Lithography-Based Additive Manufacturing: Micrometric Precision in 3D Printed Biocompatible Polymers and Metals
Abstract
Lithography-based additive manufacturing (LBAM) merges the precision of photolithography with the design flexibility of 3D printing. By formulating feedstocks and developing UV exposure strategies, we have achieved micrometric feature resolutions across various materials.
Leveraging CSEM’s expertise in biology, fluidic systems, and additive manufacturing, we developed a high-resolution stereolithography platform for biocompatible fluid-handling systems. This platform produces monolithic devices with embedded microchannels, ideal for medium handling at different scales, up to standard well-plate formats. We also developed integrated actuation with membrane valves to further expands our approach utility for precise small-volume liquid management.
Beyond polymer-based applications, we have extended LBAM to metal and ceramic components using a sinter-based process. This approach enables the production of complex geometries that are challenging or impossible to achieve with conventional manufacturing techniques. It is particularly valuable for industries requiring high-strength, wear-resistant parts, utilizing biocompatible metals such as 316L stainless steel and Ti64 titanium alloy.
Together, these advancements demonstrate the versatility of LBAM in delivering high-resolution, complex parts while offering diverse material options tailored to the needs of biotech and medtech industries.

Bio
I am a materials scientist dedicated to pioneering innovative manufacturing methods. I earned my Ph.D. at EMPA, where I developed polymer templating strategies to fabricate thin-film photoelectrodes inspired by moth-eye architectures for solar water splitting. During my postdoctoral work at EPFL, I honed my process development skills by employing spray pyrolysis techniques to create complex thin-film materials, with a focus on synthesizing novel ternary oxides. For the past four years as a senior R&D engineer at CSEM, I have led the advancement of high-resolution additive manufacturing of polymer using UV-stereolithography, delivering solutions for the watch industry and life sciences. Today, I spearhead projects to develop lithography-based platforms for printing metals and ceramics, demonstrating how advanced materials science can drive innovation across diverse technological fields.
