Once your 3D print is finished it must be removed from the build plate. There are several methods to do this.
Caution: When using a brim, be aware of the danger of cutting yourself when removing the print from the build plate. Use a deburring tool to remove the brim once the print is taken from the build plate.
Wait for cool down
If you printed directly onto the build plate, simply allow the build plate and the print to cool down after printing. The material will contract as it cools, allowing you to easily remove the print from the build plate.
Use a spatula
If your print is still adhered to the build plate after cooling, you can use a spatula to remove the print. Place the spatula under the print, and keep it parallel to the build plate, and apply a small amount of force to remove the print. A spatula can also be used to carefully remove the remaining parts of the print from the build plate, such as the brim or support structures.
Caution: Take the build plate out of the printer to avoid damaging the build plate clamps.
If you printed on the build plate with glue and if neither of the above methods work, remove your print using water. Remove the build plate with print from the printer. Be careful not to burn your fingers if the build plate is still warm. Run cool tap water on the backside of the plate to cool it quickly. The print material will contract more than with normal cool down. Once cool, the print will pop off.
Alternatively, you can run lukewarm water over the print side of the plate to dissolve the glue. Once the glue is dissolved, it is easier to remove the print. If PVA was used, place the build plate and print in water to dissolve the PVA. This makes print removal easier.
