Threaded inserts are great for melting into FDM prints with a soldering iron. The process isn’t so simple for resin prints, since they don’t generally soften with heat. Off course, you can also print ...

This article was updated May 25, 2023. It was originally published Nov. 17, 2009. To put hard, durable threaded holes in plastics, engineers often specify threaded metal inserts that will securely ...

If you want to make serious assemblies out of 3D printed parts, you’ll eventually need to deal with threading. The easiest way is to make a nut trap that you can either insert a standard nut into ...

Historically, the threading of holes has been a fairly straightforward operation, usually performed close to the end of a part’s machining. Once the holes had been drilled, thread taps of the ...

We have all done it, overtightened a bolt and blown out the threads. When a bolt starts to tighten up and then go suddenly loose, you know that the threads are toast and now you have a problem.

Single Profile Thread Mills (SPTM) thread small holes with coarse threads in tough materials — a common mold and valve-industry problem. The tools have a solid-carbide-micrograin substrate with a ...

Plastic parts and assemblies are becoming more common as engineers work to reduce costs and weight in their designs. But plastics often aren’t strong enough to support fasteners such as screws or ...
