Cannot get threads to work on 3D printed parts

[phoenixfire425]

I have tried several different ways to make threads on my 3d model.  These will be printed @ .1mm layers. 

Every time i go to print them the thread bind up and will not go past the first or second thread.

The attached models are using the 'coolOrange' add on.

Any help would be awesome!  I have tried to get this to work with equal size shaft and holes, and larger hole.  Still no luck.

Print resolution is at .1mm layer height so I dont think thats an issue.

Welcome to the forum.

Without having opened up your parts, have you tried using a swept cut with a coil sketch as your path and a triangular shape representing the thread profile?

Stupid question time: does your printer have the precision required to generate the threads so they'll work at both limits?

Try chamfer both threads.

Try that on printed part and see if it helps.

You might need to increase clearance.  Right now you have 1 mm on diameter.  Try 1.5 and 2.

I know when we have threads printed into our parts we have the vendor add them in their software. I create the hole and tell them the thread specs. They are using HP Multi Jet Fusion printers but do not know what the software is they are using. Works outstanding though.

Hi! The only problem I am seeing is multiple solid bodies. Try using Combine command to join the threaded portion with the main body. It should work better.

Many thanks!
