Has anyone done a cost/hour analysis of operating the Glowforge in terms of figuring out a business model? I figure the factors include the following:
Straight labor for setup and takedown
Electricity (Is this negligible? No idea what total power draw is on the GF, 50 watt laser tube + other stuff. Maybe 100-150W? 200? Lets say 200, that’s 1 kWh per 5 hours of lasing. Feels pretty insignificant, even if my guess on power draw is way low. Are there specs released on this? Has anyone used a Kill-a-watt to see what it’s really pulling?)
Maintenance costs (mostly measured in labor and time, see below)
Laser lifespan (wear and tear)
Risk [Tricky to quantify here, but every job could lead to a fire or other catastrophe. Should that be considered?]
This doesn’t take into account the extraneous things like materials, labor for sales, and fufillment – but that’s by design. I am trying to limit my understanding to the costs of actually running a job.
This is also a fairly subjective thing based on what you think your labor is worth. Personally, I’m really expensive, but ymmv.
Is there an industry standard for these costs?
