During this year’s trade fair formnext, the 3D microprinting technology company Nanoscribe showcases the rapid fabrication of structures with micrometer precision in millimeter dimensions for the first time. Nanoscribe’s Photonic Professional 3D microprinters are mainly used for nano- and microfabrication. New advances in 3D microprinting allow short print times of the smallest structures in millimeter sizes.
Nanoscribe’s recent developments are shifting the limits of basic two-photon polymerization (2PP) technology to new horizons. The technology is now bridging the gap between micro and macro 3D printing in terms of build size and precision, as shown in figure 1. This achievement opens up new application fields in rapid prototyping of high-precision parts, biomedical engineering, and micromechanics.
Nanoscribe’s 3D microprinters outperform conventional 3D printers in resolution with the ability to print structures in sizes that range from a few hundred nanometers to several millimeters. These capabilities have triggered the development of novel devices, such as 3D microscaffolds for cell culture, compound lens systems on a CMOS sensor, and functional components such as gears, springs, and filters.
The capabilities of Nanoscribe’s 3D microprinting enable submicron lateral feature sizes, and resolutions not yet available with other 3D printing techniques. Fused deposition modeling (FDM) and selective laser sintering (SLS) are limited in vertical and lateral resolution with layer thicknesses and smallest feature sizes in the range of several hundred micrometers. In the high-precision domain, stereolithography (SLA) as well as digital light processing (DLP) and polyjet are 3D technologies that provide sub-100 μm layer thicknesses.
