1:55 p.m. - 2:30 p.m. Paper No. 13 Development of Silica Based Photopolymer Materials for 3D Printing in Investment Casting Applications Vincent Icart, Prodways & Ann Kutsch, Tethon 3D This paper aims to present technical developments of a


silica investment casting loaded photocurable slurry for use on top-down DLP printing. It aims to present the specific formulation considerations that were considered to make the chemistry compatible for use in investment casting applications, including single crystal casting of cores. The paper will cover: • UV curing behavior Maintaining XY resolution even though particulates scatter light


• Reasonable cure depth and energy dose to manufacture parts at acceptable productivity levels


• Favorable flow behavior Recoating on top-down printing systems


• Settling behavior How the slurry was engineered to allow large volumes into vats, without the need for constant stirring while printing


• Mechanical properties Specific developments to allow green parts manipulation as well as withstanding the waxing and casting processes


• Optimization of cleaning process • Leachability Densification control and formulation to allow proper leaching out of the parts


• Independent testing by LBBC • Surface finish characterization on fired ceramics samples


• Validation of printed parts by computed tomography Keywords: Additive Manufacturing & 3D

8:00 a.m. - 8:10 a.m. GREETING


8:10 a.m. - 8:50 a.m. Paper No. 14 Enhancing Manufacturing Processes: Investment Casting Meets 3D Printing Eric Yeung, Stratasys Investment casting is a tried-and-true method for


creating intricate and complex metal parts. But the combination of investment casting and 3D printing using stereolithography is opening up new possibilities and advantages for manufacturers. In this presentation, you'll gain invaluable insights into


the benefits of adopting 3D printed patterns over traditional production methods and learn how to overcome the pitfalls associated with investment casting. 1. The Advantages and Limitations: Understand the unique advantages that result from combining investment casting and 3D printing.


2. Ideal Applications for 3D Printed Patterns: Discover the industries and applications where 3D printed patterns truly shine.


3. Designing with Stereolithography: Learn the intricacies of designing 3D printed patterns using stereolithography. The presentation is ideal for engineers, designers,


manufacturers, and anyone involved in the investment casting process who wants to stay ahead in the rapidly evolving manufacturing landscape. Whether you're already familiar with 3D printing or just beginning to explore its potential, this presentation offers something for everyone. Keywords: Rapid Prototyping


8:50 a.m. - 9:30 a.m. Paper No. 15 Advances in 3D Printed Patterns for Investment Casting: Parts from Pixels + Patrick Dunne, 3D Systems This presentation introduces a transformative approach


to producing high-density arrays of investment casting patterns using digital light processing (DLP) 3D printing. Entire casting trees — including parts, sprues, runners, risers, and vents — are printed in place as a single, monolithic structure. Arrays are rapidly configured and optimized in software with just a few clicks, reducing hours of manual labor to minutes.
