NanoOne Green 3D Printer Offers Increased Precision, Ability to Work With Broad Range of Materials

UpNano (Vienna, Austria), a provider of high-performance 2-photon polymerization (2PP) 3D printing solutions, has added NanoOne green to its NanoOne series of 3D printers. The NanoOne green features a green wavelength of 515 nm and a laser power of 400 nm, offering increased precision and the ability to work with a broader range of standard and transparent materials. 

The company says the printer offers 30% higher precision compared to a 780-nm laser wavelength and the ability to work with a broader range of materials unlocks new research fields and industrial applications. This precision advancement enables new levels of detail, achieving detail elements below 100 nm in width. 

The printer also facilitates the use of transparent, biocompatible, non-fluorescent materials which are preferred in optics and microfluidics, where the conventional fluorescent photoinitiators are restrictive. The green laser also broadens material compatibility, enabling the use of existing photochemistries along with the development of innovative ones previously unattainable with standard 780-nm lasers.

“With the NanoOne green, we have extended our NanoOne product line with a tool that delivers ultrahigh resolution features and paves the way for diverse industrial applications,” says Bernhard Küenburg, UpNano CEO. 

All NanoOne printers feature UpNano’s patented adaptive resolution technology, which dynamically expands the width of the laser beam tenfold to speed up printing in bulk material areas or shrinks it where precision is needed. The company says this advancement makes the NanoOne range the highest performing and most adaptable 2PP 3D printers on the market, well suited for both research and industrial applications.

The NanoOne green, like the existing NanoOne models, is a compact desktop system that incorporates high-performance vibration isolation, a built-in clean room with a HEPA filter, and full compatibility with all existing NanoOne accessories. These include specialized fiber holders, wafer chucks and a heatable vat, all of which enhance system flexibility for diverse applications. By integrating this new wavelength, UpNano says its continues to meet the evolving needs of the 2PP 3D printing market, offering cutting-edge solutions that support breakthroughs in microfabrication, prototyping and scale-up.

NanoOne printing systems come in a ready-to-use standard configuration, but are also customizable with additional modules to suit specific customer requirements. The NanoOne printer series is capable of achieving resolutions below 100 nm across multiple scales — from nanometer to centimeter-sized objects by switching between different objectives as needed. The company’s technology supports a wide range of applications, from batch production to complex bioprinting in native cell environments, leveraging innovative materials, including fully biocompatible and fused silica options.
