Anyone ever see filament that leaves a fine white powder all over everything on the printer? I’m repairing one for Tampa Hackerspace today and everywhere around the nozzle and over the entire machine where it’s typically printing (underside of the carriage) is covered in this white film/powder. The filament that was in the nozzle was white and very brittle…anyone ever see this before?
Any idea if this stuff could be dangerous to work with?
I have used LOTS of White/polar white ABS and have never experienced this.
Yep, I can second seeing it after printing lots of PETG. It’ll deposit on anything relatively near the nozzle.
@Alex_Skoruppa , that’s exactly what this looks like! Thanks!
Yeah have it too
So, Don’t Lick your extruder /hot end assembly. “Check!”
Only with PETG, it’s kinda annoying 
Interesting, I would have guessed it’s hairspray / 3DLac deposits. I’ll need to keep an eye on my printers, they use up a lot of polyester filaments
I can confirm takai-san my giant Delta has this same white powder. I burn through kilos of petg filament from esun. Haven’t tried another manufacturer yet. I am quite happy with the esun stuff for now.
Also i used glue stick and hairspray at times and the power deposit appears in either case
Hair spray will not look like white powder unless you scrape it off the bed with a razor blade.
@NathanielStenzel it does if the aerosol gets enough time to dry. I once had to clean up a Witbox @Nils_Hitze used to spray 3Dlac in, looked like a bag of cocaine exploded next to it.
Wasn’t me, don’t look at me, it was flour!
Lololol
@Thomas_Sanladerer what brand of hairspray? I use Aquanet Extra Hold.
@NathanielStenzel like, actual 3DLac
But can you get all day hold for your up-do with that?
@Stephen_Baird yes. In fact, @Sanjay_Mortimer can vouch for that.
3dLac != hairspray
Yeah, all of my printers have this around the layer cooling fans, not so much the blocks anymore as I use the E3D Socks, as 99% of what I print is PETG and Co-Polymers. To use Tom’s analogy they do look like they have been on a cocaine bender. Some filaments are worse than others, eg ColorFabb NGEN will cake things up pretty quickly.
