As the title states, I am getting “staining” on the bottom of my print.
BBL Matte PLA, Black.
Gold PEI Plate
Stock slicer settings and no glue.
First couple prints looked as you would expect, solid black and textured, now this. I did clean the plate and run another sample, same result. Anyone experience this before? Its not really a problem, but I would love to orient this part up so the texture is visible and with the “staining” I am not a fan.
Is it only happening with black matte PLA? What about black PLA basic?
I ran the test spool of basic PLA that came with my machine and did not see this on any of the prints. It was green not black though. I was wondering if something in the composition of the Matte finish is bleeding on to the bed?
I will pull a generic roll of PLA (Hatchbox) in black and run it. I did order some basic PLA, ASA and ABS from BBL to try as well.
Some use glue stick and a little heat or liquid glue to provide a barrier of sorts between the textured PEI and the print. That might stop the staining you are seeing.
Also, be sure to let the PEI plate cool before removing the part. They say it can damage the PEI to pull while warm/hot and that could be the kind of damage you see.
Does this to me if i pull the part before the plate is completely cool
Makes sense. I will give these a shot.
I haven’t used it much but so far Hatchbox is doing well by me too.
I’ve printed rolls and rolls of BL Matte Black on may different plates, including the gold plate. I have never had this happen.
Not saying it didn’t happen, just my experience. It’s definitely odd.
I find it’s dry out of the box and performs well.
@johnfcooley Thanks for the feedback, its good to know it performs well for others. I love the finish and want to use it more. I will load it up later this week again and run some more.
Hi All, I have the same identical issue with my P1S and Bambu Pla Matte Black… I have this strange effect in the bottom first layer. With other filament (normal pla green and organge, pla marble, petg traslucent) the first layer has no issue. I have tryed all, calibration, flow static, flow dinamic, first layer height… In all the condition I’m getting this bad effect on the surface. No other issue, no adesion issue. I have also tryed to dry the filament for 12h but no change…
Some one found a solution for this? The matte filament is very beautiful, but with this first layer it’s limitiative…
Letting the filament cool completely was the best solution i found, although not foolproof.
