellectual property of our clients, as we are also developers and understand the value of intellect in a product. For further clarification, please contact us.For information on patenting, see our answer about patents.

The best way to protect your idea is to act in stages, combining confidentiality, registration with the INPI (Brazilian National Institute of Industrial Property), and strategy. There is no 100% automatic protection, but following this path greatly reduces the risk of copying. Recommended step-by-step:Non-Disclosure Agreement (NDA) Before sending technical details or files to any company (including us), request or sign an NDA. It obligates the other party to maintain confidentiality. At 3DEF, we work with NDAs frequently and without problems.Industrial Design Registration (very important for products) Protects the external appearance of the product: shape, design, lines, contours, and aesthetics. It is faster and cheaper than a patent. It lasts up to 25 years. Ideal for protecting the "visual" aspect that differentiates your product in the market.Patent (Invention or Utility Model) Protects the technical/functional aspects of the invention (how it works, new technical solution). It requires novelty, inventive step, and industrial application. The process is longer (can take years) and requires very detailed descriptions. We recommend consulting a lawyer specializing in industrial property. NEVER, EVER, UNDER ANY CIRCUMSTANCES, hire one of those companies that advertise on the internet offering patents for less than the price of a cup of coffee a day. Patents are serious business! It's not something to be handled by someone without ENORMOUS experience in the field, with proven cases. NOTE: We are not a law firm specializing in patents; we have a firm that handles this for us, but you should choose your own, and trustworthy one.Trademark registration protects the name, logo, slogan, or combination thereof. It is also done at the INPI (National Institute of Industrial Property). It ensures that no one else can use your brand in the same segment.Product Dressing (or Trade Dress) is the protection of the overall visual appearance of a product, including its packaging and general presentation (colors, layout, style). In Brazil, it doesn't have a specific registration like in the US, but it is protected by Industrial Property Law against unfair competition and market confusion . Courts already recognize and punish copies that replicate the "complete visual appearance" of a product.Do not publish photos, videos, or details of your idea online before registering it (this may invalidate the patent due to lack of novelty).Always start with an NDA + Industrial Design (faster and more accessible for small inventors).For patents and trademarks, it is ideal to have a lawyer or consultancy specializing in IP (Industrial Property).At 3DEF, we help many inventors in this initial modeling and prototyping phase, always respecting confidentiality. WARNING: Patent offices never tell you that if a charlatan appears copying your idea, you will have to hire an army of lawyers to serve summonses, file lawsuits, and conduct search/seizure operations at the counterfeiters' establishments. Pay close attention to this detail: Patenting is cheap, fighting for your rights is another cost. To learn more, contact us.

Start with a functional prototype. We help from 3D modeling to printing the first prototype, testing, and adjustments. Many inventors we've worked with started with exactly this step. See our question: How do I transform an idea that's in my head into a 3D model? Answer: We work directly with you from scratch.You explain the idea however you can (speaking, drawing, taking a photo) and we'll work our way up until we can develop the first 3D model.After that, we refine and fine-tune it until we reach the ideal model.Then we move on to the functional technical model.It's important to remember that the 3D digital model is a digital twin of what the piece will be, and you don't need design software to visualize your models.The visualization software we use is free.Many inventors begin their inventions exactly like this. Contact us.

You've already found it.At 3DEF, we treat every inventor with genuine attention, respect, and without rushing.We know exactly what it's like to be on the other side. For many years, we were small inventors like you and faced the same difficulty: most companies didn't pay attention to us, they thought we lacked "technical knowledge" and barely explained the process. They didn't guide us and often treated us like amateurs.It was precisely because we experienced this frustration that we decided to change the game. After working for years developing projects for other companies, we realized we could do much more: help other inventors transform their ideas into reality in a professional and humane way.3DEF was born out of this real need — both ours and that of so many other inventors and small entrepreneurs who are going through the same situation.Today we no longer develop our own projects. We are dedicated to being the technical partner we wish we had had in the beginning: experienced designers, modelers, and manufacturers who understand the reality of those who are starting out. With over 38 years of experience in product design and manufacturing, we are able to translate ideas into functional prototypes with clarity, patience, and technical expertise.Here, you're not just another customer. You're an inventor who deserves to be heard and well-guided. Talk to us.

It's very simple and quick. Send a message via WhatsApp (11) 97744-0004 if you have a file (STL, STEP, photo, drawing, a doodle 🙂) or a description of what you need. We will contact you via WhatsApp, by phone, or we can even schedule a video conference (in more complex cases) to understand what you need and send you an estimate.

You can send anything that explains your idea. Photos of the piece, hand-drawn sketches, videos, or even a more or less detailed description (dimensions, function, desired material). The more information, the more accurate the quote will be. However, we understand that you won't always have all the necessary data, and our role is precisely to simplify things so you can get to where you need to be to obtain a cost estimate. It's normal that, in ideas and developments, there isn't something so detailed as to request a quote, and we understand that, because we've been in your shoes (many times 🙂). Talk to us.

It's very common for inventors and developers to start their ideas with sketches and then create a prototype with whatever they have. That's where great ideas and world-changing innovations are born. We've made many sketches of our ideas and many prototypes with what was available, trying to understand and explain them. We've been doing the same thing for over 38 years! 🙂You can send a photo or video of the handmade piece. If you prefer, we can schedule a video call or even a visit (in São Paulo) to better understand the details and functionalities you want. Contact us!

Yes, we provide preventative and corrective maintenance services at your home in São Paulo and Greater São Paulo. We service major brands (Creality and Bambu Lab). On-site diagnosis, transparent quotes, and fast repairs. Contact us.

At 3DEF you'll find what you're looking for. We've been working in printer maintenance for years and have a deep understanding of how printers work internally. Many customers come to us after having bad experiences with generic repair services.Contact us

Avoid risky transport, the risk of further damage, and wasted time. We perform a complete diagnostic in your environment, test the printer on-site, and deliver it back in working order before you leave. Plus, you don't need to disassemble or pack the machine. Contact us.
