10:30 a.m. – 11:30 a.m. A Research and Industry Roadmap: Barriers and Opportunities for Increased, Lower Cost Additive Manufacturing Integration for Investment Casting Foundries Christopher Annear, Penn State Behrend, Paul C. Lynch, Penn State Behrend Additive manufacturing techniques have revolutionized
the investment casting industry over the last decade. The fabrication of patterns using an additive technique has proven an effective way to significantly reduce the lead time and cost of low-volume investment castings in a way that can be easily integrated into many existing foundry processes. However, many existing foundries still have not made the capital investment to implement these technologies in-house and are outsourcing the patternmaking to job shops that specialize in additive manufacturing. This paper builds off of recently completed research with lower cost additive manufacturing systems and design to detail a cost- effective way to begin integrating this technology directly into investment casting foundries while outlining some of the open research topics to be explored for increased and optimal low cost additive manufacturing integration.
11:30 a.m. – 12:15 p.m. How Is My Pattern Coating and Draining? Gavin Dooley, REMET UK, Booth 101 A novel method of studying the rheological behavior
of ceramic slurries for investment casting using the three interval thixotropy test (3ITT) technique is being used for the first time to determine the effect of instant shear on the structural deformation and recovery of slurries. The technique is of potential importance in the investment casting industry and could be used to fingerprint different

types of slurries based on their rheological characteristics. In this study, several investment casting slurry products were instantly deformed with predetermined levels of shear stress and shear rate which attempt to simulate forces at play during application of a slurry onto a wax pattern. The 3ITT data revealed that the applied instant
shear resulted in deformation of the slurry samples to different extents depending on slurry type, shown by their deformation which in turn resulted in different durations required for structural recovery. In conclusion, the results demonstrated that 3ITT is an
effective method for the collection of data on deformation and structural recovery kinetics of investment casting slurries, and therefore is an effective tool for simulating and analyzing the effects of the handling, stirring, and dipping steps relevant to the application of investment casting slurries onto wax patterns.

engineering programs is typically very limited if existent at all. A new competition with a new model has emerged where students interact directly with foundries as part of the process. This paper describes that process along with the benefits for students and companies involved.
1:30 p.m. – 2:30 p.m. Water Shell Removal Compared to Other Methods Darrell Terpenning, NLB Corp. Booth 216 Removing ceramic
shells from investment castings
without damaging the part can be a challenge, especially when high rates of productivity are demanded. Various methods are commonly used, and each has advantages and disadvantages. This white paper compares water jetting to the other methods and explores the key factors to evaluate when considering water jetting.
