Nanoscribe’s 3D Microfabrication systems enable rapid small series production

Karlsruhe / Frankfurt.  At Formnext, the leading additive manufacturing conference and trade fair, Nanoscribe presents high-precision 3D printing capabilities for small series production of components in the millimeter scale.

Nanoscribe offers advanced printing solutions with the Photonic Professional GT2 3D printer to fabricate millimeter-sized parts of 10 to 100 mm³ in shortest times. Until recently, the materialization of designs with millimeter dimensions was a challenge for the technology of Two-Photon Polymerization, originally developed for nano- and microfabrication. A further development of Nanoscribe’s 3D printer with an optimal combination of hardware, software and photoresins now offers high-precision 3D printing beyond the micrometer scale. This opens the way to small series production of mesoscale precision parts.

Rapid prototyping of precision components

Based on Two-Photon Polymerization technology, Nanoscribe 3D printers transform digital models directly into physical objects with maximum precision. To start working with the printers straightaway, the company has developed ‘3D Microfabrication Solutions Sets’. They feature precision objective lenses, high-resolution photoresins and application-specific optimized software recipes, each combined for different applications. The Large Features Set, for example, is designed for the fabrication of mesoscale parts. This allows to accurately cure more photosensitive material per pass, significantly reducing the print time needed for larger structures. The printing speed improves from 0.8 up to 6.8 mm³ per hour. The faster printing shortens the design-to-prototype time and enables the fabrication of millimeter-sized parts in small series.

At Formnext (hall 11.1, booth A74), Nanoscribe presents examples of mechanical components fabricated by the Photonic Professional GT2 using the Large Features Set. Mechanical components of filigree and complex designs with a diameter of about 1 millimeter will be showcased. Each of these components has been printed in 5 minutes.
