Design Considerations for Mask Projection Microstereolithography Systems
(University of Texas at Austin, 2013) Lambert, Phillip M.; Campaigne, Earl A. III; Williams, Christopher B.
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.
Design, Developments, and Results from the NIST Additive Manufacturing Metrology Testbed (AMMT)
(University of Texas at Austin, 2016) Lane, B.; Mekhontsev, S.; Grantham, S.; Vlasea, M.L.; Whiting, J.; Yeung, H.; Fox, J.; Zarobila, C.; Neira, J.; McGlauflin, M.; Hanssen, L.; Moylan, S.; Donmez, A.; Rice, J.
The National Institute of Standards and Technology (NIST) is developing a facility titled the Additive Manufacturing Metrology Testbed that will enable advanced research into monitoring, controls, process development, and temperature measurement for laser powder bed fusion additive manufacturing and similar processes. This system provides an open control architecture as well as a plethora of sensor systems and calibration sources that are primarily radiance-based and aligned co-axially with the laser beam and focused on the laser interaction zone. This paper briefly reviews the system requirements, and details the current progress of the facility design and construction. Mechanical, optical, and control systems designs are detailed with select highlights that may be relevant to additive manufacturing researchers and system developers. Recent experimental results from the prototype laser control and in-situ monitoring system are also highlighted.
