3D Printed Threads – Model Them in Fusion 360 | Practical Prints #2

by

Learn how to create 3D Printable threads in Fusion 360. I’ll show you how to add clearances based on your 3D Printer’s tolerance. I’ll also discuss a tip that will make your plastic threads even stronger.

This is episode #2 of Practical Prints, a Youtube series were Kevin Kennedy demos all things related to designing for 3D printing in Fusion 360.

Frequently Asked Questions

Can you 3D print working threads and screws?

Yes, working threads can be 3D printed with proper settings. Layer height of 0.1mm or finer works best, with slower print speeds improving quality. CAD tools like FreeCAD’s Fasteners workbench help generate accurate thread geometries.

What are the best settings for 3D printing threads?

Use 0.1mm layer height, slow speeds (~10mm/s), and tune thread scaling parameters. Common starting points: screw scaling A0.990/B-0.050, nut scaling A1.030/B0.100. Always test print to calibrate for your printer and filament.
