Polymaker Fiberon PPS-CF10 Filament Black, 1.75mm, 0.5kg, Extreme Heat Resistance, Carbon Fiber Reinforced PPS, 3D Printing Filament, Ideal for Forming

Easy to print, crazy properties. It's expensive but you get what you pay for here. I can't express how neat this stuff is, it's like cast iron or ceramic. The best part is it prints like a dream, I've had 0 issue printing the carbon or glass filled PPS filaments.

PPS-CF10. The filament came dry out of the box and it is easy to print at 320C/90C, 10mm3. Very good bed adhesion at 80-90C on textured PEI with no glue, 100C almost too much adhesion. Since I have a heated chamber, I used it, but manufacturer says that heated chamber is not necessary. However, filament should be handled very carefully as it is very stiff, has rough surface, and it is extremely brittle, so ensure you have as straight path to extruder as possible. At this point I have only completed some test prints, and small parts, and I have not encountered any warping. One important mention is Polymaker's great support (I have used email). They are very responsive, they attempt to understand what you need, and will find the information if you have a specific question. In my case, I wanted to confirm that the filament has properties of an insulator despite having CF content. Per TDS, Surface Resistivity ANSI ESD S11.1, >10^12 Ω. The value is confirmed by the support and by my own measurements.

Stuff is great. 5 stars. Just don’t print it like you would regular PPS-CF otherwise it will delaminate and warp. It likes being printed cool, and I mean 310-315c maximum chambered. 320 if you’re open-air any higher and it will droop out of the nozzle and mess up the Z calibration steps. Glue stick not required, it stays on regular PEI. It’s fun to print, looks great, no moisture issues even after sitting out for 24 hours. It just works.

If you have a suitable, enclosed 3D printer, with a very high temperature Hotend.... Fiberon PPS-CF10 is the greatest! It prints well with no unmanageable warping and prints come out with good precision of dimensions provided it is dry. Parts are strong, stiff, stable, extremely temperature resistant and non-flammable.... this just refuses to burn, even when held in a propane torch, it just melts. It does need to be dry but is fairly easy to dry in an oven set to 100C. Expensive? Not really for a high-grade Engineering material. My new go-to.

the title says it all, WOW! I was expecting to have to experiment with this filament in order to get a good print out of it, it's what I've always had to do with any filament with carbon fiber in it but nope! I used the recommended minimum settings of 310c on the hot end and a bed temp of 90c, a setting that is pre-programmed in the Creality K2 printer by the way, I wasn't expecting a PPS-CF pre-programmed setting but there it was, and it works PERFECTLY with this. Fiberon also says that a heated chamber isnt needed but I use a 50c heated chamber anyway just in case. So far I have printed almost half the 500gram spool making about 2 dozen prints and ZERO failures! With the right settings this stuff prints as easily as PLA. the ONLY issue that I have had so far is this stuff does NOT like to bend through PTFE tubes, if there is a slightly too sharp bend it WILL break in the tube. It's something I've come to expect in the first 2 layers, oddly enough it's ONLY within the first 2 layers, after refeeding it in it prints just fine for the rest of the print. Yes, this stuff is a bit pricey, for a half kilo spool but I'm already planning on getting more........potentially a LOT more. Fiberon, never change this stuff! It's fantastic!
