Prototyping & functional parts

From CAD file
to working part, printed to spec.

A small-batch print shop for engineers and product teams who need real tolerances, real materials, and a straight answer on turnaround — not a marketplace queue.

Prototype to small-batch

One machine, run dialed-in and dedicated to functional parts.

Every job runs on the same calibrated CoreXY setup — not a mixed fleet with inconsistent settings.

MACHINE / 01

CoreXY FDM

High-speed printing on a fully enclosed frame, tuned for accuracy rather than just top speed.

How a job moves from file to shipment.

Four steps, the same order every time — so you always know where a part is.

01

Upload & spec

Send your CAD file and specs through the quote form — material, quantity, deadline, and any critical tolerances.

02

DFM review & quote

We check the file for printability, flag any risk areas, and send back a fixed quote — usually same day.

03

Print & quality check

Parts are printed, measured against spec, and visually inspected before they're cleared to ship.

04

Shipping or local drop-off / pickup

Tracked shipping is available nationwide. We also offer local drop-off and pickup throughout the Greater Boston area.
