Grenoble, France based Microlight3D, manufacturer of ultra hi-resolution 3D microprinting machines for industrial and scientific applications, has launched Altraspin, a compact 3D printer intended for producing highly complex micro-parts with sub-micron resolution.

Altraspin prints micro-parts for applications requiring high precision and a high-quality surface finish. These include the creation of micro-optics, micro-sensors and printing shapes that fit inside microfluidic devices. It is also suited to metamaterials, cell culture, tissue engineering, microrobotics, micromechanics and surface structuration.
“Microlight3D designed Altraspin to respond to manufacturing demands for more customization and the rapid prototyping of submicron parts that are not constrained by their geometric or organic shape,” said Denis Barbier, Microlight3D's president. “We have removed another constraint by extending user choice in the materials available for 3D microprinting. Altraspin is compatible with a wide range of polymers and biomaterials. The submicron resolution our technology achieves has been key to our growing success within the scientific community. We anticipate that industrial companies will also benefit from the advantages of our 3D-printer for micro-parts, reducing time-to-market.”

Altraspin is capable of achieving sub-micron resolution, as low as 0.2µm. Altraspin is based on a two-photon polymerization direct laser writing method plus its proprietary ‘continuous print flow’ technique, which is not constrained by the conventional additive layer-by-layer approach that limits standard 3D printing resolution to 25µm. It can print micro-parts so smooth that they do not require post-processing. 
Altraspin sub-micron 3D printer features a new TPP slicing tool, high-writing resolution and precision, and high-writing speeds, for complex 3D structures. It is compatible with any CAD models and files and its compact design is suited to laminar flow cabinets, clean-room and sterile environments, which prevent contamination of wafers.
Once a user has designed a 3D model using standard CAD tools and chosen an appropriate polymer material, Microlight3D's algorithms calculate the path that the laser will take to create the object. A laser pulse writes directly inside the liquid-material bath, solidifying the path it takes with the extreme precision of less than one micron. Once the operation is complete, a solvent washes away the excess monomer, allowing users to immediately handle the object, identical to the initial model.
Microlight3D will exhibit Altraspin at BIOS expo, San Francisco, California (USA), booth #8136, between February 2 - 3, 2019.

Specs of the Altraspin sub-micron 3D printer: 

  • Writing resolution: 0.2 to 3 microns
  • Max object size: 100 x 75 x 0.3 mm3
  • Surface roughness: Better than 20nm
  • Writing speed: Up to 5mm/s
  • Anti-vibration system: Included
