New EXPERIMENTAL size 0.10mm and 0.15mm. For experts only! Microscopic prints. Needs well tuned UM and an experienced hand.
New EXPERIMENTAL size 1.0mm JET RSB100x. Anyone can print (Temp + 5%, Speed 15mm/s and work up from there. 7x flow compared to 0.40mm, so 15mm/s equals ca 105mm/s in plastic volume on 0.40 nozzle.
WHY JET RSB? These new nozzles are meant forÂ Speed! Plastic will flow more easily than in most other nozzles. Atomic pulls work very well! The inside geometry makes it much harder for plastic to hide in the corners, so changing color/filament type will be quicker and safer.
