Custom 3D printing & design

From idea to object.

Pristine prints, made to order. Send us a part, a sketch or just a problem — we design it, print it in the right material, and get it to you fast.

Plate IHow it works

How a custom job actually runs

Send a file or describe the part, and you get a price before anything is printed. A ready-to-print file is printed in 3–5 business days, then it is on its way.

  1. Send the file

    Drop an STL, OBJ or 3MF into Print My STL and the page measures it in your browser. No model yet? Describe the part and we quote the design work.

  2. We price it before we print

    The price comes from the volume of the model itself — its walls, top and bottom layers, and the infill it needs — not from a size band. If a part needs heavy support or something the page could not see, we message you before printing — never a surprise charge afterwards.

  3. We print it here

    On our own machines in New Jersey, in whichever of the seventeen materials the job actually needs. Nothing is outsourced and nothing is warehoused.

  4. It ships

    Print-only jobs ship in three to five business days, tracked, worldwide; anything we have to model first gets its own timeline in the quote. One-day turnarounds have happened when a prototype was urgent.

Plate IIIMaterials

Seventeen materials, not one

Most print shops quote you in PLA and hope the part never gets warm. Pick the one the job actually needs — or tell us what it has to survive and we will pick it for you.

The workshop

This is where your part gets made

No print broker, no outsourcing, no middleman quoting you on machines they have never touched. Every Prinstey order — the skulls and the custom jobs alike — comes off this bench in Edison, New Jersey.

That matters more for custom work than for anything else. When a part needs a second attempt at a different orientation, or a wall thickness changed before it is worth printing at all, that happens the same day — by the same person you have been messaging.
