Advanced Design and Manufacturing Options for Planar Light Guiding Elements Boost Printoptical Platform Capabilities

Luximprint proudly announces the availability of its advanced design and manufacturing capabilities for planar Light Guiding Elements (LGE’s). Light guiding plates, essential components in LED lighting systems, backlit displays, automotive interiors, and medical devices, have long been constrained by conventional manufacturing methods requiring expensive molds and minimum order quantities. Luximprint’s proprietary Printoptical Technology changes the game by enabling direct-from-CAD 3D printing of optically clear, functional light guides in days, not months. The enhanced capabilities include enhanced design software integration for seamless light path simulation, high-resolution micro-texturing for superior light diffusion, and scalable production from prototypes to pre-series volumes—all without post-processing, such as polishing or grinding.

Shaping and Producing Complex Light Distribution Patterns with Ease

John Gerrits, CTO at Luximprint explains: “With our advanced optical 3D printing platform for light guiding plates, we’re pushing the boundaries of optical engineering. The ability to rapidly prototype and produce complex light distribution patterns with micron-level precision directly from CAD empowers our clients to innovate without constraints. This technology isn’t just faster—it’s redefining what’s possible in light management.”

Having optical features attached to the sheet, rather than having them engraved or edged, offers new perspectives to the application and use of planar Light Guiding Elements. Whereas embedded features may transmit side-emitted light upwards, added optical features may do the opposite, boosting a much greater luminous efficacy.

Rapid Prototyping Custom Light Guides in Days

“This launch marks a pivotal evolution in additive optics fabrication,” said Marco de Visser, Co-Founder of Luximprint. “Over recent years, Printoptical Technology has significantly contributed to the transformation of rapid prototyping for custom optics worldwide. Now, with dedicated tools for light guiding plates in place, we’re unlocking new possibilities for brighter, more efficient, and creatively boundless light management solutions. Imagine iterating complex light distribution patterns in hours, not weeks—it’s a reality our clients are embracing today.”

Early adopters in the lighting and display sectors report up to 70% faster time-to-market and significant cost savings. “Luximprint’s light guiding plates allowed us to refine our automotive interior lighting prototype in record time, achieving uniform illumination we couldn’t match with injection molding,” noted a project lead from a leading European automotive supplier.

Key features of the enhanced approaches include:

• Rapid Iteration and No MOQs: Direct digital fabrication bypasses tooling investments, allowing unlimited design variations and zero minimum orders for agile development;
• Large Format Optics: with sizes ranging up to 1200*650 mm, large surfaces can be processed at once;
• Optical Excellence: surfaces are smooth and functional straight from the printer, supporting intricate microstructures that optimize light extraction and uniformity;
• Material Versatility: the light guiding features are applied on top of a substrate sheet. The material of the base sheet and its thickness may differ upon request, enabling the use of both rigid and flexible carriers, as well as different refractive indices to use;
• Design Complexity: Droplets on Demand (DOD) processing enables accurate placement of tiny light guiding apertures in any orientation, fostered by its master design;
• Shape Complexity: the light guiding elements and textures can be applied on pre-shaped substrate sheets, or can be post-processed to any freeform shape contour upon request;
• Sustainability Edge: reduced material waste and energy use compared to traditional subtractive methods, aligning with global demands for eco-friendly manufacturing.

As the demand for energy-efficient, customizable lighting surges—driven by advancements in HUD’s, IoT, AR/VR, and sustainable design—Luximprint’s platform positions itself at the forefront of the $50 billion global optics market.
