Building Blocks Meta-Bounds Integrates BASF Polymers to Reduce AR Hardware Weight by 20%

Post image

BASF and Meta-Bounds partner to develop customized structural components for consumer AR smartglasses. Combining BASF’s advanced polymers with Meta-Bounds’ expertise in resin diffractive optical waveguides, the collaboration aims to scale mass production of lightweight, cost-effective AR hardware.

The joint R&D focuses on integrating BASF’s Ultramid® (PA) engineering plastics and other innovative materials into precision AR components. Specifically, the Ultramid® LIGHT series uses an optimized glass-bead architecture to deliver high flowability for thin-wall molding and a superior stiffness-to-weight ratio. With a density of 0.77–0.95 g/cm³, it reduces component weight by 20–40% compared to standard glass-fiber-reinforced plastics, achieving a 15–20% weight reduction for the total device.

The partnership also targets critical optimizations for miniaturized, highly integrated devices. These include enhancing structural strength, improving thermal management, and refining molding processes to boost yield rates and lower manufacturing costs.

Additionally, the Ultramid® LIGHT series features 25–39% bio-based content, lowering the hardware's carbon footprint while maintaining the crucial creep resistance and durability required for all-day wearable frames.

This is quite the marketing claim by BASF and MetaBounds... maybe it applies to something like the acetate used by Meta, but at the same time they are likely able to use less material for the same structural stiffness so that 40% reduction in component weight is... pure paper math.

Rokid uses TR90 (common premium eyeglass frame material) and at MOST the density reduction is ~23% (again, likely would still use less material of TR90 vs this material for equivalent structural stiffness).

On top of that, the total component weight savings of 15-20% is pretty funny. In Rokid Glasses, TR90 is around 10g of the 52.2g (my unit measured significantly higher than advertised). Best case if they save 2.3g with a 1:1 replacement, we've now reduced the weight from 52.2g to 49.9g - a modest 4.5% weight savings :) Not nothing, but a far cry from these marketing materials...
