Prusament PC Blend Carbon Fiber Black, pccf

Has anyone had good luck printing Prusament PC Blend Carbon Fiber Black? 

I have blobs or marks on the top of my parts.

With the extrusion multiplier set at Prusaslicers default 1.04, printing in vase mode the walls measure .546mm, when printing the same model with Pla and Petg the walls measured .457mm.

Not sure which direction to go to get nice pccf prints.

It is also difficult to get the textured finish from the plate.

If anyone has had good luck please share your settings.

Using:

Mk3s+ at 285/110c

Prusaslicer 2.5.0

Textured and satin sheets.

Thanks, Eric

Good results with the base settings.  I had to dry it.

How long did you dry it for and what temp?

I dried mine for seven days in a photo dry box.  It does not use heat.

I haven't used PCCF myself, only PC.  I have a PrintDry Pro dryer and I dried PC at 75 degrees for more than six hours.

The default setting is probably fine using the exact same hardened steel nozzle as they used when configuring it. Maybe you need a nozzle that limit flows and doesn't transfer heat greatly to use the default settings.

In my case I'm using a .4mm tungsten carbide nozzle. I had to reduce the temp to 275c and extrusion multiplier to 0.97 to get better result. Even with those changes I mostly run my print with "external perimeter first" because there is still a little bit of overextrusion. If not when I use 4 perimeters my parts are definitely larger and I can't use precise fit between parts. The only downside of using external perimeter first is sometime the look of the finished parts are not perfect and also the overhangs are mostly bad.

I'm using the Satin sheet only.

I choose PCCF over PACF because I didn't want to struggle with a dehydrator. And indeed there is no stringing.
But I found the PCCF tend to foam a tiny bit. That could explain the over-thickness and poor fit. I should test with filament dried. A PrintDry Dryer 2.0 is on my whishing list but I have no place for it.

The foaming might be by hydration.  PCCF will hydrate over time too.  The stinginess of PCCF tends to bran dependent.  I get very little stringing with Prusament PC Blend with CF.

RE:

When I talked about PCCF, it was indeed Prusament PC Blend with CF. I should have mentioned it.
Otherwise it is a fantastic material to print.

RE:

It is a great filament.  I need a better source in the US.

Sorry for late replay! I was browsing looking for something else and came across your thread… I love printing with PC-CF but like you I struggled initially with the extrusion multiplier and getting accurate prints. In the end I found the trick was to use a multiplier of 1.02 and the adjusting the perimeters and external perimeter to 0.4mm instead of 0.45mm. It now prints so cleanly it’s hard to see the layer lines 👍

RE:

I just made some extrusion multiplier calibration for the PCCF today because now I have a dryer.

I got:

  • 0.83 when the filament is not dried.
  • 1.04 when the filament is dried.

PCCF foam quite a lot when not dried.

My driyer is the Eibos3D.
