Should Threaded/Tapped Holes Have Support Material

If I'm designing a threaded/tapped hole, should I use support material? I will be printing so that the thread is perpendicular to the bed i.e. a nut sitting on the bed flat.

 

I have done a few of these and never needed support. I guess it would depend on how far the threads sticks out.

 

If you're at the point that you're thinking about printing supports, I would just change the hole to the size you'd need for tapping with an actual tap bit and tap the threads after printing the object.

If you're talking about external threads, same thing. Print the column at the external thread diameter and then thread it with a thread die after the fact.

Coarse threads tend to print well, but anything that would be fine-threaded I'd either print as described above or go for the press-in inserts/helicoils.

 

Ok, thanks for the suggestions. I agree that that probably is the best solution as the shrinkage of the part may make it unusable.
