Polymer Composition and 3D-Printer for Stereolithography
- 詳細技術說明
- This invention allows for the rapid fabrication ofhigh-resolution silicone (polydimethylsiloxane) based elastomeric devices viastereolithography.
- *Abstract
-
A range of stereolithographicresins have been synthesized allowing for 3D printing of highly-flexibleelastomeric devices. Modification of the build window allows highertransmission of low wavelength/high energy UV light, permitting greaterversatility in the photopolymerization process. This technology greatly expands thecapabilities of stereolithographic 3D printing allowing for the cured materialto have a broad range of elastic moduli, toughness, and elongation.
Unlikeepoxies and acrylates, these highly chemically-stable silicone based precursorsallow for scalable micron resolution printing of polymers which remains flexibleat room temperature.
Potential Applications
· 3D printing/Additive manufacturing
· Soft robotics
· Medical device fabrication
Advantages
· Tunable Young’s moduli, 5kPa < E <300 kPa
· Ultimate elongations(γ)between 0.5 and 4.5
· Excellent resilience and fatigue resistance
· Rapid photopolymerization and build time
· more intricate architectures can be obtained compared to soft(stamp) lithography.
· Free form fabrication of 3D objects with micron sizedfeatures.
· Eliminatespost-processing thermal treatment needed in elastomeric polyurethanes
