Having trouble sticking to bed
When I print one item (using ABS-T), it prints well with good adhesion just by cleaning well with isopropanol. But if I then copy that item into six identical items, one or more do not adhere and they all then just ball up in a mess. I tried the KORES “adhesive” and it made it muchworse. (how do I remove that stuff?).
How can I increase the adhesion to the bed?
Thanks for your responses.
I may have resolved it. The Z was set to -625, so i set it to -600 and it seems to be working. This learning curve is steep. But fun.
Wish i could delete the previous entry. My printing for 2 hours in and then one of the segments broke off the plate! Disaster. The cross-section of my first thread is VERY flat. I see in the Prusa video their plant with many machines running powder-coated plates with multiple images... and they do not have the adhesions problem. I can not get ANYTHING to stick to my powder coated plate. Nothing! What am i missing here?
The only way I could get PLA to stick to the textured bed was with glue stick. On the other hand the textured bed works 100% perfect when I print with PETG...perhaps that's why PRUSA uses PETG on a textured bed for the MK3S parts, they can't get PLA to stick either...LOL
ABS is a pain to print with, but here are few things you need to do that will help.
- Leveling your bed and calibrating your Z height
- This is especially important when printing more than one item. Your bed might be level in the middle, but outside areas might fluctuate. You really should print a bed leveling set and try to pick the best "Z height setting" that will help the entire build surface
- Consider An ABS Slurry to aid in adhesion
- Some people I talk to who routinely print with ABS apply Acetone to a small amount of ABS that turns it into a liquidy ABS slurry, then apply this to the build surface
- Hair Spray!
- Simple, easy, and works for pretty much every printing material including Nylon. This is what I use and has been great for me.
