rigid.ink – The Best, Pure 1.75mm Carbonyte Filament (Carbon Nylon), 500g Spool

I don't often leave feedback but I have been so impressed with this filament (albeit after a relatively short period of use) that I wanted to share my thoughts.I have experience of printing with, pla, abs, petg, nylon, flexible filaments and filaments with additives such as wood or carbon fibre. However, this was the first time I have tried a nylon filament with carbon fibre reinforcement and was pleased when it arrived because I had been looking for CF PA filament that could be easily obtained in the UK for some time.As ever the amazon ordering and rigid ink fulfilment was swift and easy. So far, the filament has printed very well at my normal nylon settings (260C print head, 112C bed temp). What has been a pleasant surprise was the lack of warping in prints that so often affects nylon as it cools and contracts. The carbon fibre seems to minimise the shrinkage and my parts have been able to be printed successfully without rafts or brims onto a glass bed with minimal glue or spray coatings. This means I am far more likely to turn to using this nylon as it is quick to use and gives repeatable prints.The filament itself comes out with a matt black and slightly coarse finish as you would expect but it prints cleanly and accurately. I am expecting it to cause wear to my nozzle (despite it being stainless steel) as my CF PETG filament did this over time. I would suggest having spare nozzles if you can.The printed parts are incredibly strong and stiff. I am yet to do quantitative tests between this filament and my other nylon filaments. The difference in elastic deformation is very obvious when comparing two identical parts (one in Bridge Nylon and the other in Carbonyte) but it remains to be seen whether this has a detrimental impact on the UTS.The only negative about this filament is the price. I understand why it is more costly than standard filaments but it does seem disproportionately expensive when compared with NylonX and CarbonX. This is unlikely to prevent me from buying it though, as its print quality and material properties are so impressive.

Very solid and strong product. Getting started with it was very easy, 265 C printing temperature and 110 C bed temperature on BuildTak bed material, no layer cooling and 30 mm/s print speed. Stainless steel nozzle is a must like with any other carbon material. I had to scale down the extrusion multiplier to 0.7, to get the perfect layer width. Layer adhesion is perfect not like some other carbon material I tried. A bit pricey, but worth the money if you need a strong material you can reliable print with.
