INSERTS
Threaded brass inserts, heat-set into every part
Printed plastic threads wear out fast. Heat-set brass inserts give your part durable, reusable threads that hold up to repeated assembly and disassembly.
WATCH HOW IT WORKS
Heat-set insertion, visualized
A heated tip melts the insert's knurled brass body into a printed mounting hole, as the brass cools, it locks permanently into the surrounding plastic.
THE PROCESS
From printed hole to permanent thread
Pilot hole printed
The part is printed with a pre-sized mounting boss and pilot hole, slightly smaller than the insert's outer diameter.
Insert heated
A heated tip, sized to match the insert, brings the brass insert to installation temperature.
Pressed into the hole
The hot insert is pressed straight down into the pilot hole. The heat melts the surrounding plastic just enough for the insert's knurled exterior to sink in.
Cooled & locked
As the plastic cools and re-solidifies around the knurled brass body, the insert is mechanically locked in place, leaving a durable, reusable metal thread.
WHY BRASS INSERTS
Threads that survive real use
Reusable

Withstands repeated assembly and disassembly without stripping, unlike threads cut directly into printed plastic.
Stronger Joint

The knurled exterior locks mechanically into the plastic, holding far more torque and pull-out force than a plastic thread alone.
Standard Hardware

Compatible with standard metric screws and bolts, no special fasteners required for assembly or service.
