Most of the time my time spend operating my A1 Mini is... maybe 2-3 minutes per plate? Drag and drop into Bambu Studio, run the slicer, send the job to the printer, come back in 4 hours and grab my prints. I might need to break off the supports and clean them up - but with an injection molded kit I'd be snipping the sprues, cleaning up mold lines with a knife and gluing the models together anyway.

The commericial overhead rate for an SLA printer is about $5 a plate - the washing and curing steps can be largely automated, or even if they are done manually, it's not that much work.
