We all talk about bed adhesion problems such as prints not sticking to the bed, warping, or the prints coming off in mid-print. But there is another problem, which is quite the opposite: 3D prints stick too well to the print bed and can’t be removed easily. In this situation, you need to work more gently, as any amount of too much force can damage the heatbed or build plate. So, here is the detailed step-by-step guide to removing stuck filament from a 3D printer bed.
How to Remove Stuck Filament from a 3D Printer Bed?
There are many ways to remove stuck filament or a 3D print from a 3D printer bed. First, try to remove it using a scraper. If the build plate is removable, take it out from the heat bed. You can also heat the bed to the printing temperature and apply a little bit of pressure. Alternatively, you can put the build plate in the freezer for 15 to 20 minutes, as this sudden change in temperature will decrease the filament grip.
Why Filament get Stuck to 3D Printer Bed
There could be many reasons why your filament or 3D print gets stuck to the 3D printer bed, but primarily it happens due to inadequate bed leveling and poor bed adhesion. When the bed isn’t leveled properly, the nozzle might be too close to the heat bed. This makes the filament squish excessively, leading to a stuck print.
Sometimes, your filament type also plays a big role in this problem. For example, PETG (Polyethylene terephthalate glycol) is a popular 3D printing filament due to its high strength, weather resistance, and easy-to-print properties. However, PETG has the tendency to form a strong bond with print surfaces, especially with materials like glass, making it really hard to remove.
Methods to Remove the stuck filament from 3D Printer Bed
Before using these methods, try to remove the 3D print by applying gentle pressure. If it comes off, that’s good; otherwise, don’t apply too much pressure, or you could damage the build and gantry. If your print is delicate, putting pressure might break it.
Preheat the bed
In this method, preheat the 3D printer’s bed to the printing temperature of the stuck filament object. Heating the bed temporarily softens the initial layer of the object, which weakens the adhesion and eases the grip of the object on the heat bed.
Then, take a thin scraper or spatula and try to place it at the point where the object sticks to the bed. Gently attempt to lift the print, and after removal, clean the bed with isopropyl alcohol to remove all leftover residue.
If the above method is not working for you or if it is damaging the bottom layer of the print try this method.
If your printer’s build plate is removable, then remove the build and put it in the freezer for 15 to 20 minutes. Cooling the filament contracts the molecular structure, making the 3D print brittle. So, when little pressure is applied to the object, it will easily come off the build plate.
Using Hair Dryer or Heatgun
Sometimes the preheat method does not work. In that case, you use a hair dryer or heat gun to apply heat to the stuck filament. Focusing heat on the object, especially at the bottom and after a few seconds the object will lose grip, and by applying slight pressure or using a scraper, you can easily remove the stuck filament.

If you have used some kind of adhesive like hairspray or glue stick to stick your print but is now stuck and is not coming off, do this:
We would recommend you to use some kind of solvent like Isopropyl alcohol or acetone, just apply or spray small amount of solvent around the print, wait for few minutes, and see the magic it will help in the breakage of bond between print and the bed then apply some pressure using hand or you scraper and most probably it will come off very easily.

How to Avoid 3D Print Adhesion Issues
Now you know how you can remove the stuck 3D print from the bed, but it is tedious and requires a lot of effort. So, if you don’t want this to happen to you again, here are some preventive measures you can adopt that will help you to easily remove the filament or 3D print.
We discussed some of the best solutions to remove the stuck filament from the bed. But doing this after every print is tedious and requires extra effort. So, if you don’t want this to happen to you again, here are some preventive measures you can adopt that will help you to easily remove the filament or 3D print.
Proper Bed Leveling
Leveling your 3D printer’s bed is important for getting proper bed adhesion; the distance between the nozzle and bed should not be too high. Otherwise, the print will not stick to the bed and might come off in mid-printing.
If the nozzle is too close to the bed, it will cause the filament to stick too well to the bed, making it really hard to remove. So, make sure to do proper bed leveling.
Using tape such as painter’s tape or blue masking tape on your 3D printer bed can improve the bed adhesion, and it will also make it easier to remove prints, as tape provides a slightly textured surface on which molten filament can stick well.
Just apply a fresh layer of tape on the bed before starting the print, and after the print is done, you can easily remove it by taking off the tape.
Using Magnetic or Flexible Plate
By using a magnetic or flexible build plate, you can easily remove the prints. These plates are made up of materials like spring steel or PEI, which allows prints to stick well while they’re hot and can be easily removed when they get cold.
If your print is not coming off, you can remove the build plate from the heatbed and give it a simple bend or twist, and the print will pop off easily.
The proper bed leveling is the easiest solution for stuck filament. Keep checking your bed after a few prints to see if it’s level or not. I would recommend installing an ABL (auto bed leveling) sensor in your 3D printer so that you don’t have to keep doing it.
Also, keep the filament type in mind, like PETG, which has the tendency for strong adhesion. Try to replace your build plate with a flexible or magnetic build. I can guarantee it’s worth the investment.
How do you get PLA stuck out of a bed?
- To remove stuck PLA from bed is quite easier in comparison to other materials, you can preheat the bed then apply some light pressure to make sure safe removal or you use the scraper to gently pull it off.
How do you remove stuck plastic from a 3D printer bed?
- Preheat the bed, then gently lift the stuck plastic using a scraper. Make sure you use minimal pressure to prevent damage to the bed or you can use other methods like using heatgun or solvents like acetone or Isopropyl alcohol
Are solvents a good method to remove stuck filament?
- Yes, solvents like isopropyl alcohol work effectively, just apply a small amount of solvent and wait for a few minutes then gently remove the filament using a scraper.
