High power static stacked configurationStatic systems

The most compact WQXGA
additive manufacturing light engine


When pixel size and dimensional accuracy of your smaller printed parts matter, the LRS-Compact’s high native pixel resolution of 4 million pixels truly shines. Depending on your wavelength and cost targets, DMD options with 2716 x 1528 or 2716 x 1600 resolutions are available. When you need larger build area sizes, the LRS-Compact offers stackability from 60 micron pixel pitch upwards.

Providing easy and seamless integration with machine control software, the LAMA SW eliminates downturns and compromises from USB and video interfacing, such as HDMI or DisplayPort.

STACKING: Combine the outputs for larger builds

The LRS-Compact is well-suited for stacking in a static configuration. The 60 micron (and up) native build field pixel pitch ensures that the combined light engines achieve a smooth surface finish and is a cost-efficient solution to increase your print productivity for large build field areas.

High resolution

With more than 8 million addressable pixel positions, the DLP®-based stereolithography subsystem is explicitly designed for static implementations in 3D printing and additive manufacturing systems, producing the highest resolution parts.


Achieving unit-to-unit consistency between light engines can be challenging, especially in cost-conscious market segments. To ensure consistency, the LRS-Compact Series features extensive and detailed product characterization and calibration.

NEOS platform benefits

Being the world’s smallest WQXGA DLP light engine for AM is not the only benefit of the LRS-Compact Series. Advantages of the NEOS platform on which it is built include advanced and functional mechanical design – fully aligned with the NEOS design language. The LRS-Compact Series comes with an encapsulated optical core and meets the robustness demands of the 24/7 additive manufacturing world, where more demanding operation schemes may leave bygone rapid prototyping tech struggling.

Further cross-platform features include standardization on industrial-grade Ethernet for communication and data transfer and liquid cooling as the preferred thermal control for maximum power and performance.

Optimal performance

Visitech’s proprietary Bifrost S LED light source (5th and 6th generation) features advanced power output and optimal performance. The LRS-Compact Series comes with the AM-optimized and fully integrated LAMA Standard software base.
