PS-CB-175-0500-DG PrimaSelect CARBON Filament, 1.75 mm, 500 g, Dark Grey

I can say without a doubt that is has become my go to filament, Love the finish, find it very easy to print (QQS -Pro 260 hardened steel nozzle genuine E3d 1v16 85 bed). Comes sealed but not in reusable bag, would recommend drying for few hours before printing for optimum results. Will definitely buy again.

I've been using this stuff for a little while now using a Prusa Mk3S with a hardened nozzle. Temps need to be a little higher than standard PETG. I'm running 245 nozzle and 85 bed in a lack enclosure. Ambient temp hovers around 38°C. Due to do carbon fibres the smallest layer height you can reliably go to is about 0.2, although I run stuff at 0.3mm with a 0.4nozzle. Its uchm much stronger than standard PETG. Surface quality is almost velvety, but rock hard. Seems more resilient to heat. If you need strong, tough prints for working parts then this is the one to go for.

I don’t often give 5 star reviews but in this instance I felt it warranted. I’ve used plenty of prima filaments of all ranges in PLA and PETG along with the select range with carbon. I have a specific requirement that calls for carbon fibre infused filament. I originally used colorfabb cf20 but found it printed so slow a few years ago then moved to a another brand but that used carbon dust and was not very good (just like the majority of unknown brand 1kg rolls from China despite claiming to use long strands etc) for a while I’ve been using carbonfill as I needed the consistency of colour between batches and quality of filament but even formfutura has been a letdown recently with colour variations and physical characteristics changes between rolls and needing drying. Primaselect is not quite as expensive as formfutura and like many other brand specials comes on lower weight rolls (although the filament is about 20% lighter than standard PETG) but of all the ones I’ve used the primaselect gives the best finish overall and prints with less tweaks than others but the best bit is consistency between rolls. Its a filament that delivers results each time and worth every penny. Don’t be fooled by cheaper alternatives

This stuff prints really nice but it's wrapped on the reel so poorly I worry about snags. It's priced over £30 so would expect it to be wrapped well for this and therefore probably wouldn't purchase again.

I love the finish on this filament. It feels quite textured and looks matte. I love the fact its PETG based not PLA. Its a bit expensive though given you only get 500g, but ive yet to find another filament out there to match its properties. Most other carbon fibre filaments come out light grey, this is more dark grey. This WILL wreck your nozzle if you dont have a hardened steel one though so be warned! Id recommend the nozzle X from e3d.
