Micro Channels Formation
The SLE technique makes it possible to produce taper-free micron precision channels with a low surface roughness of ~200 nm RMS.
Threads for Screw
The SLE technology permits straightforward conversion of the desired CAD design to a 3D micropart. Even mm-size structures with a few micrometers of precision can be printed in this way.
Tesla valve microfluidic channels can be fabricated inside the volume of glass. This microchannel design allows the liquid to flow in only one direction.
The Geneva gear is an arbitrary-shaped micromechanical component and is one of the most used devices for producing intermittent rotary motion.
The channels in the glass along with polymeric micropillars form a microfluidic device where different types of inserted cells can form a complex cellular architecture and manipulate cell‑to-cell interactions.
The hybrid-fabrication approach enables rapid production of channels out of fused silica via laser ablation, while multiphoton polymerization is used to integrate fine-mesh 3D filters of arbitrary geometry inside the channel.
By selective laser etching (SLE), glass microstructures can be made and polymeric structures can be integrated into the glass microstructures using multiphoton polymerization (MPP).
Laser Surface Texturing
The femtosecond laser produces an oxidation formation on a titanium alloy surface. Varying colors can be achieved by creating oxide layers of different thicknesses.
Holes in Hard Metal
Femtosecond laser micro-drilling stands out by its accuracy and minimum heat affected zone. The process is applicable to a wide variety of materials, including different metals, ceramics, polymers, and glass.
Squares with rounded corners in a polymer. The pitch between the holes is substantially smaller than the size of the hole. Spaces are thin and straight, ablation edges are clear, and there is minimal thermal influence.
Laser processing precision makes it possible to engrave tiny QR codes on different material surfaces as well as imprinting QR codes into transparent material volume.
A hydrophobic surface formed on a copper alloy sample using femtosecond laser texturing. The contact angle between this surface and a water drop is 150 degrees, which means that the surface has the potential for self-cleaning, anti-icing and other properties linked to hydrophobicity.
