Why us

A manufacturing partner — not just a marketplace.

Most “instant quote” platforms route your file to an anonymous shop and hope it comes back right. We design our own machines, qualify every system we print on, and put a named engineer on every part — so quality and IP stay accountable to us.

How it works

Two ways to order.

Order online in minutes, or get an engineer on the phone first — either way the same team and the same QC standard carry your part through.

Fastest · self-serve

Order online

Most orders never need a call — upload, price, order.

  1. 1
    Upload & get an instant price. A standard mutual NDA is applied automatically before any file review.
  2. 2
    Place your order online. A free engineer DfAM check runs in parallel — we flag anything before printing.
  3. 3
    We print, QA & ship. On our AO Metal or qualified partner systems, with a QA report — 2–7 days.

Talk to an engineer

For tricky geometry, custom alloys or strict programs — get it right the first time.

  1. 1
    Call us, or request a callback. We sign a custom NDA if your program needs one.
  2. 2
    An engineer reviews your part and sends a firm, optimized quote — with DfAM suggestions to de-risk the build.
  3. 3
    Approve by web link or P.O. — into production on the same QC standard.

★ The Additive Plus network

One network.
More capacity, same standard.

We print on our own machines and on a qualified network of systems we've installed and service at customer sites — so you get more capacity, built-in redundancy, and production closer to you. Every node is held to one QC standard: AS9100 and ISO 13485 partner-aligned, with COA and parameters in every order.

Jobs in flightmany in · one spec · shipped everywhere
More capacity, faster

Overflow routes across the network, so urgent jobs don't sit in one queue.

One QC standard everywhere

We install, qualify and service every networked machine — a part printed at any node meets our spec.

Buy a printer, join the network

Purchase a system from us and you're in: overflow capacity, shared print parameters, priority service.

Run your own machine? Become a network partner.

Put your printer to work between your own jobs — earn from overflow orders we route to you, with shared print parameters, priority service and our QC standard.
