The LAPIS Process

It starts with the laying of a fresh sheet over a build plate.

A laser welds through the sheet, bonding it firmly to the build plate.

The laser then ablates the unwanted areas, according to CAD design input.

The process repeats until the part is fully constructed.

Additive Manufacturing

Subtractive Manufacturing

Using the laser exclusively in cutting mode,

layer-by-layer deconstruction, engraving and contactless machining can all be achieved.

Performance that Matters

Fully dense parts

Welding fuses 0% porosity sheets into a single solid, giving excellent mechanical, electrical and thermal properties.

High resolution features

Excellent surface finish

As-printed roughness: Ra ~4µm (3× as good as powder-based).

No sandblasting, machining, grinding, debinding or sintering.

Minimum feature size ~ 50 µm

Reproducible accuracy ~ 20 µm

Reliability

≤ 5% deviation of mechanical properties across production batches.

Reduced Material Cost

Sheet prices at a fraction of powder cost.
