Perla extruder

After more than a year of pushing myself with various extruder topologies and feed screw designs, I've distilled the lessons learned into a new geometry that addresses the weak points and enables printing with elastomers. The innovative extruder features include: simple printing and assembly, effortless use and cleaning, and the capability to print with diverse materials including highly elastic ones. Additionally, it has a built-in potential for further development and a flexible model system that can be easily modified. This allows you to effortlessly adjust the nozzle diameter to significantly increase speed or attach the filament sensor to precisely control fusion. The extruder was successfully tested with E3D V6 normal hotend and Volcano, yielding outstanding results. Printing spare parts is relatively straightforward. We utilize PLA. Notably, main_body and idler must be printed with 100% infill. extruder_holder and sensor_holder are sufficient with 50% infill. Be sure to remove support material using a stationary knife and file the holes to loosen them if necessary. Don't forget to properly cut the PTFE tube at approximately 75 degrees angle and insert it from top to bottom. This is crucial for printing with elastomers. We recommend using mk8 and any preferred stepper motor (we utilize NEMA17). You can also print E3D V6 Groove mount or order one, whichever suits your preference.
