A modified type of vat photopolymerization for metal additive manufacturing that does not use a liquid vat. Instead, a feedstock consisting of metal particles and a photopolymer that is solid at room temperature is melted across the previous build layer to create a new liquid build layer. A DLP projector projects ultraviolet light onto the build layer to selectively cure the material. The layer is then cooled, and the uncured feedstock solidifies, providing support. Each layer is constructed this way to create a green part. After the full part is built, heat is applied to liquefy the uncured build material. The green part then undergoes debinding and sintering to create a fully dense metal part. This process is offered by Incus 3D.
Abbreviated as LMM.
