Hi there, So I’m not a total n00b to 3D printing, but I’m not a pro either, so I thought I’d post here to get some insight on my suspicions.
I downloaded this little gizmo thing off Thingiverse. I didn’t design it. For several years, I had a InfuriEnder 5 which I got about 3 good prints out of in a dozen. So I upgraded to a Bambu Labs A1 with AMS Lite, which I love. Everything I’ve printed (and it’s been A LOT) has printed flawlessly with no input from me, until this little gizmo thing.
As you can see, it is printing a bit stringy, and I know enough to know it’s very likely because it’s basically trying to print in thin air without supports and the layers arent adhering to each other in the horizontal areas. Now, it doesn’t really have major issues. It ends up perfectly usable but I want it to be better. Preferably without supports. The designer says it doesn’t need supports but all of the places that this happens is clearly where things are horizontal “out in space”. For example, the stringy bits of the main photo above, that piece printed flipped from the way it’s sitting in the photo, so it would have printed the dome up.
ANYWAY. Could this be improved by just slowing down the printer to encourage better layer adhesion or something? I am trying to avoid supports because once it works out, I want to print a TON of these and I want to avoid a lot of post cleanup.
I’d suggest lowering your layer height and possibly trying to flip and print the dome convex side down, possibly with some supports if it’s not flat. You might have to do some post prep but it should be a lot easier for the layers to stick in that orientation
Edit: I apologize you said no supports. I still think lowering layer height might help here
