Tilt Compensation Maximizes Precision in 2PP 3D-Print

World-wide first substrate holders with tilt compensation function presented by UpNano GmbH.

Vienna, Austria – A novel device allows the compensation of miniscule unevennesses in 2PP 3D-printing substrates whilst printing. The so called Substrate Tilt Frame has now been introduced internationally by the market’s innovation leader UpNano GmbH (Austria). The frame can be fitted with chuck-holders for industrial standard wafers between 2 to 6-inches. In this way 2PP 3D-printing over entire surfaces of wafers up to 4-inches with the quality UpNano’s printers are offering has now become reality. The Substrate Tilt Frame (retro-)fits any of the renown NanoOne series of laser-powered 2PP 3D-printing systems of UpNano that can build structures across 12 orders of magnitude at an unprecedented speed. Additional developments at UpNano include a fibre-holder that allows manufacturing of integrated optical systems on the tip of an optical fiber.

Being able to print structures at nanometer resolution as well as in the centimeter dimension, the NanoOne series is unparalleled on the market of laser-powered 2PP 3D-printers. It has already been used in electronics as well as in microoptics and for biocompatible applications in cell and medical research. But whatever the application, in 2PP 3D-printing size matters after all: the larger the printed structure the more the slightest unevenness of the print material will affect the precision of the final product. This well-known complication has now been addressed and solved by UpNano GmbH. The R&D department of the company with premises in the USA and Austria developed a tiltable frame that can correct an unevenness in the sub µm-range. The Substrate Tilt Frame can be extended with various holders including a series of chuck-holders for up to 6-inch wafers. Even more importantly, the entire surface of wafers up to 4-inch is now accessible for 2PP 3D-printing.

Maximum Precision

“By equipping any NanoOne printer with the Substrate Tilt Frame”, explains Denise Hirner, Head of Marketing and Business Development and co-founder of UpNano, “one maximizes the precision of the print result especially of large-scale structures.” The handy frame can be ordered separately for easy fitting to an existing NanoOne printer or as a pre-installed accessory to any new NanoOne.

The frame allows correction of substrate differences in the µm-range. Correction values are obtained by the NanoOne autofocus that takes height measurements at three points of the substrate. Based on these measurements, correction values are calculated. For the actual adjustment there are two versions of the Substrate Tilt Frame available. A competitively priced manual version that uses highly precise correction screws or an automatic version which uses software controlled precision motors for correction. The frame is compatible with all optics available for the NanoOne Series, namely the 5x, 10x, 20x and 40x objectives.

Full Circle

Whilst mounted on the NanoOne-standard long-range piezo stage with 120x100x40mm travel range the Substrate Tilt Frame allows printing excessively large areas. In fact, using the additionally available chuck-holders, this area allows for 2PP 3D-printing on the entire surface of industry standard 2-, 3-, or 4-inch wafer. A decisive advantage in the highly competitive 3D-printer market. Even on 6-inch wafers an area of 50×70 mm is available for printing. Denise Hirner comments: “The NanoOne can print at a staggering writing speed of up to 1,200 mm/s and achieves a throughput of up to 200 mm³/h. This plus the newly achieved ability to print the entire surface of an industry standard wafer of up to 4-inch makes series production with 2PP 3D-precision for the first time feasible.”

But the chuck-holders are not the only accessory that make the Substrate Tilt Frame interesting. UpNano also added a fibre-holder as well as a ferrule-holder to the portfolio. By using these holders together with a printing material with optical properties from the UpNano portfolio that has been optimized for the process, integrated optical systems can be positioned and manufactured with high precision on the tip of an optical fiber.

About UpNano GmbH (2022)
Founded in September 2018 as a spin out of the TU Wien, UpNano is a Vienna-based high-tech company with the focus on development, manufacturing and commercialization of high-resolution 3D-printing systems based on 2-photon polymerization. With the first commercial product, the printing system NanoOne, microparts with structure details ≥170 nm can be printed. Due to the very fast printing process, also meso scale parts up to several centimeters in height can be realized.
