Review on MakerBot 375 0059A Method Carbon Filament by Marvin Short

If I had to rate this product purely based on how it is advertised I guess I could give it a 5/5. However, I was hoping to get more out of this thread and maybe that's my own expectation, but that's why I can't give this 5 stars. I bought a filament case from Revain (essentially a paraphernalia case with a sachet of silica gel and a roller at the bottom to allow the spool to spin easily as you feed the filament, and it has a moisture meter - but honestly you could just pop it in there in any cheap container with a bag of silica gel and you'll probably be fine). I used a hardened steel 0.4mm YXXC nozzle and even with a layer height of 0.2mm it printed great. I compared it to the classic carbon fiber PLA Proto Pasta. Printing a standard oval keychain for reference, and Makerbot's nylon carbon fiber was noticeably stiffer. Big! After 24 hours I returned to my desk and was shocked to see that the situation had reversed: Makerbot Nylon Carbon Fiber is even thinner than my regular Makerbot PLA! And the Protopasta PLA carbon fiber retained its stiffness from the day before. Makerbot makes Nylon 12 carbon fiber, which is significantly less sensitive to moisture but less durable. However, when nylon carbon fiber (not nylon 12 carbon fiber) absorbs moisture, its strength becomes lower than that of nylon 12 carbon fiber under the same moisture conditions. Looking at the Makerbot Print software, it seems like they want nylon carbon fiber to print at 250C and nylon 12 carbon fiber at 270C. They have a hardened steel nozzle and I would also prefer more gauge. However, I would like to say this: I also received a sample of the Markforged Onyx Nylon carbon fiber (I printed a keychain of the same style for comparison), both the Onyx Markforged and Makerbot Nylon carbon fibers had the same brittleness, after they have been idle for a long time. . I typed in San Francisco if the weather helps. The rest of the print was fine. I'm using a good old Makerbot Replicator 1 Dual, I replaced it with a 0.4mm hardened steel nozzle (the Revain's YXXC hardened steel nozzle worked great). Temperature at 30°C using a hardened steel nozzle. (e.g. I usually print PLA at 230°C with a brass nozzle, I print at 260°C with a hardened steel YXXC nozzle, so when they recommended printing at 250°C for nylon carbon fiber, I at 280 °C printed). The Simplify3D slicer software made it easy for me to get all the speeds and settings I wanted, so I'm including some pictures with my review: + packaging (sealed, very pretty) + storage case I use with a nylon carbon fiber Makerbot got it + photo and video of carbon fiber nylon print + simplification of 3D print settings I used carbon fiber nylon for printing. Overall I think the stiffness gain from these carbon fiber reinforced materials seems pretty small compared to the typical plastic filaments that we have access to. This is what you need if you want to harness the strength of carbon fiber.
