To do this, they will need a basic grasp of slicing software. Furthermore, 3D printer users need to know how to convert their digital models into machine-readable instructions in the form of G-code. 3D designers must therefore be realistic about the possibilities and limitations of the printing process. After all, not every 3D model is suitable for 3D printing: a perfectly rendered model of an airplane might look great on screen, but its protruding wings and ultra-fine propeller blades might be very difficult to extrude using molten plastic. However, knowing how to make a 3D model for printing requires more than just artistic talent.

Typically, users can choose between 2D or 3D design views. Some users make their own 3D designs by drawing and modifying geometric shapes on-screen, but models can also be algorithmically generated. CAD applications are powerful tools that allow for the creation of very complex 3D designs.

But 3D printers can only work with digital instructions.ģD models for printing are made using computer-aided design (CAD) software. Compare 3D printing to machining, for instance: machines like mills or lathes can either use computer numerical control (with a 3D model providing the instructions) or be operated manually, without any digital foundation at all.

This isn’t the case with all manufacturing processes.

Knowing how to make a 3D model for printing is very important, since there is no other way to create printed objects. The outcome of the print is a physical representation of the digital 3D model. Every print begins with a digital model designed using CAD software, which is then converted or “sliced” into instructions that can be understood by the 3D printer. 3D models are the foundation of 3D printing.
