Re: Polycarbonate is brittle or I am doing something wrong? - 4 years ago
Quotenophead Polycarbonate sheets can be bent cold without cracking, so it should not be brittle, quite the opposite. I know that PET is brittle if it is printed with absorbed moisture, it needs to be dry, perhaps PC is the same. Interesting! I have a feeling that PC is more flexible with absorbed moisture, like nylon. But I did not check it for sure. EDIT: I dry PC before printing, and printby Khumarahn - Printing

I don't have much UV inside the printer.... Can anyone suggest a tried and true PC filament, preferably designed for high temperature applications?by Khumarahn - Printing
Re: Polycarbonate is brittle or I am doing something wrong? - 4 years ago
QuoteVDX ... seems to be "pure" PC, without additives for adjusting physical and longterm behaviour ... Do you suggest that what I see is normal for a virgin polycarbonate, and that polycarbonate with additives would be better? I have been looking at polycarbonates with additives, they normally print at low temperatures (240-260C), which suggests that they are not very heat resistant...by Khumarahn - Printing
Polycarbonate is brittle or I am doing something wrong? - 4 years ago
Hi, I am looking for an advice about polycarbonate, which seems strangely brittle. I *think* I know how to print PC, at least I can get strong and dimensionally accurate results, at least initially. But the parts which I used for my printer (e.g. hotend mount, bed mounts) crack with time, see my photo. If in use long enough, they just fall apart along the crack lines. I replace what I can withby Khumarahn - Printing
Re: Precision Piezo Z-probe Now available. - 4 years ago
Say, chimera is attached by four m3 screws in a square with edge length 10mm. Is there a piezo sensor which would fit in between these screws?by Khumarahn - General
Water cooled chimera - 4 years ago
Hi! I am looking for a mount for water cooled chimera. It is attached from the rear on four m3 bolts: I did not find an existing mount. I could design one in cad, but I am not sure what it should look like. What would be my options?by Khumarahn - General
