Design Considerations for Mask Projection Microstereolithography Systems
نویسندگان
چکیده
Mask projection microstereolithography (MPμSL) uses a dynamic mask and focusing optics to digitally pattern UV light and selectively cure entire layers of photopolymer resin. These systems have been shown to be capable of creating parts with features smaller than 10μm. In this paper, the authors analyze existing MPμSL systems using functional decomposition. Within the context of a morphological matrix, these systems’ design embodiment decisions are compared and the resulting performance tradeoffs are quantified. These embodiment decisions include the dynamic mask, UV light source, projection orientation, and supporting optics. The aim of this work is to provide a design guide for the realization of future MPμSL systems.

Multimaterial 4D Printing with Tailorable Shape Memory Polymers
We present a new 4D printing approach that can create high resolution (up to a few microns), multimaterial shape memory polymer (SMP) architectures. The approach is based on high resolution projection microstereolithography (PμSL) and uses a family of photo-curable methacrylate based copolymer networks. We designed the constituents and compositions to exhibit desired thermomechanical behavior (...

متن کاملA CP Mask Development Methodology for MCC Systems
The character projection (CP) is utilized for maskless lithography and is a potential for the future photomask manufacture because the CP can project ICs faster than the point beam projection and the variable-shaped beam (VSB) projection. The drawback of the CP is its lower throughput than that of photomask-based lithography and the amortization cost of CP equipment leads to the price rise of I...

Solid freeform fabrication (SFF) processes based on mask image projection such as digital micro-mirror devices (DMD) have the potential to be fast and inexpensive. More and more research and commercial systems have been developed based on such digital devices. However, a digital light processing (DLP) projector based on DMD has limited resolution and certain image blurring. In order to use a DL...
