3D printing is a process to create physical, three-dimensional objects from digital models.

Wikipedia has more informations on the history of 3D printing and the available technologies; this article is concerned with hobbist accessible ones that can be used with software in Debian.

Hardware

Hardware support under Free operating systems tends to be excellent for models developed by the makers community and non-existent for models sold via traditional channels.

Fused deposition modeling (FDM)

Some models supported by Debian include:

Software

Going from an idea to a finished object requires a number of distinct steps that are usually done from distinct programs.

Design

Any software that is able to manipulate 3D shapes can be used to create a model for printing; ideally it should be able to export an .stl file, but there are conversion tools for many other formats.

Model conversion and fixing

Some models may require conversion from other formats to .stl, or they may have geometry problems that could prevent a successful print; programs such as meshlab are useful to prepare the model for printing.

Slicing

The next step is slicing, i.e. cutting a 3d model (usually described by triangles) in a number of slices a fraction of mm high and describing each slice with the path that a printing head should follow to print the slice.

This step generates a .gcode file based on settings that are usually specific for the printer (printing plate size, number of printing heads, etc.), filament used (printing temperature, etc.) and model (layer height, speeds, supports for overhangs and many more).

Printer control

The last step involves actually sending data to the printer: this is done with a program that is usually also able to give simple commands for mainteinance such as moving the plate/printing head/filament or setting the temperature.

Many printer control programs also include an interface to a slicing program, usually one of the ones mentioned above.
