I’m very new to the 3D printing world. I just purchased a new P1S, it prints with PLA perfect. I just switched to ASA black filament and have yet to be successful on any prints. It gets the first 5.50 mm of layers done then the print loses contact with the textured plate and then follows the hot head around. Sometimes it doesn’t even make it to 5.50 mm it can mess up when it’s 1 mm thick.
At first I thought it was losing grip on the textured plate (maybe a temperature setting?). I tried both with and without glue. I clean the plate after each failed attempt with water and soap. It is completely dry before going back in the printer.
After the 15th try on a different setting I noticed a piece sticking up like it did not bond with the rest of the print. When the hot head made it back to that part of the print it caught it and drug the print with the hot head. The filament is brand new from BAMBU 2 days ago. It went straight to from the sealed package to the enclosed AMS staging area on top of the printer. I would think that it is still good unless I got a bad batch from the factory?
I have read other troubleshooting tips on this forum but I am struggling on finding any that apply to my issues. Any suggestions would be greatly appreciated. Thanks in advanced.
This looks like it could be a filament moisture problem. Unfortunately, a factory sealed package is no guarantee of adequate dryness.
Bambu suggests drying their ASA for a minimum of 8 hours at 80C in a forced air type oven. Details on drying filament can be found in the Wiki and the Filament Guide.
ASA and ABS and Nylon and PETG can be harder to print. These plastics have large coefficients of thermal expansion, which in this case means they shrink a lot as they cool. That shrinkage generates forces that can peel the print off the build plate.
Try cranking up the build plate temp and slowing down the first layer, and if your P1S isn’t enclosed, minimize any cool breezes that might blow across the print while it’s printing.
That being said, your filament looks a little blobby to me. Just because it came out of a sealed bag doesn’t mean it’s dry, so you should dry it to be sure. Overnight, not just a few hours. Then, after drying, you could try it again with the automatic flow calibrations, but I’d do the manual calibrations to maximize your chances of success.
Also, it’s not completely clear from the pictures, but it looks like you might not have very much of the print actually in contact with the build plate. Most of the underside looks like overhangs that don’t touch the plate. So having a small contact area can also be a problem. There’s a slicer option to add a “skirt” around the first layer, to increase the surface area of the first layer, to increase its ability to hold on to the build plate. The extra material can be easily peeled away from the finished print.
