Vienna-based two-photon polymerization (2PP) 3D printing specialist UpNano has used a high-power laser to speed up the printing of parts with nano and microscale resolution across 12 orders of magnitude.
The laser, in addition to an optimized optical pathway, patented adaptive resolution technology, and smart algorithms for laser scanning, enabled the firm’s NanoOne printing system to produce highly precise parts with nano and micrometer resolution which range from centimeter to micrometer in size.
“We developed and patented an innovative adaptive resolution technology for our 3D printing system,” said Peter Gruber, head of technology and co-founder of UpNano. “Together with an optimized optical path and smart algorithms, we can utilize the full laser power up to one watt, which is several times more than in comparable systems.”

Two-photon 3D printing
2PP 3D printing is an ultra-precise production technology that, up until recently, could only be optimized for a limited range of scale. Production in the centimeter-range was also considered time-consuming and therefore unattractive for quantitative production within industrial applications.
Nanoscribe, a fellow manufacturer of two-photon additive manufacturing systems, introduced a new …
