For machine shops, fabricators and engineering teams

Put your shop's idle printers to work.

Your FDM printers sit idle between in-house jobs. Hotend Labs fills those hours with paid production work: prototypes, jigs, fixtures and short runs for customers who need parts, not a printer.

No application, no waiting list. Take jobs the same day.

Who it's for

Industrial shops with printers between jobs.

Machine shops, fabricators, and engineering and product teams that run FDM printers for in-house work and have hours left over. Fill the gaps between your own jobs with paid production work. Orders run from one part to 500, and you only take what fits around your schedule.

One machine is enough to start.
