Optical Liquid Silicone Rubber Introduced at Proto Labs
Injection-molded optical LSR shines new light into product development possibilities
MAPLE PLAIN, Minn.--Rapid prototyping and low-volume manufacturer Proto Labs, Inc. (NYSE:PRLB) has added optical-grade liquid silicone rubber (LSR) to its existing lineup of moldable plastic, metal and LSR materials. High-performance optical LSR is transparent, extremely flexible and starting to replace glass in many optical applications.
The engineering-grade thermoset offers a host of benefits for those developing components and products inside the lighting industry. Optical LSR does not discolor or lose transparency with age or with exposure to heat or UV light; it is significantly lighter than glass and most other plastics; and it is scratch and crack resistant, among many other advantages.
"One of the more exciting aspects that optical silicone presents to a designer is its ability to reduce the bill of materials in a final assembly," explains Jeff Schipper, Proto Labs product manager for LSR. "In a lighting application, for example, you have a lens and seal that would traditionally be two parts. With optical LSR, you can combined the two into a single part, which reduces cost and overall inventory."
Proto Labs will be in Las Vegas this week (Feb. 24-26) at the Strategies in Light conference discussing optical LSR along with its other quick-turn injection molding, CNC machining and 3D printing capabilities.

Featured Product
3D Vision: Ensenso B now also available as a mono version!
This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
