PLA - Post processing: if it aint one problem it's another :)

Recommended Posts

Just been giving my red PLA 'Thomas the Tank Engine' cookie cutter a light coat of Crystal Kote matte varnish straight out of the printer (after cooling) to help future proof the print. Lo and behold now some of the print has developed a patchy white bloom on the red.

Something in this PLA doesn't play well with this varnish. Sigh.

Hi kman, and thank you for sacrificing some of your Christmas shopping and printing time :)

  • Spray. Thinly several times with in-between drying.
  • Cooled prints.
  • No humidity warnings or issues that i could see
  • I've been running a dehumidifier in the print room. Humidity hovers between 39% and 43%.
  • Haven't tried thinners yet
  • Filament has been kept dry in supplied ziplock packaging with some dessicant.
  • Yes, Wanhao filament. :angry:

My noggin is officially full! :)
