Pa12-cf
Hi, I want to print an intake manifold for a car supercharger using PA12-CF nylon. What do I need to add or upgrade on my Prusa Core One printer to be able to print such parts?
RE: Pa12-cf
Hardened standard (not high flow) nozzle and appropriate print sheet for nylon. Typically at least 0.6 nozzle is recommended for CF stuff, and never high flow nozzles, both to reduce the chance of a clog. Expect a learning curve working with nylon.
RE: Pa12-cf
That's good advice. Additionally, if you print on a dedicated print surface ( Prusa PA nylon plate, for instance) don't use adhesive. It won't improve bed adhesion and eventually it might damage the PA coating of the plate.
Another thing, make sure that the Z-offset of the first layer is spot on. Don't trust blindly Prusa's marketing about that "always perfect first layer". Many users have learnt that this isn't always the case. Sometimes you need to adjust manually the Z-offset to avoid too much or too little squeezing of the filament. If the first layer is too low, it might be quite difficult to remove the print from the plate. This is specially important printing nylon filaments on a nylon coated plate.
Although 0.6 mm nozzles are recommended, I print on a regular basis Prusament PA11-CF with a 0.4 nozzle and I never had any clog, although not all CF filled filaments are the same. Other brands may contain larger carbon fibers and be more prone to clog.
