Topic: Stuck to bed

Ok so i’m different to everyone else in that I had a print that firmly stuck to the heated bed on my SD4, no ABS/Acetone gloop, no glass and hairspray, just plain old kapton tape.  Whilst trying to remove it with the spatula/scraper for around 5 minutes I managed to snap it in two, nothing that can't be fixed with some glue, just a shame it stuck so well that it came to that.  Finally got it removed after 20 minutes of prying, some of which entailed the SD4 moving across the desk with the pressure I had to use to loosen the remains off the print from the bed.

It was the Ultimaker Ligthsaber, and I was printing at .1mm with solid infill, no supports, speed had been slowed down a little and it took 21hrs 23mins and 31 secs to print.  I was thinking it was probably the time it took that caused it to stick so well to the bed, would I be correct in this assumption?

Re: Stuck to bed

Slowing down the first few layers certainly helps with adhesion, I only use straight kapton tape also just make sure it is clean and heat is even. temperature differential helps with removal of prints so if it is sticking try to cool the surface more... upside down airduster, ice cubes, etc...

Re: Stuck to bed

The ABS is by Form Futura, I get it via the imakr store in the UK

This is the first time it has done this usually, releases with a bit of pressure, prying with spatula/scraper.

Forgot to mention before, but the bed was at room temp, as the print had finished whilst I was out collecting our kids from school, approx 1hr between it finishing and me getting back to remove the print.

Holding up well with the liquid poly and model filler I used to patch it back together will post a better image when I have painted it, just give me a week or so wink
