to the AQC Exhibit Hall About the Program: Ball State University houses the Plastics Research and Education Center where plastics processing and materials testing for industry is accomplished. No other four-year school in the state addresses plastics manufacturing. No other institution in the region has the extensive laboratory facilities and equipment required to meet the varied and changing needs of the plastics industry. The center at Ball State is an active part of the BMT University Center Program effort to address the essentials needs of the regions plastics industry. About the Speakers: Dr. Wickman has selected two speakers for this year's program: "Determine
the Dimensional Stability of Stereolithography Machines and Rapid Prototyping
Resins" The objective of this study was to determine the dimensional stability of three stereolithography machines and the resins used in each. This study was conducted over a three month time span to give an indication of dimensional accuracy over time. The factors of the study were the month to month variation in the parts and the build to build accuracy of the parts. After completing this study, it was necessary to benchmark the performance of each machine in relation to their X-axis and Y-axis accuracy. This was an important parameter in the stereolithography process due to the high demand for dimensionally accurate parts. After completing this study, a greater understanding of how the factors affect dimensional accuracy of the stereolithography machines was obtained and documented. This study was sponsored by Metro Plastics Technologies, Inc., Noblesville, IN. "Nylon,
Moisture, and Zinc Stearate: A Study to Determine the Optimum Processing Window
of Glass Filled Nylon" The primary objective of this study was to determine the optimum process window for drying and micromolding glass reinforced nylon 66. In addition, a subobjective was to determine the appropriate mix ratio of the lubricant zinc stearate and glass reinforced nylon. It was the sponsor's intent that information obtained from this study would permit a reduction in scrap by allowing a process window to be developed that would eliminate flash formations and thermal degradation. Post-Meeting Follow-up: The meeting was attended by 7 Members, 4 Visitors and 12 Students. Dr. Jim Walters presented Locke and Messer with a $100 check to help finance their education. Monica Potter's name was drawn for the $161 Jackpot. Since she was not in attendance the Jackpot will grow to $168.
