Initial
- Dr. Joshua Pearce's paper - Feb 2017 - [1]
- Energy consumption of 3D printing - based on paper above - 1 KwHr/100 grams of print
- Another source of energy cost Indicates 5 hours of printing at 50 watt power consumption rate for a 100 gram print. 25 hours total. About 12 cents for this print - factor of 4 lower than Pearce paper regarding energy costs.
- 10kwhr/kg - or 50 cents per pound energy of printing cost assuming grid electricity. Energy costs are significant. According to Pearce paper. This appears to be way too high. Check calculations.
- Precious Plastic extruder - energy cost -
- Cost of ABS resin -
Discussion
In above scenario, cost would be reduced by 2/3 if we went straight from resin to 3D print, without having to make filament. This, if an effective resin feeding system + pellet based extruder were available, this would be a preferred route for large 3D printed objects.
Filament Maker Efficiency
- 5kW for 1 kg in 1 Hr = 25 cents per lb of filament made at 10 cent/kwhr energy cost. [2]
