3D Printing: Software for Design and Slicing

There are two applications necessary to design and print 3D objects.

  • 3D Design: If you want to make your own custom 3D models to print.
  • Slicer: To slice a model into code that your printer can understand.

If everything you want is already on Thingiverse.com, you can skip the design software altogether and just download a slicer.

Slicing Software: Cura

Once you have a 3D model, you need to slice it. That means creating the G-Code instructions for the very dumb printer. Like. “Go here, then go there. Oh, now, go here. Over there now.”

Just make sure to install Cura and go through some sort of tutorial to see how to use the settings. Here’s a good guide by all3dp.

Can I use SketchUp?

For those of us who can quickly model in SketchUp, learning a new program may be undesirable.

Quick answer: Yes, you can use SketchUp (with the STL Exporter extension), but it will be well worth your time to learn AutoDesk Fusion 360 for the capability of doing parametric modeling.
