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.
