Item Digital craft : handmade craft meets digital design(2011-05) Miller, Rebecca Leah; Glavan, James; Mickey, Susan E.; Sawyer, MargoDigital Craft is a project that explores the interface between three-dimensional (3-D) computer technology and costume technology. I combine seasoned millinery techniques with modern methods of object construction and design to diversify the costume artisan’s toolbox and encourage practical and useful ways of moving between the virtual and physical world. Through a series of theoretical projects the dichotomy of modern artistic process is explored. The task of this thesis project is to explore the impact of 3-D imaging software on design and construction methods by applying them to the sculptural process of hat making. I collaborate with designers and technicians to develop methods of hat making for performance culminating in an exhibition presented at the University Co-op Cohen New Works Festival, April 2011. This research is applied to cultivate new methods of hat making, by exploring new media and expanding creative possibilities. Craft objects are created directly through the hand of the maker; it is thorough technique that the hand informs the craft object (Risatti, 108). Furthermore, the traditional notion of tools and craft objects is that they are conditioned, controlled and limited by the hands. In order to update and improve methods of object construction, this project will expand the traditional concept of craft, combining hands-on methods with machining. I hope to improve efficiency and decrease the cost of realizing authentic and original hat designs by exploring alternative digital spaces that can be used to communicate, develop and actualize ideas.Item Effect of Inter-Layer Cooling Time on Distortion and Mechanical Properties in Metal Additive Manufacturing(University of Texas at Austin, 2018) Bandari, Y.K.; Lee, Y.S.; Nandwana, P.; Richardson, B.S.; Adediran, A.I.; Love, L.J.Laser Metal Deposition with wire (LMD-w) is one of the novel Direct Energy Deposition (DED) processes that is gaining the attention of various industries, especially aerospace, due to the potential cost and lead time reductions for complex parts. However, subjects of development include optimization of process parameters (for example laser power, wire feed speed, robotic travel speed, inter-layer cooling time etc.) for large scale adaption of this process. These parameters influence residual stress which potentially results in distortion and subsequent mechanical properties. Inter-layer cooling time is one of the main influences on production volume and is typically used to help control the cooling conditions to mitigate part distortion. Therefore, this paper is aimed at investigating different inter-layer cooling times on distortion and resulting mechanical properties of the parts produced by LMD-w. Distortion of deposited Ti-6Al-4V walls was measured automatically using a laser scanner, which was attached to the robotic arm itself. Finally, suitable recommendations are discussed to optimize the inter-layer cooling time to produce parts with desired mechanical properties.Item Playing with masks : an exploration of craft and performance(2014-05) Kurz, Danielle Haskell; Glavan, JamesCollaboration between the playwright, director, designer and technicians is the backbone of theater. Costume designers, after discussion with the director and the other designers, rely on costume technicians to realize their ideas. The technician’s hands then realize the artistic vision. But what would the technicians try if there were no constraints? I am a technician, a craftsperson who is inspired not just by the play, but also by process, by methods. With every new technique I learn, I imagine the new ways it could be put to use, and the objects I would create if time and resources were not a factor. Imagined objects are seldom created. Once made, these objects exist without a performance, without a purpose. A costume not worn is an unfulfilled destiny. But maybe the pieces I want to make can be given a narrative after the act of construction, or during construction. I’m interested in exploring my ability to be a generative artist. How can my inspiration feed back into the theater community? Can a costume technician’s experimentation have a place in creating new theater? My thesis has two components, exploring my two interests. Those two interests are the creation of objects and the creation of a story. The first component, object creation, was an exploratory study of mask and headdress making techniques. I experimented with new techniques, such as 3-D printing, testing the limitations of new technology. The second component, story creation, was a collaborative process. My collaborator, Brian Oglesby, and I worked concurrently. Brian is a playwright, and as he wrote the play, I made the objects. Our processes mirrored each other. The narrative of the play incorporated the masks and headpieces I made. This project created a theater piece based on the experimentation of a costume technician, and presents a new way for future technicians to think about their work and to have their stories told.Item Rheology and Applications of Particulate Composites in Additive Manufacturing(University of Texas at Austin, 2019) Xia, Bin; Krueger, Paul S.To provide different functionalities such as electrical conductivity or magnetic permeability, particulate composites have been utilized widely in additive manufacturing. These types of materials are usually formulated with different functional particles and shear thinning non-Newtonian fluids such as polymer melts and silicone. The materials are viscous non-Newtonian suspensions during formulation and printing, and their rheology is a key factor for the processing. This paper will concentrate on suspensions with micron-sized particles, and discuss the rheology and overall flow behavior in capillaries scaled appropriately for additive manufacturing applications (around 1 mm ID). Micron size glass beads and shear thinning silicone are used to demonstrate the impact of particle volume fraction on the shear thinning behavior. The impact of particle and capillary size on viscosity and jamming conditions will be discussed. Previous models based on Newtonian fluids and in free flowing conditions will also be reviewed and compared.
