Lithuanian institute of science is offering deep 3D laser engraving technology. Technology can be transferred through licensing, technical cooperation agreement.
The technology can be applied for various materials processing. During the preparation stage, the 3D object drawing is divided into individual layers. Afterwards, layer by layer material ablation is introduced. The use of picosecond laser pulses for processing ensures high processing quality and speed.
Advantages and innovations
Compared to nanosecond lasers, the short pulse - matter interaction time significantly reduces the thermal effects. The laser-induced heat diffusion is limited at such pulse durations. Therefore, melt formation and oxidation of the surface are significantly reduced. Also, burr formation is much lower compared to nanosecond laser processing. In the case of copper, an 8 mm¾/min ablation rate is achieved.
