Buying 3D Printing With a Purchase Order: A Guide for Procurement Teams

How to add 3D Services USA as a supplier: W-9, COI and capability statement, purchase orders and net terms, tax-exempt orders, CAGE and UEI.

The Short Answer

We accept purchase orders and invoice with net terms on approval (Net 30 or Net 60). We keep resale and tax-exempt certificates on file. We complete vendor onboarding with a W-9, a certificate of insurance, a capability statement and a vendor packet, sent within one business day of your vendor request. Our CAGE code is 9UTB8, our UEI is K14NULDTF4Y5, and we are registered in SAM.gov.

Documents for Your Vendor File

  • Form W-9, signed.
  • Certificate of insurance, summarizing our general liability coverage.
  • Capability statement: a one-page overview of our services, materials and tolerances.
  • Vendor packet: everything combined for your vendor management system.

Identifiers for Federal and Institutional Buyers

CAGE code 9UTB8 and UEI K14NULDTF4Y5, registered in SAM.gov. We confirm NAICS and NIGP codes for your file on request, so the codes in your system are the ones we have confirmed for you.

What to Put on the PO

These details let a PO go straight to production:

  • The quote number (it starts with Q-), so the PO matches a price you were shown.
  • Each part and its quantity, and the process and material for each.
  • The ship-to address and a contact who can receive the delivery.
  • Your billing or accounts payable contact.
  • The net terms you need, and whether the order is tax-exempt.

Universities and Research Labs

We work with universities and research labs on education and research pricing, grant-friendly documentation and net terms. Labs that order often can open a business account, with volume and repeat-order pricing and a dedicated point of contact.

Without a PO

A team that does not need a purchase order can pay by card at checkout. The order, the files and the parts are the same either way.
