“3D PRINTED LED OPTICS: STRAIGHT FROM THE PRINTER WITH ONLY ONE STEP FROM CAD-TO-OPTIC”
LUXeXceL Group, a company having it’s head quarters and technology center in Goes, Netherlands, offers services for Optics Design and Additive Manufacturing of LED Optics. The process – called ‘Printoptical Technology’ – 3D prints optical structures and elements using modified wide format industrial inkjet equipment.
Jetting and Curing
Transparent droplets of a UV-curable polymer are jetted and then cured by strong UV-lamps which are integrated onto the print head. The results of the printoptical process are geometric or freeform shapes that may include transparent prisms or lenses, as well as full color 3D graphics and textures, all in a single print job.
Droplets on Demand
The key element of the Printoptical Technology is the piezoelectric controllable print head, which provides a resolution of 1,440 dpi or greater. Even though the material is deposited in discrete drops, the resulting surface is smooth. This is accomplished by delaying the time between the jetting of the droplets and the application of UV light, which gives the polymer time to flow and for each droplet to lose its spherical form.
Optical surfaces – no post-processing
The results of the process are geometric or freeform shapes that may include transparent prisms or lenses, as well as full color 3D graphics and textures. Optical quality surfaces are achieved with no post processing. Printoptical Technology avoids complicated and costly conventional processes, gets rid of obsolete stock and shortens the time to market significantly.
