GMP Additiv’ specializes in metal selective laser melting for complex products with high added value.

GMP Additiv’ is a major partner in the field, its total control over the entire value chain means it can offer the best solution for every client.


Direct metal laser melting is an additive manufacturing technology that relies on heat, generated by a laser, to melt powder metal. This high power (400W) YAG laser is able to create a 3D object in a layer-by-layer fashion.

This technology creates near fully dense (99.9%) complex geometrical forms that cannot otherwise be obtained by traditional methods, such as lattice, porous, or bio mimicking structures.

This production method, with its associated short lead times, is ideal for prototypes and small series, and opens the door to new market opportunities.
