The printer seems very impressive and I have baked the kickstarter. My intention will be to produce quite large CF-Nylon functional parts which are prone to warping. I’m looking at using 3DXTech PA6-CF filament which recommends a chamber heated to 80C, clearly this is a passively heated chamber which I see reaches about 60C. Have you done any testing where the temperatures reach this level? Do you see any problems reaching 60C and maintaining it over a long print? I imagine 60C would be fine but I’m afraid with sensitive large prints that extra 20C might be useful…
Also you can get a 300W PTC fan heater and temp controller with Thermistor from Aliexpress for around $10-15 to give the chamber some help. Do you think this would be wise? Are the electronics well isolated from the chamber (I understand a lot of good quality steppers work well even as the temp exceeds 100C but I worry about other components/plastics in the chamber. Do you hav any info if the printer has been at elevated temps? After all, 100C is PEKK and maybe even PEEK territory! It’d be great to have an easy to use consumer printer capable of producing engineering parts, it could really open up a lot of opportunities for creative basement engineers…
In fact given how little extra an actively heated enclosure would be and given the mature firmware support it’s a shame such a promising printer as this doesn’t allow you to set chamber temp like you do nozzle and bed temp. I suppose there might be some safety aspects that keep this feature out of consumer products (which means we also miss out on a convenient filament oven/dryer).
Sharing Any info on the chamber or your experiences using more exotic materials would be of great interest to myself at least.
Keep up the good work,
James
