I am working on an experiment to determine how variable your print’s quality will be based on where it is on the printing bed. We have a few of these printers at my university and over time they have started to show some issues with certain areas of the bed. I am conducting a research project to identify whether or not the location on the bed where the print takes place is of concern.
We have 3 TAZ 5’s and at this point I need to develop three levels for my analysis. For these levels I will need to figure out how variable the temperature across the bed can be based on the input temp and break the 300 x 300 mm plate into 3 distinct areas where the temperature would be noticeably different. I know the plate is Borosilicate glass and I have found the thermal conductivity for the material, however I am assuming the heater is designed to be extremely uniform with the grid like pattern.
As I have researched information on the plate but I cannot find how the plate is heated. I have found the heating element available on the lulzbot site but is the heating through the grid channels totally uniform? I am assuming it is hard to heat up a rectangle uniformly, that’s why pizzas are round.
