A glass plate is especially recommended for raftless 3D printing as it provides your models with a better quality of bottom surfaces. The glass plate can easily be installed on the heatbed using special clips and screws once the perforated plate is removed. You can use the glass plate with the M300 Dual, M200 Plus as well as M300 Plus. If you want to switch from the perforated plate to the glass plate, follow the instructions below.

The following manual shows the M300 Dual replacement procedure. For the M200 Plus and M300 Plus, this procedure looks the same.
