Build Your Own 3D Printer — Intro to CAD: Design → Slice → Print
(session 3)
This workshop introduces parametric CAD for 3D printing. Students design a simple, functional part, export it to STL, slice it, and print it end-to-end—building a workflow they can repeat independently.
Through interactive lessons and hands-on activities, students will:
- Create sketches with constraints and dimensions, then extrude, fillet, and chamfer features.
- Apply print-oriented design: clearances/tolerances, hole sizing, overhang awareness.
- Export watertight STL files and perform quick “printability” checks in the slicer.
- Run a clean print using a short start-of-print checklist.
- Save an Onshape document they can iterate on after class.
- Reflect on how design choices affect print success, strength, and usability.
Grounded in Onshape’s beginner workflows and print-oriented design practices, this session builds confidence from idea to usable part.
