Creation[edit | edit source]

Manual[edit | edit source]

It is possible to design a 3D model from the ground up for 3D printing using standard 3D software.

3D Scanning[edit | edit source]

3D Scanning through techniques such as photogrammetry can be used to duplicate real world objects.[1]

Editing[edit | edit source]

Some models, such as those created by 3D scanning, require cleanup before they can be printed.[2]

3D models on a computer can represent things that are impossible to recreate in reality. Thus for a model to be 3D printable, it must represent an actual object, without errors in an object that would cause the interior of the model to not be watertight.[3]

File Formats[edit | edit source]

STL[edit | edit source]

A 3D Benchy model in .stl format.

.stl has become a defacto standard for many 3D printer slicer programs.[4][5]

3MF[edit | edit source]

3MF is an open source format that offers a number of improvements over .stl, such as being more error resistant and including color information.[6][7]
