Printing issues with Braskem FL900PP - CF

[Pedrones 0]

Hey! 

 

Last week I got the latest and newest Braskem Braskem FL900PP - CF printing material. It consists of an engineering-grade composite made from 100% recycled carbon fiber (CF) and meant to provide robust mechanical performance while maintaining a high degree of printability. But.. this last printability part is not working so good.

 

I have made all the recommended settings by Braskem for my Ultimaker S5 but still, have a big problem related to adhesion and warping of the material. I don't know which is the sweet spot for this material and wonder if somebody has been working with it before and can help me out! These are the settings I am currently using.

 

Any help, tips and tricks are very well received! Thanks!

That's a polypropylene filament.  aka pp.  That's probably the hardest thing to get to stick to glass.

 

UM recommends adhesion sheets so you could try that.  They sell them.  I've tried PP on adhesion sheets and it works just fine but I tore the sheets every time so it's a LOT of work putting them down, removing bubbles, then removing the sheets after removing the print (if they tear) (or print on a different area).

 

Alternatively you could try "magigoo pro pp".  My 3d printing buddies swear by magigoo.  I've never tried it but I hear good things.

 

I try to avoid PP wherever possible since there are so many alternative filaments with CF or GF (nylon is my favorite but there are petg/cpe alternatives, polycarbonate, abs (yuck - stinky)).  PP does have a few nice properties.  I think in particular it's more chemical resistant.

 Oh goshh I didn´t about this downside of PP... Anyway I´ll try both options, thanks a lot for that! I am curious about which other CF or GF filaments do you use. Actually I chose Braskem FL900PP CF because it was the only CF option available on the marketplace.

xstrand is on the marketplace - it's GF (not CF) but it's the best filled filament I've ever tested (only tested about 5 and haven't tested any in the last 3 years or so).

 

The profiles are overrated in my opinion.  If you are printing PA6 or Nylon filled filaments (CF or GF), then just use any generic nylon profile.  But definitely use the CC 0.6 core.

I just checked and you can get several types of xstrand including pp or pa6.  I recommend pa6 (which is nylon).  I have used the gf30-pa6.  Look most modern CF and GF filaments all work great.  xstrand has not cornered the market.  It's just one that I tried and it was excellent.
