Speed, resolution, and build area for powder bed fusion

The LUXBEAM® Rapid System LRS-MCx WX NIR removes the traditional limitations of polymer-based powder bed fusion (PBF). With unprecedented near-infrared power and flexible static or scrolling arrangement options, the subsystem opens new doors for high-throughput, high-resolution additive manufacturing using PBF.

Maximum throughput
in powder bed fusion

Visitech introduces the LRS-MCx WX NIR light engine, providing unprecedented near-infrared power of more than 100 W in the projected 2D image. For polymer-based powder bed fusion (PBF), the subsystem offers a path toward high productivity systems.

An alternative to classical selective laser sintering (SLS) technologies – where the polymer material is heated up sequentially, point-by-point, and layer-by-layer, the LUXBEAM® Rapid System LRS-MCx WX NIR rationalizes toward a pure layer-by-layer approach, with instant 2D imaging.

Direct Image Sintering (DIS): The new PBF method

Visitech’s new DIS concept uses DLP and powerful IR laser diode arrays to substantially increase print speed, resolution, and build area over traditional polymer PBF methods. Exposing the entire print layer in one shot is the critical driver of build speed.

Applying Visitech’s scrolling subsystem, stacking multiple, powerful IR light engines in a motion stage that scrolls them over a vast build area, effectively removes established polymer-based PBF limitations.

With the DIS concept’s ability to maintain high resolution across the build area, a world of opportunities opens for innovative system builders seeking actual mass production capabilities for their polymer powder bed fusion systems.

Accelerating powder bed fusion

The liquid-cooled LRS-MCx WX NIR modules offer stackability for stitched images in static, step-and-flash, or scrolling configurations. For single-pass linear motion systems, this enables the highest manufacturing throughput.

In addition, alignment features grant pixel-precise alignment of the modules. Featuring the highly robust and reliable high-resolution DLP650LNIR WXGA chipset, the system operates with an external, fiber-coupled NIR laser in the 800-1200 nm range.

Unique light source

The LRS-MCx WX NIR light engine comprises a proprietary integrated laser diode module for maximum control in throughput, safeguarding system components such as the DMD at their best – for static or dynamic implementations.

Advanced controller

The LAMA STANDARD software package and API allow you to choose any motion controller in their basic configuration for the LRS-MCx WX NIR. 10G bandwidth even allows streaming. For advanced users, the LAMA PRO software version allows advanced operation modes, including subpixelation (improved surface finish) and edge blending for perfect stitching. However, achieving maximum performance and complete functionality requires a dedicated motion controller configuration.

Enlarging the build area

While introducing multihead scrolling as the most advanced solution for scaling up 3D print stereolithography system productivity, Visitech adds a plug-and-play reference stage to its portfolio. Implementing scalable motion systems allows for enlarged build areas. It is designated for expert static 3D print machine developers and manufacturers, who will find that the improved productivity th LRS-MCx motion stage opens for new business opportunity exploration.

Flexible motion stage platform

Designed for installation in bottom-up and top-down configurations, the motion stage rooms up to four LRS-MCx photoheads. A wide projection lens selection enables various configuration options, allowing for seamless stitching of native images – with pixel pitch as small as 50 microns. The flexible platform of the motion stage is suitable for UV stereolithography and works equally well in polymer-based powder bed fusion installations.
