Direct metal laser sintering (DMLS) is an additive manufacturing technique that uses a carbon dioxide laser fired into a magnesium substrate to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
For the most part, laser engraving is considered the most popular engraving method for this type of material because the process is simple, cost-effective, fast, efficient and versatile. Acrylic laser engraves easily, vaporizing instantly with the touch of the laser beam and leaving behind bright white letters.
