Why Are Items on Clearance?

At MatterHackers, to bring you new and exciting products, we occasionally shift some of our quality stock to the Clearance section.

Reasons for Clearance Items:
  • New Product Versions: When manufacturers release updated versions of printers, CNC machines, filament, etc., the older versions typically go to Clearance.
  • Overstock: Items we have in excess are moved to Clearance to free up warehouse space.
  • Discontinuation: Discontinued product lines often end up in Clearance to expedite the sale of remaining stock.
  • Packaging Changes: When packaging updates occur, we shift the older packaged items to Clearance.
Clearance Does NOT Imply:
  • Poor Quality: Clearance items meet our rigorous quality standards and often brand new, unopened products.
  • Limited Support: You'll receive our excellent customer service for Clearance items. Note, all Clearance purchases are Final Sale and not covered by the MatterHackers Return Policy.
