Laser Cut Transparent Clear Hotend 1.75mm Rev1.0

Tried various materials for the hotend, including J-Head peek, nylon, PU carbon, and then all aluminum. Finally, I tried something new and the results are promising. The heating time is fast and extrusion efficiency is around 20-30% better. Initially, with direct drive gear filament, the extrusion speed was set at 160mm/sec in Marlin settings. Now, it's down to 120mm/sec and I'm still fine-tuning for optimal print results. While pulling out the filament while it's still hot, I noticed that the filament end tip melts less than with other hotends. The heat from the aluminum heater block doesn't really transfer up to the hotend body, but the best part is that it's transparent and clear! I've tested printing with outer perimeter speeds of 30, 40, 50, and 70mm/sec, and the results show that I can push it even further. The faster I print, the smoother the filament extrusion flow becomes. The E motor is now more powerful and requires less tension for filament grip at the idler. I was printing with DIY ABS filament, which had a diameter of 1.65 to 2.00mm. If I use better-tolerance filament, the results will be even better. With hair spray and a heatbed set at 80°C, the ABS sticks very well too! I'll upload and share more videos later. Keep an eye out for updates and visit our site at http://www.3dprinter.my!
