Once the 3D print has finished, it must be removed from the build plate. There are several methods to use, depending on how the print has adhered to the build plate.
Wait for cool down
If you printed directly on to the glass plate without using an adhesive, and if the build plate was not leveled too tightly, the print may easily be removed once it is cool. Simply allow the build plate and the print to cool down after printing. The material will contract as it cools and you can easily remove the print from the build plate.
Use a spatula
If your print doesn’t remove from the build plate after cooling, you can use a spatula to remove the print. Place the spatula under the print and apply a small amount of force to remove the print.
Note: Take the glass plate out of the printer to avoid damaging the build plate clamps.
If neither of these methods work, remove the print using water. Remove the glass plate and print from the Ultimaker 3. Be careful not to burn your fingers if the glass plate is still warm. Run cool tap water on the back side of the plate to cool it quicker - the print material will contract more than with a normal cool down. Once the plate has cooled, the print can be popped off.
If glue was used on the glass plate, run lukewarm water over the print side of the plate to dissolve the glue. Once the glue has dissolved, it is easier to remove the print. If PVA was used, place the glass plate and print in water to dissolve the PVA - this makes print removal easier.
