#bad bed adhesion on weird bed

So I just brought home a free hand me down printer from a college workshop I work in that like anyone who would have known about this printer has graduated or transferred and I haven't found as straightforward of an answer as I feel like I need to like look at purchasing anything for it since it runs fine.

It has this weird blue bed and ive never printed on anything like it so i have no idea what to do about adhesion, i have leveled it and tried raising the bed higher than the printer thinks i need and if the print isnt mostly flat i end up with adhesion issues even if i put some glue on the bed.

Looking online i saw someone say scrape the blue off if its damaged and print on the glass and one of the guys i worked with for a short time before he transferred had said the bed was two sided so you could print on the glass back but it doesnt fit well upside down so im not sure i want to try it. Im used to the magnetic beds the printers ive used more have where its really flexible and the glass makes me worried about getting prints off.

I also saw someone say they bought a pei sheet bed for it and like i have no idea how to know if any online would work with what i have.

So to sum everything up i want to know
Is the blue bed not great for adhesion or is there something i can do to fix it?
Is the glass side better than the blue and what do i even do to make sure i can get prints off glass?
Can i get a pei sheet bed that would work with what i have already and do i need to know anything besides how big the bed is?

I tried to get pictures of this keychain(?) printing where one of them was holding onto the other because it wasnt attached to the bed anymore and an attempt to show the weird texture of the blue plate that really only shows someone elses print engraved into it which may be part of the problem lol

Congratulations on acquiring a 3D printer! It sounds like you have some questions about the bed adhesion and potential upgrades. Here are some answers to your queries:

  1. The blue bed you mentioned is likely a BuildTak or similar material. It is designed to provide good adhesion for most prints. However, sometimes it can lose its effectiveness if it becomes damaged or worn out. You can try cleaning the bed surface with isopropyl alcohol or soapy water to remove any oils or residues that may be hindering adhesion.

  2. The glass side of the bed is an alternative surface you can use. Some users prefer glass due to its flatness and smoothness, which can help with bed adhesion. To print on glass, you can apply a thin layer of adhesive, such as hairspray or glue stick, on the surface before starting your print. Once the print is finished, allow the bed to cool down, and the print should easily pop off the glass.

  3. Yes, you can upgrade to a PEI sheet bed. PEI (Polyetherimide) is a popul...

I did actually wash it with the dishes after isopropyl alcohol didnt work so im assuming its just worn out

#

I feel like i would rather have a flexible bed but i have no idea how i would go about attaching it on here

#

Its a flashforge finder if that helps anyone look at how the bed is attached
Part of me wants to just get one that would fit on top of the bed and just clip it on somehow but the thing that holds the bed is so chunky i wonder if theres a better option?

why

also stay away from older flashforge printers...
