Hi, I have recently purchased a 3d printer, printing ABS is however an issue due to uneven temperature gradients and uneven cooling of layers (it warps and cracks a lot), i would like to heat the enclosure of said printer to around 80 Degrees Celsius (between the Solid and the Creep temperatures of 70 and 90) and keep it constant, the motors, bearings, electronics etc etc will be insulated from the heat.
I'm trying to decide on what heater wattage/type i should use to achieve this the area of the heated enclosure will be around 0.2x0.3x0.4m, the walls are aluminium and the outside air is still. So far i have worked out that it would take 1.47KJ to raise the temperature from 30 to 80 degrees in an ideal system through Q=mCp(t1-T2), however how would i account for heat loss through the walls/roof etc and how would this offer guidance on what power of heater i will require?
Any information would be greatly appreciated.
