Nanoscribe – Quantum X align

Highest resolution 3D printer with A2PL® technology for nanoprecise alignment

The Aligned 2-Photon Lithography (A2PL®) system Quantum X align enhances Nanoscribe’s field-proven 3D Microfabrication technology based on Two-Photon Polymerization (2PP) by adding high-precision alignment capabilities for highly accurate placement of printed structures. With A2PL freeform microoptics can be printed precisely aligned to the optical axes of fibers or photonic chips with submicron accuracy using this highest resolution 3D printer with nanoprecision aligned 3D printing capabilities. Produce efficient optical interconnects for photonic integration and photonics packaging or miniaturized imaging optics, e.g. for minimally invasive endoscopy.

1. Scene printing

nanoPrintX is a print project development software based on scene graphs. With this modern, tree-like data structure, you can easily generate logical relationships between elements of the print and assign individual properties or print parameters. This allows you to exactly define how the printed structures are aligned to the substrate and to each other.

Load multiple CAD designs into one scene and assign different print parameters to each part design. This way, you can fine-tune your print and obtain optimized quality and speed for each section. Many actions can be dynamically configured using drag & drop. For example, you can easily change the order of alignment and printing operations.

2. On-fiber printing

With nanoPrintX you can design your individual Lensed Fiber Arrays (LFAs) in just a few steps.

Select the fiber node in the scene graph and place your individual lens designs as .STL or .OBJ files on the fiber. With just a few steps you can easily generate multiple copies of the same print or customize each fiber with an individual design.

3. nanoConnectX

Control and monitor the system with nanoConnectX, the remote access software for the Quantum X platform. It guides you to a successful print in just a few steps.

Select your print project, register the starting position and start printing. The system then automatically aligns and prints the structures in exactly the right position and spatial orientation.
