Is nylon ok for brass hotends? Ive been wanting to try some taulman stuff but have heard that the stronger stuff (specifically carbon fiber infused) is very abrasive and will quickly wear down the tip… Also, name what you think is the strongest, easiest to print material is
The carbon fiber infused stuff absolutely destroys things. @Sanjay_Mortimer was talking to me at #MRRF about how they were experimenting with some of the first alloys, they weren’t paying attention, and the filament running over the top of their frame on the Mendel90 actually started to saw the frame in half over time.
Wow. Wouldn’t want to use that anymore lol
Honestly, ABS is about the best compromise material you can use. Its curling can be handled, it doesn’t need crazy temps, it’s amazing inside basically any nozzle you can think of (the cheap chinese nozzles can even successfully extrude the stuff), some formulations can smell nasty, but it’s not going to melt in your car in the summer heat, etc. It also needs a heated bed, so there’s some higher upfront costs involved. (If you’re looking at Nylon, you probably already have a heated bed though)
PLA is good if you don’t need heat tolerance, but it’s sticky when molten - which makes it difficult to extrude from an engineering standpoint. But it’s amazing as far as lack of curl, ease of use, etc as long as you don’t have a knockoff hotend.
Nylon is awesome, but requires a higher temp to extrude properly. It’s a somewhat soft material, but Taulman has so many formulations, I believe he’s got some stiffer stuff available now. Like PLA - you don’t want to use Nylon if you’re near heat – it’ll deform permanently at temperatures as low as 50C or so. However, things you print with Nylon (when printed correctly) are virtually indestructible. The formulations I’ve printed have the same tendency to curl as ABS; but with the added need to handle moisture content in the filament (or else you get bubbling, popping, weird oozing, etc)
@Abc_Def None of our lines are loaded with carbon fiber. We now have Alloy 910 a new High tensile, high durability material that’s easy to print at 245C to 255C. I will note that we are looking into carbon fiber nylon, but it’s a few months out.
I was talking about a different company when referring to carbon fiber. I will definitely try out your nylon when i get the money @Tom_Martz
