Usage and Workflow

The general process for 3D printing is outlined below. Please see the individual printer pages for full details.

1. Convert 3D model to STL or download an STL file from online.
   • https://www.printables.com/
   • https://www.thingiverse.com/
   • etc
2. "Slice" the STL file to generate GCode (or resin printer file).
3. Prepare the printer
   • Load filament
   • Clean/level the bed
   • Change nozzles if needed
4. Send the GCode to the printer.
5. Monitor the printer until the print is completed.

3D Modeling/STL creation

We currently recommend SOLIDWORKS for Makers or Alibre Atom3D which are both available on the laser-room computer. Autodesk Fusion 360 offers a free license for hobbyist use].

Other options which are FOSS include:

• OpenSCAD uses a text-based scripting language to define a model, making it distinct from other CAD software. It is great for making parametric parts, where a user can easily modify critical dimensions.
• Antimony is another procedural modeling software, which uses an interconnected graph of nodes to define geometry (rather than plain text). It is no longer receiving updates.
• SolveSpace is a constraint-based, parametric CAD program. It has the advantage of having a more traditional CAD interface, but there is a bit of a learning curve; going through the tutorials on the program's website is highly recommended.
• FreeCAD is a constraint-based, parametric CAD program. Its interface is usually considered more difficult, but recent updates have improved the experience. It is a very powerful software with many built-in tools.
