Desktop Manufacturing

I'm going to be producing small quantities of specialized parts for a product.
I know what my filament costs are, but how much should I figure for machine time?
I don't need to price in my time, I'm just thinking that the machine will eventually wear out or need replacement parts/ maintenance.

Does anyone have even a fluffy number for cost per hour to run?

 

I've always heard $.50/g is a good estimate for a part cost

 

For machine time? Seems light, but I like that number.

 

Depending where you are and your electric costs, consumables, your time, not just machine time, I would say at least .75 is good.

 

I suppose I could plug this in to a kill a watt and find out what it draws, but I am more concerned about wear on the machine.

 

If we assume 10% power transfer efficiency then printer draws close to 15A at 12v that's ~200W of power.

Wear on the machine is hard to gauge. If everything works efficiently and doesn't fail, then the only real replaceable part is the nozzle. I'd say you get about 6 months of use and they cost like $8.
