Abstract

Multi-material micro-nano-printing advances 3D additive fabrication towards true functional printing. Ultimately, full 3D digital fabrication searches full control over each individual atom. A polymer printing process that comes closest to this is 2-photon direct 3D laser writing. Multi-material printing has three challenges: materials, tools, and scalable processes. The material spectrum is continuously growing. Faster and more scalable processes will come from academic push and industrial pull. We contribute a novel material exchange process for 2-photon laser writers. Our in-situ material replacement exchanges printing material completely with fresh ones.
