Polymaker Fiberon PPS-CF10 Filament Black 1.75mm 0.5KG

So apparently this stuff was originally invented for use in high temperature, nasty environments like chemical production. An interesting side effect is that it rings like metal when struck, so you can actually make basic musical instruments out of it. I confirmed this by printing a tin whistle, and it actually sounds like a metal tin whistle. Be aware that it is insanely hard to print. You will need a printer that can go up to 300 Celsius, which is not super common. You will also definitely want an enclosure. Despite the ringing property, it isn't actually very brittle, instead it is surprisingly soft and loves to stick to things.

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!

Good stuff!

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.

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.

Love it

Print a bell. It rings like metal. Very sonorous.

This stuff is not cheap, however it does seem to print well for the few parts I have printed. I have only printed small parts so far. I'm using a Qidi plus 4, stock settings for this filament. I printed a bunch of extruder parts for my Voron V0.1, as some ABS printed parts melted due to an overheating motor. The parts are extremely strong and stiff, to the point that for some parts that are expected to flex a bit, this stuff just breaks. This is not a bad thing, just use this for parts you want or need to be rigid. I ordered a second roll, and cant wait to start printing with it again and really get it dialed in.

Excelente

As advertised. Is it brittle, does it have bad adhesion without high chamber temp, yes. But that’s just how the material is, and not a fault of the product. Does it survive automotive fluids at acids at boiling temperatures, yes. Does it sound like metal, yes. Would I buy it again, yes. While moisture might not do anything to its strength, you can definitely notice a print quality difference from when it’s fresh out of a blast oven vs. wet. Unfortunately still needs to live in a dry box.

It just isn't dimensionally stable. Bed adhesion is horrid without glue, but even with (120c bed, 65c chamber, 340c nozzle) it warps like no tomorrow. it sounds like metal, is very stiff and heat resistant, but in any situation where it's material properties would be useful they're invalidated due to its inability to be the slightest bit dimensionally accurate.
