  1. Returned items must have all original packaging and be unused.
  2. Opened filament is not returnable
  3. Shipping costs are nonrefundable. 
  4. Buyer is responsible for return shipping. You may use one of our easy return labels, and the cost of return postage will be deducted from your refund.
  5. We highly recommend shipping insurance and tracking when returning an item, especially for higher dollar items, such as 3D printers. Partsbuilt 3D will not be responsible for return items lost or damaged in shipping.
  6. 3D Printers, cabinets, the PolyBox and PolySher are subject to a restocking charge of up to 20%. We do not charge a restocking charge on anything else.
