The Original Carbon Fiber Composite PLA

Carbon Fiber PLA Filament

$5.00 USD


The original is still the best! World's First Carbon Fiber PLA filament was kickstarted by ProtoPlant nearly 5 years ago. Others try, but can't match the quality and ease of printing experience afforded by this product. Available at a cost low enough for everyday printing, try a mammoth 3kg spool for large format printing! 1.75mm diameter 3kg spools contain more than 1 km of filament!  How cool is that?!?!

We Started a Trend with the Original Easy Printing Exotic!

Protopasta Carbon Fiber PLA is based on our easy printing, high quality PLA. Made from the highest quality, dry ingredients and extruded with care in our Washington facility on our own purpose-built extrusion systems. CFPLA prints are demonstrably more rigid with easy processing (often using standard PLA settings) and support removal.  Excellent layer adhesion and minimal warpage even without a heated bed make this a great everyday exotic for accurate parts. Layer lines disappear with the beautiful matte black finish.  Also has a slight sheen due to the embedded carbon making it very photogenic!

**This filament is slightly more abrasive than standard PLA. Be prepared to replace your nozzle and do 1st layer adjustment after prolonged use or upgrade to a wear resistant nozzle for less maintenance.

  • Available in 1.75 & 2.85 (3) mm diameters.
  • 500g is on a 8" diameter spool & 3kg is on a 12" diameter spool.
  • Usable on most PLA-compatible printers, such as Lulzbot, Makerbot, FlashForge, Dremel, Ultimaker, Printrbot, and more!

In filament form, CFPLA is slightly more brittle than standard PLA, and requires extra care when handling. 

Processing is comparable to standard PLA. No heated bed required. Process may be less consistent on smaller nozzles and/or bowden type machines, 

We frequently print using direct-drive systems with 0.4mm nozzles and print as high as 240C, though suggest 0.6mm and 210-230C for the best experience.

Protopasta CF PLA; Crappy or Carbon-y?

So far my experience with Protopasta’s Carbon Fiber PLA has been nothing short of excellent. The filament was easy to work with, if a tad brittle, and I got an incredible matte texture on every print. Wouldn’t change a thing about it! 10/10 Carbon-y.

I low-key fell in love with this stuff.

It's perfect honestly. It's pretty, durable, and prints pretty easy. That's always what I'm looking for in a material. I don't even care that it absolutely murders my hardened steel nozzles.

So Protopasta Carbon Fiber is good enough to get away with murder? I'll take it! ;-)

Affordable, easy to print.

I really like the matte finish. It's not as shiny as some competitors. This is also an easy filament to print. It doesn't leave buildup on our nozzles like other brands. Best of all it's priced affordably enough for my company to use for high volume printing. We don't need the special features of HTPLA, so I'm glad this is offered. Due to the carbon content of this filament, we have found it has increased friction in PTFE tubing compared to non-composite PLA. We had to decrease the distance from our dry boxes to our printers to accommodate this. Overall it we're very pleased and will continue ordering in the future.

Best I’ve Printed

The PLA printed perfect. This material has a high carbon content, unlike other manufacturers. I really like the surface finish. It helps to hide layer lines and ghosting really well. I would recommend using a direct drive printer, the carbon didn’t glide smoothly in the Bowden tube. This isn’t a problem for me but just some advice. This will be my go to for professional prints. The surface finish when printed using a MK3S+ is extremely professional.
