This technology brings the following advantages
The newly released M3DS-SHD has two coaters that can contain different materials. One is for soft material (Resin A), the other is for hard material (Resin B).
The Two Coaters
The two coaters of M3DS-SHD apply two different resins alternately on the coating sheet, and each time one of the resins is applied, the light from the projector cures it. By repeating this process, the printer delivers the object composed with the two resins.
To Clean up the Boundary of Different Materials - Cleaner
However, it was difficult to obtain clean and sharp boundary between the two resins only with this process, because the resins adhered on the object and mixed easily.
