Oh, we’ve been sitting on this one for a while.
[Josef Prusa], brainchild behind what is probably the most popular 3D printer, has just unleashed a new hot end that is capable of printing objects in polycarbonate, PEEK, and nylon.
This new hot end is completely made out of stainless steel – there are no plastic parts made out PTFE or PEEK to keep the heat from transferring up to the extruder. Because the Prusa Nozzle can print these plastics, it’s also now possible to print parts for other hot ends such as the J Head and the Budaschnozzle.
We ran into [Prusa] at NYC Maker Faire a few months ago, and he was kind enough to go over the advancements in his new nozzle and new i3 printer. So far, it looks like the lack of a PEEK insulator isn’t doing the new hot end any harm – [Prusa] has left molten plastic in the nozzle for a few hours and nothing bad has come of it.
You can check out the interview below.
Again, thanks to [Prusa] for granting us an interview and providing some free advertising for Hackaday’s hosts for the NYC Maker Faire. Before you complain about the delay in getting this interview out to you, don’t worry; I slapped a few Makerbot stickers on the back of [Prusa]‘s jacket. Everything’s cool.
