Technology & Products
Key Products
4D-printed vascular stents using projection micro-stereolithography (PµSL) for coronary artery applications.
Technological Advantage
Proprietary micro stereolithography 4D printing process for adaptive stents, with research published in Advanced Functional Materials (2026).
Differentiation
Value Proposition
Reduces stent deployment risks by eliminating external heating, enabling safer and more efficient vascular procedures with natural expansion at body temperature.
How They Differentiate
Focus on 4D-printed medical stents with low-temperature activation vs. broader AM research labs; proprietary micro stereolithography for precise, biocompatible structures.
