Slicing 3D Models
In this chapter, we will discuss how to generate the G-code for your Artifex 2 3D Printer
from a 3D model of your choice, either downloaded from an online 3D model repository or
created by your own. Discussion in this chapter is based on printing with PLA filaments.
Printing with ABS filaments will be covered in the next Chapter.
3.1
Getting 3D models
3.1.1
Creating your own 3D models
A 3D model can be created by various 3D modeling software. Some examples include:
Free 3D modeling software:
•
OpenSCAD: http://www.openscad.org
•
Blender: http://www.blender.org
•
SketchUp: http://www.sketchup.com
•
FreeCAD: http://www.freecadweb.org
•
Tinkercad: http://www.tinkercad.com
Commercial 3D modeling software:
•
SolidWorks: http://www.solidworks.com
•
AutoCAD: http://www.autodesk.com
•
Alibre (now Geomagic
R
): http://www.alibre.com
3.1.2
Downloading 3D models from online repositories
You can also download 3D models from online repositories, for example,
•
Thingiverse: http://www.thingiverse.com
•
GrabCAD: http://www.grabcad.com
A 3D model can be saved in different file formats. The STereoLithography (STL) format
is a format widely used for 3D printing. In the following discussion, it is assumed that the
3D model you created or downloaded is already saved in a STL file format.
