Impression 3D sans solvant d'élastomères en silicone par traitement numérique de la lumière utilisant un bis(acyl)phosphane oxydé substitué par un oligosiloxane comme photoinitiateur

Key Points

• To explore the fabrication of silicone elastomers using solvent-free 3D printing and a novel photoinitiator.
• Developed a photoinitiator based on oligosiloxanyl substituted bis(acyl)phosphane oxide.
• Utilized digital light processing for 3D printing.
• Fabricated silicone elastomer structures using poly(dimethylsiloxane) formulations.
• Successfully printed complex 3D structures without solvents.
• Demonstrated the material's applicability in biomedical and soft robotics fields.
