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.
At the beginning of the print the surface was up to 46°C in the middle and about 30°C at the edges.
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 up to (80°C according to the specs)
