Summary

PETG and ASA are common choices for functional FDM parts. The right choice depends on environment.

  • PETG is a balanced default for many indoor technical parts.
  • ASA is usually stronger when UV and outdoor exposure matter.
  • Heat, chemicals, impact and expected lifetime should decide the material.

Process

From CAD to repeatable production

1

Send files

CAD, drawing, photo or a short functional description.

2

Technical review

We review printability, material, orientation and risk.

3

Production

The batch is produced with repeatable parameters.

4

Re-ordering

Approved parts can get an article ID for faster repeat orders.

Common questions

Answers that move the project forward

Can you recommend the right process?

Yes. Upload the file and requirements and we will tell you when FDM is a good fit and when another process is better.

Is FDM always the cheapest?

No. Price depends on geometry, quantity, material and quality requirements.

Can the same design move to another process later?

Often yes, but DFM rules differ. Early review helps avoid unnecessary redesign.
