I haven't kept track of the time spent computer modeling, but if I had to guess I'd say there's at least 40 to 50 hours spent doing that. There's been a lot of finessing of the design, not so much for aesthetics, but more for how the parts fit together. Design, print, fit, check, revise, print, fit, check... repeat...
As far as printing, everything has been in batches, sometimes filling the printer, sometimes just a couple of parts. But an estimate would be about 60 hours to print all the parts. The phaser is made up of about 45 separate parts, not including hardware like magnets, pins and screws.
The plan though is to print a new set of master parts, clean them up so the surfaces are perfect (even with this printer there are some surface imperfections) and then make molds of all the parts. Then I should be able to cast a complete set of parts for one phaser in a couple of hours.
