Abstract Scope |
This work details the design and fabrication of a large-volume stereolithography printer that is capable of printing structures over one foot per dimension out of high-viscosity, paste-like elastomeric resins as well as low-reactivity resins that need orders of magnitude greater exposures of light to cure than traditional SLA resins. We present a detailed overview of the printer design and capabilities including a novel method of recoating high-viscosity resins for SLA and a roll-to-roll film tensioning technique to greatly reduce the separation force experienced by the printed structure between each layer. We also describe the scaling up of a recently reported novel light-patterning technique that can pattern high-intensity UV light over areas exceeding one foot per dimension with 8K resolution. |
