Cost-effective 3D printing performance
For the cost-sensitive desktop 3D print industries, the LRS-Compact Series is essential to achieving superior quality and performance at a competitive cost. The DLP®–based stereolithography subsystem delivers high resolution with 4 million native pixels and implements productivity in its target market segments: Compact professional desktop and stand-alone additive manufacturing systems.
Recommended use
The most compact WQXGA
additive manufacturing light engine
LRS-COMPACT PLUS
The LRS-Compact Plus gives you more addressable pixels and more productivity. You can create larger and finer prints faster with 8 million addressable pixels (3480 x 2160).
The high power output and increased power density reduce layer exposure time, even on large-build platforms.
Cost-concerned? The LRS-Compact Plus is remarkably cost-efficient, with long-lasting LED and free LAMA software that lets you choose between two actuator schemes (Texas Instruments’ original XPR or Visitech’s proprietary FPSC) to customize your power and exposure settings for the four subframes. The LRS-Compact Plus is the ultimate subsystem for highly productive additive manufacturing.
The LAMA SW eliminates downturns and compromises from USB and video interfacing, such as HDMI or DisplayPort, providing easy and seamless integration with machine control software.
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.
Consistency
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.
Full pixel sequence control (FPSC mode) explained
The advanced LB6600 controller of the LRS-Compact Plus projector provides full control of the data content in the projected subframes, yielding 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, which was designed for UHD video inputs but requires data re-sampling. Re-sampling causes unwanted pixel errors due to a mismatch between the controller and the DMD.
Complete control of the optical actuator
You can control 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.
