As we got these great exotic filaments from our sponsor E3D we need a nozzle to print them. Because these filaments contain small carbon fiber particles which are abrasive to the 3D printing nozzle. To protect our nozzle from wearing out we contacted the people of the The Olsson Ruby nozzle, they were happy to provide us one of there high end nozzles so we could now print exotic filaments for our robot. Thank you Olsson Ruby for teaming up with us!
