PA6-CF — Carbon-fibre-filled polyamide 6

Use it for

• Robot arms, production jigs, parts that move with the machine
• Parts under continuous load, where PETG would eventually creep
• Clips and tabs that must keep their spring after repeated assembly

What it will not do

• Three times the price of PETG: only worth it if the load demands it
• Matt, slightly rough surface — not a cosmetic material
• Black only

What we have learned using it

A lot of enquiries come in asking for PA6-CF when PETG is more than enough. We say so: an over-specified part has never won anyone's loyalty.

Consider instead

• PETG — in most cases
• PC — if the constraint is mainly thermal
