In the process of resin 3d printing, having a perfect first layer is crucial. But just completing machine leveling is not enough. Checking the flatness and wear of the bed for your 3D printer is also one of the key factors that determine whether printing can be successful. Your resin build plate needs to be replaced with a new one if it shows either of two signs: deep scratches on the surface and being deformed or bent. Let's find out the specifics of these two signs and how to determine if you need to replace your build platform.
What are the types of resin 3D printer build plate?
Anycubic Photon series printer has two types of build plates. The first one is traditional brushed metal plates, and the other one is the best 3D printer bed. It has laser-engraved surface, featuring a textured checkerboard pattern which significantly improves 3D printer bed adhesion and printing success rate. For example, the new arrival Anycubic Photon Mono M5s comes equipped with a laser-engraved resin build plate that has upgraded quality and adhesion.
What are the signs that you need to replace your resin 3D printer build plate?
1. Deep scratches on the resin build plate
Deep scratches on your 3D printing bed will ruin your parts like resin prints warping. Since a metal scraper is usually used to remove the sticky resin objects from the build plate, minor scratches on the plate are normal and do not affect its use. However, with repeated use, the minor scratches can become deeper, resulting in rough bumps and burrs on the surface of the build plate. This can damage the FEP film and ultimately lead to resin leakage from the vat to the LCD resin.
2. Deformed and bent resin build plates
An uneven and dished build platform must be replaced to prevent defects in your 3d prints. When checking your plate, use tools like calipers or steel rulers with a straight edge to ensure that they are not deformed and affect the test results. Place the tool on the build plate and test its flatness. If you are difficult to confirm it, try shining a light source between them and observe if any light passes through the gap. Make sure to test all areas of your resin build plate, instead of just testing one spot. If there is any unevenness, you might need to replace the build platform.
