Vat mode

For the production of taller structures, NanoOne offers a unique vat mode that enables the fabrication of large objects with a height of up to 40 mm. In this mode, a vat with a precision glass window is positioned above the objective, preventing resin contact and preserving the focusing power of the objectives. The element is printed layer by layer, with the object being drawn up out of the resin vat while maintaining a constant distance between the current print layer and the objective. This approach ensures consistently high precision throughout the printing process, guaranteeing optimal printing conditions and precise results. It is the preferred printing mode for producing high-quality, large micro-components.

Bottom-up mode

The bottom-up mode provides an effective solution for producing flat structural elements and enables the direct manufacturing of high-resolution structures within a substrate. In this mode, the laser beam is focused through the high-precision glass bottom of the substrate, allowing the structure to be built from the bottom to the highest point of the geometry. Throughout the printing process, the distance between the objective and the build platform gradually decreases. Potential substrates suitable for this printing mode include well plates, petri dishes and microfluidic chips.

Top-down mode

Similar to the bottom-up approach, resin is applied to or within a chosen substrate. However, the difference lies in the initiation point of printing, which starts at the top of the geometry instead of the bottom. This method prevents objects from being printed through already polymerized resin, ensuring no loss of resolution throughout the printing process as the distance between the objective and the build platform gradually increases. While this print mode presents several advantages, it is limited to certain resins with higher viscosity or when using pre-coated substrates.
