Metric Thread in 2 Minutes - AutoDesk Inventor - Coil Command
Hi All,
This video is all about Metric Thread Basics for 3D Printing.
Metric threads are the most widely used screw thread standard in the world and are defined by ISO standards. Thread sizes are measured in millimeters, with a 60-degree thread profile.
The theoretical height (H) of a metric thread is approximately 0.866 times the pitch, based on the geometry of the 60-degree thread form.
H=0.866P
Metric threads are ideal for 3D printing because they are easy to model, print, and assemble. When designing threaded parts, a small clearance should be added to compensate for printing tolerances. A good practice is to offset the external thread profile by 0.05 mm to 0.10 mm, which helps ensure smooth assembly and reduces the chance of threads binding together after printing.
In this tutorial, we'll create a fully functional metric external thread.
Enjoy the video.
Cheers
