Questions

Common questions.

Which files do you accept?

STEP is best for engineering parts. STL and 3MF work for printing. Send native SolidWorks or Fusion 360 files if you want us to make changes.

How fast can I get parts?

Most FDM and SLA orders take 3 to 5 business days after you approve the quote. Rush orders can ship in 1 to 2 business days when machines are free.

Do you sign NDAs?

Yes. Ask before you send files and we will sign yours or send ours.

Can you fix my design if it will not print well?

Yes. Small fixes are noted in the quote. Larger redesigns are quoted as engineering time.

Do you ship outside New Jersey?

Yes, anywhere in the US. Local clients can pick up in Kearny.

What if I need 500 parts?

Above a few hundred parts we compare printing, MJF and injection molding and quote the cheapest route.
