Hi @JulieSillam,
when you print PLA and have a heated bed you can print on glass.
When the print is finished and the object is cooled down you can just take it (or slide it) of the glass.
I clean the glass with alcohol before I start the print.
Only if you have very large/wide objects you have a risk of warping but you can prevent that by using Pritt glue only on the outter parts.
When you use pritt and can’t get the object off after cooling down (or using it on a cold bed) you can just take the whole bed and put it in some warm water. Wait for a while until the Pritt glue is solved by tge water and you can take off the part.
I hope that helps 
!
Kind regards, Guy
Thanks Guy for having taken the time to answer. This is super nice of you. I’ll definitely try that and let you know, but you look like a real pro, I have no doubt it will work
@sandrako shall we get back to printing ?
Best regards,
Julie
Hi Julie,
gladly done!
Kind regards, Guy
Julie,
What printer are you using?
What buildplate?
I use PLA on cold glass with diluted PVA glue (on a UM Classic) and the parts pop off loking like glass

If you are printing on the blue painter tape, what works best for me is to just soak it in isopropanol Alcohol so that it looses the bond with the platform, after a minute or two you can peel off the excess painter tape around the object and then with very little force remove the object from the remaining tape.
For this one, it was an Ultimaker 2. I have no clue about the build plate though…
Thanks James, will definitely use that trick also !
Best,
Julie
This solves everything!
We had this I think but can’t find it anymore…
A UM2 will have a glass build plat - so i am asuming the white is glue?
If you are using it hit then let it cool down first and the print should just pop off.
I fina ascraper (with a razor blade) works well to just start the popping off process

Nice one! I have a putty scraper for construction… sometimes it works. But this idea is even better… sharper! Mine won’t work on big areas attached to the bed.
Yes thats true. I actually got myself wider blue tape to make that less of an issue
- Consider blue painter’s tape. It is worth the price. Your parts will stay in place but won’t get stuck.
- Use some tools
- I mainly use a japanese spatula (translation from French) - La Boutique Du Carrossier 106
- I used to use a sharper tool, but I hurt myself and did some scratch on the plastic bed of my Replicator 2
- For some parts, you can use a screwdriver. It offers a great lever and is quite harmless.
- Proceed with caution. Many 3D printers’ accidents append during the removal and finishing proces.
