Materials

Which material should you choose? A plain-English guide to every metal and plastic in our price calculator.

The short answer

If you are not sure, keep the first option in the calculator. It is chosen because it suits most parts: standard plastic (PETG) for 3D printing and aluminium 6061 for CNC machining. You can always ask us before ordering — we are happy to advise.

Below, each material is described in everyday words, with what it is good for and which process can make it. Material codes (such as 6061 or 304) are given in brackets for engineers.
