Temperature is a recurring theme on these pages. When I got my second machine towards the end of last year, I decided to do a side by side comparison. My first machine had already been modified to incorporate temperature control in the print area (more later). I printed the same file on the two printers side by side at the same time. Room ambient temperature was 15C and in my modified machine the print area was at 27C. The print from the temperature controlled machine was definitely crisper and so I modified number 2.
On the top of each printer is a digital temperature controller with a sensor that can be seen to the right of the z slide in the picture. This controls a constant temperature PTC electric fan heater (12V 150W) that is stuck to the floor of the print chamber to the left of the z slide. The fan is always on to circulate the air and blows onto the back of the printer. A separate 12V 20A PSU drives the heating system for both machines. The extraction fan is disconnected so as not to suck out the warm air and the fumes that some find bothersome. I have the upper temperature set for 27C with 1C range. Delay typically takes the temperature down to 25.9C before rising to an overshoot of about 27.8C. This is air temperature and so the thermal mass of the VAT and resin smooths this out to probably just under 27C. The result is total consistency of prints and no discernable difference between the machines. All parts came from Amazon. From KKmoon 200-240V Digital temperature Controller thermocouple -40C to 120C with Sensor. With hind sight, I should have got the 12V model. From Kggy-eu Constant Temperature PTC Electric Fan Heater for Car Small Space Heating Incubator (12V 150W). Remove a mounting lug from this to allow it to be stuck to the base plate.. From LEDSONE LED Power Supply Unit 240Watts 12V 20A Constant Voltage DC. This is good for driving two heating systems.
