When you have a printer, cycle times can be much shorter…and a few fast cycles with a job shop will pay for a printer.

Small jobs from small customers are not a high priority for job shops. Neither are cheap jobs.

Having a printer means you are able to work on projects at 2am Sunday.

those are the tradeoffs. It sounds to me like 3d priting isn't even a good fit for what the guy wants to do.
