Why threaded inserts?
Withstands many screw cycles
Metal on metal instead of a screw in plastic.
High pull-out force
The insert anchors firmly in the component.
Standard threads
Metric threads matching standard screws.
Delivered ready
You receive the part ready to install.
How it works
- Step 1
Design
The receiving hole is designed to match the insert – we are happy to take care of that.
- Step 2
Printing
The part is printed with a prepared hole.
- Step 3
Inserting
The insert is installed with heat and anchored.
- Step 4
Inspection
Seat and thread are inspected.
Which processes and materials?
| Process / material | Suitability | Note |
|---|---|---|
| FDM (PLA, PETG, ABS, ASA, PC, PA) | very good | classically inserted with heat |
| SLS · PA12 | very good | very good anchoring |
| SLA | good | rather pressed in or bonded |
| Metal | not necessary | cut threads directly |
Where it pays off
Notes
Printed thread or threaded insert?
Printed threads work – in SLS from about M6 – but wear when opened often. Metal threaded inserts are the robust solution: metal on metal instead of a screw in plastic, high pull-out forces and many screw cycles. In FDM parts we install them with heat; in SLS they anchor particularly well.
You don’t have to design the receiving hole yourself: simply mark where which thread should go and we adapt the model. M2 to M8 are typical; other sizes on request.
Key values
| Sizes | M2–M8, others on request |
|---|---|
| Wall around the insert | plan sufficient material |
| Printed alternative | SLS from approx. M6 |
| In SLA | rather pressed in or bonded |
FAQ about threaded inserts
Do I have to design the hole myself?
No. Simply mark where which thread should go – we adapt the model.
Do threaded inserts hold in 3D printed parts?
Yes, correctly designed they hold very well and withstand many screw cycles.
