By Light Alone - The Next Generation of Fabricating 3D Electronics at a Mass Manufactured Scale

One of the 'Holy Grails' of Additive Manufacturing is creating mixed metal and polymer composite objects at a scale and cost that goes beyond prototyping and directly competes with existing industry techniques. Our startup MAASS has developed a revolutionary solid-state manufacturing approach that eliminates all moving parts and contact-based processes, combining digital light projection, laser machining, and nano-ink metallization. Unlike traditional methods requiring inkjet printheads, physical masks, or contact-based tools, our system relies entirely on stationary optical and laser systems, enabling exceptional reliability and unprecedented material versatility. The process employs direct light projection and engineering resins with our patented material switching technology to create multi-polymer structures, while precision fiber lasers micro-machine and bond metal films enhanced by nano-inks. This robust, solid-state approach processes an extensive range of materials - from high-performance polymers to specialized metals - fabricating precision electronic components within complex structures at speeds and costs competitive with traditional manufacturing, but without the mechanical complexity and wear inherent to conventional methods
