Object keeps coming loose from bed...

Hi Everyone...

My printer seems to be doing quite well these days. My only challenge has to do with objects coming loose from the bed. I suspect it has to do with the constant movement of the bed - which ultimately jars the object loose. It usually happens with heavier objects, and somewhere between 50% and 70% completion.

I've tried printing directly on the bed, with blue tape, and even with blue tape reversed. I have a PLA model, so I cannot adjust the heat of the bed.

Any tips would be appreciated. We've lost a handful of great projects.

Thanks,

Iggy.

 

... I've even thought of stopping the print job 1/2 way through, and then tacking the base of the object with a few beads from a glue gun. However, I'm hoping to find other solutions before I try that. I really don't want to get in the habit of guessing when to stop, glue, and restart a project.

 

Just to share my experience:
- Hairspray directly on the glass didn't work well for me, besides that it's quite a mess to clean up from time to time.
- Normal white/beige painters tape (the fine one, not the rough) without glue worked best for me for PLA. If you have a large area printed on the bed and a fragile object, it gets quite a challenge to remove it.
- going to ABS (which you probably won't do), I had to go to blue painters tape + glue.

 

You can also try adding some Brim to the print to get more stick. Slic3r -> Print Settings -> Skirt and Brim -> Brim width.

You didn't say exactly what your parts are but my guess is if you use a good sized brim you'll have a much better shot at getting a part to stay stuck down for the duration of the print.

 

Tries Brim yesterday. It does what it should but it's still though to remove, and it doesn't look as smooth as if printed without. Maybe dependent on the object, though.

"Should", yes, in theory. I'll post pics....
