printing plate with or without PEI coating, manufactured from the finest milled cast aluminum material.
Coated with PEI, it enables direct printing with ABS, PLA, PETG and many other unaided filaments (e.g., kapton tape, ABS-acetone blend, painter's tape, etc.).
In the natural version you need aids to keep the printing on the surface. (e.g., optional glass plate, ABS-juice, Kapton tape, or the like).
