Hi guys, does anyone know what I’m doing wrong? I got white spots on my printed parts and I’m not sure why. I’m printing with PLA. First I tried to wipe it of, but that doesn’t work. So I thought it’s something related to my print bed surface and changed it. But it didn’t change anything. I already printed things with this spool, but it’s the first time I got this effects. I also tried using a different PLA (light blue). Due to the color, it’s really hard to see, but it happens also with other PLA spools. Any ideas? Thanks for any advices.
It’s quite hard to remove, but other people are complaining about the same behaviour for Flashforge Dreamer (hard to remove). So I’m not sure whether it’s related to the stickiness of the surface, but you’ll never know. I calibrated the printed right before the print. But maybe I need to calibrate with some more distance. Will try it again. Thanks
Ah, ok. Now I got it. Sorry, I read that I should take hair spray instead of dryer and have than been completely into the stickiness topic in my mind. Sorry for that. Now I know what you are trying to tell me and yes, it sounds like a good idea ?. Will give it a try later. Thanks.
You are right. It seems if the object is slightly bent when removing it from the bed, that the material is stressed and gets white at some spots. Can easily be reproduced if you take any other plastic and bend it a few times. When using the hair dryer the material softens and begins melting again. This makes the white spots disappear. Now when thinking it over it all sounds logical. Thanks again.
This is quite good guide Print Quality Guide | Simplify3D Software 82 From what you have mentioned you could have blobs and zits on your prints, Take a look at that section in the link above and try the suggested fixes
I think the bottom layer of the object stuck too fast to the print bed that a part of the bottom layer got stuck and it didn’t come out as a whole. For better outcomes, you can use a heated print bed to get the desired outcomes.
