Hey everyone, I was wondering if you could help me out with an issue that I’ve had for a long time now that I never bothered to fix till now. On medium to large prints that require a large flat space on the build plate, I noticed not exactly stringing, but some abnormal texture that appears that can sometimes ruin larger prints. I mainly deal with smaller stuff so it didn’t really bother me but now it does. Anyone know what to do? Also if you look closely some parts of the layer are fine but then a few mm over, the pattern resumes.
I was using Bambu PLA tough along with deafult print settings for such filament.
The phenomena has a technical term “Dirty plate syndrome”.
But seriously, don’t overthink this. Take the plate and wash it with dishwashing detergent. In the US, Dawn is best and in the EU it goes under the brand Fairy Liquid. Smear a generous amount on the plate, run your kitchen sink at the hottest and most forceful amount and spray off the soap until it’s clear and repeat. Then pat dry with a paper towel and try it again.
Another alternative is to increase the bed temp by 5-10 degrees. But if the plate has any contaminants, it will only produce limited results.
A very effective test to determine how clean you plate actually is, is a first layer test. This can be done by taking a cube primitive, scaling it to 250x250x0.20mm and center it. That comes to one layer of filament on a 0.40 nozzle. If there is any contaminant on your build plate, it will become extremely obvious like in your photo.
