Nanoscribe introduces novel 2GL microfabrication technology

Nanoscribe, a BICO company, has introduced a novel 3D microfabrication technology – Two-Photon Grayscale Lithography (2GL). The technology merges the high resolution of Two-Photon Polymerization (2PP) with a unique, patented voxel tuning process to achieve significantly fewer printing layers – making 2GL the fastest 2PP-based 3D printing technology, with unparalleled shape accuracy and superior print quality. It paves the way for new applications, such as manufacturing even more filigree micro-optical systems with distinctly higher quality, in much shorter print times. 

3D grayscale printing is now offered as a new feature for Quantum X align.

Nanoscribe’s Quantum X platform, with its patented Two-Photon Grayscale Lithography technology for additive manufacturing of optical-grade 2D and 2.5D microstructures, is a leading solution for industrial manufacturing and mastering of micro-optics. Now, Nanoscribe has taken the voxel tuning technology to the third dimension by introducing 3D printing by 2GL as an essential addition to the Aligned Two-Photon Lithography (A2PL) features of Quantum X align.

3D printed Benchy boat split into two parts. Left part is 3D printed by 2GL. Right part is made with conventional 2PP-based 3D printing. Both parts are printed at exactly the same slicing distance, resulting in identical printing time. However, using 2GL, there are no slicing steps and the real shape of the Benchy boat is revealed, free from any voxel-related distortion.
Speed comparison of a Benchy boat 3D printed with a very competitive 2PP system (left) and with 3D printing by 2GL (right). To obtain the highest possible print quality, the slicing distance of the 2PP printed boat is set to 0.1 µm (“Fine”). In contrast, the same object is 3D printed by 2GL (“Grayscale”) with a significantly coarser slicing of 1 µm, resulting in a print time reduced by a factor of 10.

Precision and accuracy

The printing process relies on the dynamic modulation of laser power in real time while scanning at the highest speed. This results in a precise size adjustment of the polymerizing voxel to ‘perfectly’ match the contours of any 3D shape. 3D printing by 2GL guarantees flawless, optical-grade surfaces and the finest, submicron features without any slicing steps or shape distortion, just the real shape of any 3D print design.

Up to 60x higher throughput

3D printing by 2GL is one of the fastest 2PP-based microfabrication technology on the market. Its dynamic voxel tuning requires significantly fewer printing layers to achieve print results with optical-grade, smooth, and nanostructured surfaces. This translates to a manufacturing speed currently unattainable by any available 2PP-based 3D printer available – delivering 10 to 60 times the throughput of alternative 2-photon lithography system when meeting demanding print quality requirements (design dependent, compared to the same print quality).

Photonic applications

3D printing by 2GL significantly advances micro-optics manufacturing and photonics packaging. Nanoscribe’s Quantum X align with its Aligned 2-Photon Lithography A2PL is equipped with this new printing technology, supported by the nanoPrintX advanced aligner software.

Quantum X align is optimized for printing micro-optical elements with the highest placement accuracy and automatically aligned on optical fibers and photonic chips. With an entirely new level of manufacturing quality and speed, 3D printing by 2GL paves the way for advancing the industrialization of Free Space Micro-Optical Coupling (FSMOC) as a highly robust and efficient light coupling solution for photonics packaging and integration.

Temperature Sensors

  Temperature Sensors: A temperature sensor is an electronic device that measures the temperature of its environment and converts the input data into electronic data to record, monitor, or signal temperature changes. There are many different types of temperature sensors. Some temperature sensors require   direct contact   with the physical object that is being monitored (contact temperature sensors), while others indirectly measure the temperature of an object (non-contact temperature sensors).   Non-contact temperature sensors are usually infrared (IR) sensors. They remotely detect the IR energy emitted by an object and send a signal to a calibrated electronic circuit that determines the object's temperature. Among the contact temperature sensors are  thermocouples and thermistors . A thermocouple is comprised of two conductors, each made of a different type of metal, that  are joined at an end  to form a junction. When the junction is exposed to heat, a voltage is generated th

  What are Sensors, Detectors, and Transducers? Sensor/Detectors/Transducers are electrical, opto-electrical , or electronic devices composed of specialty electronics or otherwise sensitive materials , for determining if there is a presence of a particular entity or function. Many types of sensors , detectors, and transducers are available including those for detecting a physical presence such as flame , metals , leaks , levels, or gas and chemicals , among others. Some are designed to sense physical properties such as temperature, pressure, or radiation , while others can detect motion or proximity . They operate in a variety of manners depending on the application and may include electromagnetic fields, or optics, among others. Many applications over a wide range of industries use sensors, detectors, and transducers of many kinds to test, measure, and control various processes and machine functions. With the advent of the  Internet of Things (IoT) , the need for sensors as a pr
