Carbon has announced the launch of the L1 Digital Light Synthesis system. The L1 is available as a limited release as part of Carbon High-Volume Solutions, built to launch industry-transforming products to high volume immediately.

The L1 is said to provide 10x the build area of Carbon's first printer, the M1, and five times the M2 (189 x 118 x 326 mm). That makes it better suited to both larger size parts as well as for printing many parts simultaneously at scale.

L1 - Digital - Light - Synthesis - System

Currently the L1 Digital Light Synthesis system is already in the hands of Adidas and Riddell. Adidas has been using the new machines to help produce 100,000 pairs of the Futurecraft 4D midsoles in 2018, and plans to scale the production of the Futurecraft 4D shoes to millions in the coming years. Meanwhile, new customer Riddell is using it to 3D print customised helmet liners within its SpeedFlex Precision Diamond helmet model, used by select NFL players in the 2018 season. The customised helmets will be commercially available on a limited basis at the 'elite level' starting in 2019.

Riddell - Application - L1 - Platform - Companies

In Riddell’s application of the L1 platform, the two companies have partnered to 3D print customized helmet liner precisely contoured to the athlete’s head. Powered by Carbon, Riddell’s new Diamond helmet platform features a 3D printed lattice liner that is digitally manufactured using Carbon’s proprietary Digital Light Synthesis (DLS) technology.

The core technology uses a custom designed, highly damping elastomer from Carbon, in the form of a lattice structure to create the helmet liner. The Carbon Lattice Engine leverages physical simulation and optimization techniques to tune structures to further manage both linear and rotational impact energies. Each helmet is made up of more than 140,000 individual...
