The Ultra High-Definition LRS-4KA UV projector provides an outstanding combination of advanced DLP™ electronics and high-performance optics.  Using Texas Instruments’ latest DLP660TE ™ DMD, this projector can display over 8 million pixels using a high-power LED source.    Combined with dedicated UV optics and high-power UV LEDs, the LRS-4KA makes high-speed 3D manufacturing possible.

Designed specifically for stationary high-resolution stereolithography applications, the LRS-4KA will be a core element of the next generation of 3D printers.  By providing complete control of an integrated optical actuator, you can address 8.3 million unique pixel locations, enabling the manufacturing of extremely high-resolution parts.

The system comprises a UV-optimized optical system and a selection of different UV LED light sources with an optical output power of up to 4.5 watts.    The projector features a high-performance optical assembly from Visitech and is available with three different projection lens magnifications: 13x, 14x, or 17x.  The magnification of these lenses can be adjusted, allowing pixel sizes from 60 to 100-micron pixels, supporting build areas from 163 x 92 mm up to 272 x 153 mm, and feature sizes as small as 30 microns.

LRS-4KA 4K UV Projector

3 configurations:

  • LRS-4KAp: High Performance version providing up to 4.5 W
  • LRS-4KAc:  Standard version providing up to 2.5 W
  • LRS-WQm:  Similar to the LRS-4KAc, but without an optical actuator (>4 M Pixel resolution)

The LRS-4KA comes in three configurations enabling  an advanced and extremely competitive plug-and-play projector.  This flexibility allows customers to design, build and brand a Rapid Manufacturing machine with a very short time-to-market and with very low technical risk.  And using Texas Instruments’ reliable DLP660TE DMD technology, the DLP660TE DMD projector offers a long lifetime at a competitive cost.

Note:  This product line is specifically designed for static implementations in additive manufacturing systems.
