Pretty interesting, they are printing with temp of 390 degrees Celsius. Take a look of their site http://www.minifactory.fi/en/3d-printer/

Impressive we use glass fill peak In Our products and is some tough stuff. Would bet you need good heated bed and elevated temperature around print.
A heated build chamber is better than not, but I’m surprised 55°C ambient and 125° bed was enough to make a nice part. Their own specs say that machine maxes out at 50 and 120, respectively.
@Jeff_DeMaagd I read that they have passive heating in the chamber, so that why it’s not so hot. I guess it’s just heated bed which is heating the whole chamber. They have also hepa filtration which is sucking air out of the printer for sure.
I was really impressed about those nozzle temps!
E3D and B3 Pico can handle those temps, as can many other all-metal designs, provided you cool it enough to prevent heat creep. The main thing is getting a high temperature sensor and being able to modify Marlin to use it. I put a thermocouple on an E3 for a customer and he used it to build PEEK at 410°. I had an incomplete thermistor table for the B3, so I don’t know what temp it reached. All I remember is the stainless barrel turned a golden finish and the brass nozzle turned a shade of metalic purple I’ve not seen before.
@Jeff_DeMaagd Okay, well that is logical. I’ve made hotend my self for my printer and it is similiar to E3D design except it’s water cooled. I should put a thermistor inside a cooling element so I could check how hot the PTFE tubing gets at the end of it.
400 degrees is pretty high temperature for aluminium!
