Print Farm FAQ

What is the minimum?
50 spools a month, any mix of materials and colours, unlocks per-kg pricing and a farm account. Below that, the automatic 12 % discount at 4+ spools applies with no account.
Do you offer net terms?
Net 30 from the second order for registered US businesses at 50+ spools a month. First orders are prepaid by card, Shop Pay or PayPal.
Can I lock a colour batch?
Yes from 200 spools a month. We reserve a single extrusion batch for your colour so parts printed months apart match.
Do 3 kg and 5 kg spools work in an AMS?
No, they exceed the AMS diameter. Farms running AMS units order 1 kg spools; farms on external holders take 3 kg or 5 kg for fewer changeovers.
Where do orders ship from?
Our US warehouse, 2–5 business days by ground. Pallet orders ship freight with a quoted date.
