Threaded components, holes, and bolted connections are integral to a wide variety of engineering parts. The right type of threaded connection can make or break a 3D printed part. In this four part additive manufacturing series, we test a variety of 3D printing threads in the Markforged workshop.
In Part 1, we conduct thread testing on basic printed threads and tapped threads. Each thread type is evaluated using a set of key metrics:
Profile: How small a thread can be put in a part?
Pull strength: How strong the connection is with the thread if you try to pull a bolt from the threads embedded within.
Torque strength: If you have a thread and you’re screwing a bolt into it, will it fail if the bolt is tightened down too hard, or if you’re embedding a nut into a cavity, how much torque can the cavity handle it handle before the nut slips?
Installation - Design and work needed for placement.
Wear and Lifetime - Durability over time.
