Mold design, fabrication and tensile testing of EMBed-812, a tissue embedding epoxy resin
Serial sectioning is a process whereby fixed tissue is embedded in a polymer to preserve structure and is then sliced into very thin sections as small as 25nm. Currently, there is a lack of understanding of this embedding material, preventing accurate and clean slicing at this level of precision. …

Breaking the Mold: Using Automated Design to Accelerate Composites Manufacturing
… component of lead time is the engineering design and toolpath generation for the molds used to manufacture the composite parts. This research seeks to automate mold design and toolpath generation, allowing CR to eliminate the labor bottleneck and establish short lead times as a competitive …

Design and manufacture of plastic markers for Agile Atoms DNA Set
My thesis focused on the design and manufacturing of plastic parts for the Agile Atoms DNA Set that is distributed by the MIT Edgerton Center. The design of the parts had to be easy to manufacture in-house, be easily differentiated, and be able to endure multiple use cycles. Many design aspects …

Prototyping of Injection EVA Foam Footwear Midsoles
… and non-uniform nature of how they expand after molding. Dealing with this expansion requires certain steps in the IP process and this study isolated three key aspects: expansion ratio (ER) grading, mold design, and part-making. The PCC then developed mold tools and three sets of midsoles to …

Electroforming of personalized miniature metal parts using additively manufactured molds
… on the development of additively manufactured molds to facilitate the electroforming of personalized metal parts. The methodology encompasses standardized mold design, experimental procedures for mold development and electroforming, and a simulation model for visualizing and predicting the …

Designing & Manufacturing Powder Skis
… of skis and how they affect skiing. From there I designed the shape and looked into the layering and material composition determining where to acquire all the materials. I began with the wooden core using a CNC machine to perfect it. Then cut out all the necessary layers including fiberglass and …

Computer Aided Design of Side Actions for Injection Molding of Complex Parts
Often complex molded parts include undercuts, patches on the part boundaries that are not accessible along the main mold opening directions. Undercuts are molded by incorporating side actions in the molds. Side actions are mold pieces that are removed from the part using translation directions …

Assessing an Orientation Model and Stress Tensor for Semi-Flexible Glass Fibers in Polypropylene Using a Sliding Plate Rheometer: for the Use of Simulating Processes
… generated during processing, such as injection molding. In an effort to optimize industrial processing, optimize mold design, and maximize desired properties of the final part, it is highly desirable to predict long fiber orientation as a function of processing conditions. The purpose of this …

Modeling of Microstructures and Stiffness of Injection Molded Long Glass Fiber Reinforced Thermoplastics
… resulted in the growth of the use of injection molded discontinuous fiber-reinforced thermoplastics. During the intensive injection molding process, severe fiber breakage arises in the plasticating stage leading to a broad fiber length distribution. Fiber orientation distribution (FOD) is …
