Superior resolution light engine
The LUXBEAM® Rapid System LRS-4KA AC is designed explicitly for static implementations in 3D printing and additive manufacturing systems. With more than 8 million addressable pixel positions, the 4KA is the superior resolution light engine.

– ideal for static use in 3D printing
Power and throughput
The LRS-4KA projector subsystem makes UV optics, hardware, and software work together to deliver high power and throughput in an easy-to-use, reliable package. Customizing wavelength and projection lens assembly for individual system requirements gives you flexibility.
Designed explicitly for static implementations in 3D printing and additive manufacturing systems, the LRS-4KA is a superior resolution DLP®-based stereolithography subsystem. With more than 8 million addressable pixel positions, it enables the production of the highest resolution parts.
LRS-4KA AC: Compact versatility
The air-cooled LRS-4KA variants achieve superior 4K resolution from the most compact light engine cabinet, allowing implementation into even desktop- and compact standalone machines. With Visitech’s extensive range of projection lenses, any need is covered – from static micro-SLA to large formats (up to A4 size). As a result, this is a highly compact and cost-efficient solution for a wide range of additive manufacturing systems.
Choose your performance level
Three product performance levels are available: The air-cooled commodity version for cost-sensitive systems, an air-cooled version for high-power systems, and the extreme performance, liquid-cooled LRS-4KA LC.
Full pixel sequence control (FSPC mode) explained
The advanced LC4KA-EKT controller of the LRS-4KA projector provides complete control of the data content in the projected subframes, with three valuable advantages:
No re-sampling errors
The controller uses the exact native resolution of the DMD, which allows pixel-pure exposures. This differs from systems using the original DMD reference controller, designed for UHD video inputs, but requiring data re-sampling. Re-sampling causes unwanted pixel errors due to input resolution mismatch between the controller and the DMD.
Complete control of the optical actuator
You can control both actuator positions timewise on every layer and apply an image offset of 1/2 pixel to generate a better resolution of outer contours in each layer, resulting in a better surface finish of the printed objects.
Flexible architecture for simple and easy integration with your machine design.
The LC4KA-EKT controller’s Full Pixel Sequence Control (FPSC) mode avoids re-sampling errors and gives you complete control of the projector’s image information. The result is a superior finish.
A slim footprint allows for stacked configurations, yielding 8K, 16K, and higher resolutions. Up to 7W of optical power output makes it the most compact high-power 4K projector at hand.
