Brass thread inserts are a great way to create strong, reusable threads in plastic parts—including those made with 3D printing. Once pressed into the material, they create a connection that is significantly more resistant to tearing than a traditional plastic thread.
How to properly embed a thread insert into plastic
1. Preparing the hole in the model
Create a hole with the same diameter as the outer dimension of the threaded insert.
For example: if the insert has a diameter of 4.0 mm, the hole should also be 4.0 mm.
This dimension will ensure that the insert fits tightly after heating and that the plastic flows evenly around it.
2. Setting the soldering iron temperature
Use a soldering iron and set the temperature between 150–200 °C depending on the material used:
- PLA: approximately 160 °C
- PETG: around 180 °C
- ABS / ASA: about 200 °C
3. Inserting the insert
Place the insert over the hole and gently press it with the tip of the soldering iron.
Once the insert is heated, it will slowly sink into the plastic.
After complete embedding, remove the soldering iron and allow the joint to cool.
4. Checking the result
After cooling, make sure that the insert is flush with the surface of the part.
The thread is then immediately ready for use.
