Thermal imaging of Snapmaker A350

Out of curiosity I did some thermal imaging of my Snapmaker A350 while printing the test vase with Snapmaker filament and measured the heatbed temperature. [flir_20200213T190456] At the beginning of the print the surface was up to 46°C in the middle and about 30°C at the edges. [flir_20200213T190505] [flir_20200213T205413] While printing the first layer the surface was up to >47°C and stayed that way during the rest of the print. Next time I’ll see what temperatures the heated bed can get…

Thermal Images of 3D Print Bed

I needed a really weak excuse to buy an almost $400 thermal camera attachment for my phone, so I rationalized that taking some shots of my A350 print bed could help give clues to bad bed adhesion on the outer areas of the print bed. I found that the temp variation between the middle and outside parts of the bed is too small to matter, and therefore has nothing to do with my bed adhesion woes But now I have a thermal camera Here’s me heating the bed to 80°c withOUT th…

A350 Heatbed heat distribution

Because of some adhesion problems I was curious about the heat distribution of my A350. Following images are done by a Flir E4+ at 80° C heatbed temperature: Snapmaker A350 original printing mat: [image] [image] Printing on glas: [image] [image] The heatplate itself has some hot and cold spots: [image]
