IN-VISION’s native 4K Light Engine enhances UV light projection for advanced 3D printing & lithography applications

IN-VISION Technologies AG, a developer of high-precision optical systems for industrial applications, launches a high performance system that would bring UV light projection to a new level for advanced 3D-printing and lithography applications.

Described as the world’s first native 4K Light Engine, the AVATAR high performance system would be the next step in DLP-Projection.

Until today, 4K in DLP-Projection was usually achieved by re-positioning WGXGA-Chip pixels to improve image resolution. This method increased resolution but image size was unchanged. The new chipset from Texas Instruments, due for release mid- 2022, introduces a radical improvement: it offers a “native” resolution of 4096×2176. As a Texas Instruments Design House partner, IN-VISION is developing the first industrial UV Light Projector based on this chipset. AVATAR enables users of 3D-printing and lithography to expose, at high resolution, a larger area than previously possible, and to make moving exposures with high optical performance, the company says in a press release.

Some of the main features of the flagship-system will be:

  • Open System: The built-in Xilinx Zynq UltraScale allows users to customize their applications or use prepared Software.
  • Field Changeability: The LED-Module is easily swapped out by the customer and does not require any further calibration or set-up.
  • Scrolling availability: AVATAR is designed for moving exposure. It comes with an optical PCIe-Interface, Optical Trigger IN/OUT and a 1 Gigabyte Ethernet-Connection to ensure high scrolling speeds.
  • Watercooled System: Illumination- and DMD-Units are equipped with separate connectors for water cooling to achieve optical peak system performance .
  • Stackability: The small width of the system allows projectors to be lined up down to very small pixel sizes – Onboard User-Interface: An OLED-Display informs the user about the operating status and key parameters.
  • Designed for performance: To handle the large amounts of data that a 4K image contains, especially in scrolling mode, the device is equipped with an optical PCIe interface.

AVATAR is an exciting development,” says Christof Hieger, In-Vision CTO, “the new projection system redefines the boundaries of DLP technology in Additive Manufacturing and lithography”.

CEO Florian Zangerl explains: “First Pre-Series Models of the next-generation Light Engine will be available for Lead Customers in the fourth quarter of 2022”.

Serial production of AVATAR is expected for 2023. IN-VISION’s Lead-Customer-Program closes soon, but minor adaptions can still be taken into account.
