What we take on

What to send

Prototyping works best when the print settings match the question you are trying to answer.

How the price is worked out

Draft quality at 0.30 mm layers prints considerably faster and comes out noticeably cheaper, which is the right setting for early fit checks. Save fine quality for the round you show to other people. If you are ordering several iterations of the same part, send them together and pay the handling fee once.

Where this works well

  • Checking whether parts physically fit together
  • Feeling how something sits in the hand
  • Catching the obvious mistake before it becomes an expensive one

Where it doesn’t

  • Predicting how a moulded version will behave — different process, different properties
  • Surface finish testing for a cosmetic end product
  • Fatigue and long-term load testing

Getting more out of each round

The temptation is to change five things at once and print. When the result is wrong you then have no idea which change caused it. Change one dimension per iteration where you can, and where you cannot, print two or three variants in the same order — different clearances on the same part, say — and test them side by side. That costs a few pounds more and saves a week of posting parts back and forth.

Questions people ask about this

Can I get it faster than 2–3 days?

Sometimes. Ask before ordering rather than after — if the machines have a gap and the part is small, we can often bring it forward. We would rather say no than promise and miss.

Should I print at fine quality?

Not for early rounds. Fine quality takes roughly twice as long as draft for the same part and tells you nothing extra about whether something fits.
