This build plate is an original replacement part for the Mars 4 3D printer from Elegoo. The plate is made of aluminum alloy, which makes it sturdy and durable and not easy to deform. This ensures stable and reliable performance during 3D printing. The oxidised, sandblasted surface ensures good first layer adhesion and makes it easy to remove the model after printing. The plate is easy to install and clean, making it an ideal choice for your projects.
