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 LRS-4KA is the superior-resolution light engine.
*End-of-life product
Recommended use
Maximum power for static 3D print systems
Power and throughput
The LRS-4KA projector subsystem integrates UV optics, hardware, and software to deliver high power and throughput in an easy-to-use, reliable package. Customizing the wavelength and projection lens assembly for individual system requirements gives you flexibility.
Highest resolution projector
Designed specifically 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 deliver superior 4K resolution in the most compact light engine cabinet, enabling 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, the air-cooled version for high-power systems, and the extreme-performance, liquid-cooled LRS-4KA LC.
Full pixel sequence control (FPSC mode) explained
The advanced LC4KA-EKT controller of the LRS-4KA projector provides complete control over the data content in the projected subframes, with three valuable advantages:
No re-sampling errors
The controller uses the DMD’s native resolution, enabling pixel-pure exposures. This differs from systems using the original DMD reference controller, designed for UHD video inputs and requiring data re-sampling. Re-sampling causes unwanted pixel errors due to mismatch between the controller and the DMD’s input resolutions.
Complete control of the optical actuator
You can control both actuator positions time-wise on every layer and apply an image offset of 1/2 pixel to improve the resolution of outer contours in each layer, resulting in a smoother surface finish of the printed objects.
Fleixble architecture
Flexible architecture for simple and easy integration with your machine design.
Advanced controller
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.
Stacking possible
A slim footprint enables stacked configurations, supporting 8K, 16K, and higher resolutions. Up to 7W of optical power output makes it the most compact high-power 4K projector available.
