Sometimes, when making a 3D printed object, plastic just isn’t enough. Probably the most common addition to our prints is the ubiquitous brass threaded inset, which has proven its worth time and again ...

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 ...

SI inserts from PennEngineering permanently install in plastic assemblies to provide durable and reusable metal threads for mating hardware and allow for repeated ...

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 ...
