That is awesome! So many questions! Do you have issues with first layer adhesion or the Nylon delaminating? Do you use the default Nylon profile for the machine? Do you have the Prusa MK3 in an enclosure to keep the ambient temperature up? We have been looking to do something similar on our two Prusa MK3s, but have heard Nylon can be tricky. Thanks!

Nice! Has anyone by chance tested this material vs. Markforged Onyx in the context of FRC applications? Seems like it should be similar.

Re: pic: Cabon Fiber Reinforced Nylon Filament 3d Printed Parts - FRC 3986

So I just got a Prusa and I also ordered the carbon-fiber filament that they sell.

So far I've only bought the stock brass nozzle, so I need different one to print the carbon fiber.

But the book says I just need the hardened steel nozzle.

So tell me, the ruby nozzle--is that better? Do I need it?

Will I need to take it back off to print PLA etc?

The difference between the Ruby and a hardened steel nozzle is how much filament it can put through before needing to be replaced. A hardened steel nozzle will open up as the abrasive CF filament wears at it. This happens in a few kilos of material. The Ruby is more durable, and can basically handle as much abrasive filament as you can throw at it.

Last I checked, it would take ~4 steel nozzles to equal the cost of a Ruby. That might have changed, but that equated to ~16 kilos of material printed on the estimate of 4 kilos of CF filament wearing out a steel nozzle. You'll probably want to update those numbers with whatever the current prices are, and want to do your own research on how long it will take to wear out a steel nozzle. There are various estimates out there based on what kind of steel the nozzle is.

If you're planning on aggressively printing lots of parts, a Ruby nozzle is probably worth it. If it's not the primary use case for the printer, it may not be.

This reminds me a lot of the oynx from the markFordged printers that my team uses, utmost the strongest prints I've ever seen and worked with. If teams have the money I really recommend this kind of print even if it's not used that often.
