Rapid Prototyping of 3D Models with Smallest Dimensions

May 4,2018

3D printing enables the quick fabrication of almost arbitrarily complex parts starting from a 3D CAD model. Widely spread 3D printing techniques such as SLA or FDM are limited to features and details that are larger than approximately 10 µm at best. With the technique of two-photon polymerization, however, it is possible to 3D print nano- and microstructures, but it can also be used for millimeter-sized parts with micrometer features and great shape accuracy. Nanoscribe’s 3D printer Photonic Professional GT makes use of this technique and its fabrication capabilities embedded in a classic 3D printing workflow. As known from conventional 3D printers, the printing process begins with the import of an STL model and ends with a rinse of the finished polymer part in a development bath. This results in complicated and functional parts of the smallest dimensions.
