What Our Customers Say
Real feedback from engineers, designers, and makers who trust us with their parts.
PrintForge turned our prototype around in 26 hours. The surface finish was better than we expected and the tolerances were dead-on. They are now our go-to for all functional parts.
We needed 200 custom brackets for a medical device trial. PrintForge handled the entire run, inspected every part, and shipped two days early. Flawless execution.
Great communication and fair pricing. I have used three other 3D printing services and PrintForge is the only one that actually answers the phone. Will order again.
Questions, Answered
We accept STL, STEP, STP, and OBJ files. For best results we recommend STEP or STP for engineering parts. If you only have a sketch or a physical part, we offer reverse engineering services.
Standard lead time is 48 hours for most parts. Rush options are available for an additional fee, with some parts ready in as little as 12 hours. Production runs typically ship within five to seven business days.
Yes. Our in-house CAD team can help you optimize your design for 3D printing, fix mesh errors, or create a model from scratch. Design services are billed at $95 per hour.
If your part arrives damaged or does not match the approved specifications, we will reprint it at no cost. See our Refund Policy for full details.
