Review on 🖨️ Enhanced Dimensional Accuracy with PRILINE Polycarbonate Filament: A Top-Grade 3D Printing Solution by Ryan Bennett

. I have a Qidi Tech X-MAX printer, hardened extruder nozzle B (0.4mm). This black filament for the PRILINE PC 1.75 3D printer required some adjustments. I downloaded Thingiverse's xyz calibration cube and it took 14 prints of settings back and forth with Qidi tech support to get it really perfect. They offer a Qidi Print profile for polycarbonate, but that was VERY far off. This stuff is NOT real PC, it's heavily mixed with something else. I hope it can handle enough temperatures as my plan was to make parts that fit inside the car (not the engine bay, around the seat/dash). The PC doesn't need to bend or warp in the extreme temperatures that cars experience in the summer. Here are my print settings for my X-Max, YMMV, but hopefully this helps someone else. — Flow rate 100% — Release of retraction 5 mm at 70 mm/s and retraction at layer change — Release of freewheel 0.1 mm3, min. volume 0.17 mm3, speed 90%, outer wall width 0.2 mm - layer height 0.2 mm, Initial height 0.3mm, line width 0.4mm - number of wall lines 2, top layers 8, bottom 3 layers - optimization of print order on walls - infill density 55% cube pattern - 10% overlap skip, 20% overlap overlap - print in advance - Rockbuilder glue type , 2 lines, distance 4 mm, speed 20 mm/s - print speed 50 mm/s, wall speed 25 mm/s, upper/lower speed 40 mm/s, support speed 40 mm/s - traveling speed 200 mm/s, minimum shift time 15 s - temp 235°C, initial layer 240°C - build plate temp 90°C , initial layer 100C - turn on print cooling, turn on camera loop (specific to closed printers like mine) - add support everywhere, 45 bar angles, zig zag pattern, Un Support Density 40% - Turn on Travel Prime, Speed 100% UPDATE 1 I spoke to priline support and they did their best for me. Upgrade from 4 to 5 stars.
