Book Description
Optically transparent and structurally sound, glass has played a significant role in the evolution of product and architectural design across scales and disciplines, and throughout the ages. Glass processing methods - such as blowing, pressing, and forming - have aimed at achieving increased glass performance and functionality. Nonetheless, techniques and technologies enabling controlled tunability of its optical and mechanical properties at high spatial manufacturing resolution have remained an end without a means. This thesis presents GLASS II - a high fidelity, large-scale, additive manufacturing technology for optically transparent glass combined with demonstrations of novelty through a construction of fully transparent glass structures at architectural scale. The enabling technology builds upon previous research conducted at the Mediated Matter Group and introduces a fundamental restructuring of the platform's architecture and process control informed by the material properties and behaviors of silicate glass. The new manufacturing technology provides a digitally integrated thermal control system across the entire glass forming processes, combined with a novel 4-axis motion control system; enabling a high fidelity manufacturing process capable of producing glass structures with tunable yet predictable mechanical and optical properties. The material fundamentally drives how the machine is used, and in return, the machine can change how the glass is formed and used. In order to evaluate the full capability of this new manufacturing technology, a series of three-meter tall glass column structures were designed, engineered, manufactured, and constructed. Harnessing its optical transparency in conjunction with the spatial tunability of the material deposition across the full length of the column, geometry of each column is topologically optimized under the material constrains of the viscoelastic filament such that the result provides highly efficient structural performance as free standing columns while each layer of the printed glass acts as a lens and transforms the incoming light into spatial interactions of kaleidoscopic caustics. This large-scale multifunctional 3D printed glass structure, embodying a new mode of transparency in architecture, was exhibited in Italy for the first time during the Milan Design Week in April 2017.

Book Description
"There are many scientific and engineering applications of glass including optics, communications, electronics, and hermetic seals, there has been minimal research towards the Additive Manufacturing (AM) of transparent glass parts. The special thermal and optical properties of glasses make them hard to be printed using conventional AM techniques. In this dissertation, two different AM techniques for glass AM were developed, Selective Laser Melting (SLM) and filament fed process. Semi-transparent parts were printed with SLM process. However, the filament fed process was found to be more robust and promising for printing optically transparent glass parts. Therefore, this dissertation is focused on filament fed process for different types of glass, including soda lime glass, fused quartz and borosilicate glass. For soda lime glass, the optical quality of the best printed part was found to be as good as furnace cast glass part using the same type of filaments. Optical defects and refractive index inhomogeneity can be linked to the molten region temperature. Furthermore, the mechanism of bubble formation in soda lime glass printing was also studied. Different regimes of bubble formation were found corresponding with different process parameters. Though the melting temperature of fused quartz is very high (~2300 °C), 3D fully transparent cubes with high index homogeneity were printed. For borosilicate glass, 3D fully transparent parts were printed, and the optical quality of best printed sample is as good as conventionally manufactured borosilicate glass"--Abstract, page iv.

Book Description
This book presents a comprehensive and holistic study of microstrucure evoution during solidification and additive manufacturin.g Bulk metallic glasses and their composites have attracted a lot of attention lately in the scientific community owing to their excellent mechanical properties (combination of hardness, strength, and high elastic strain limit). However, they still lack toughness and tensile ductility and exhibit catastrophic failure upon tension. This can be overcome by various means, of which in situ introduction of ductile crystalline precipitates/phases during solidification proved to be the best. Various studies have been carried out in the last two decades, which explain this phenomenon. However, there is a gap on how this can be achieved in modern additive manufacturing exploiting inherent nature of process. This book aims to bridge this gap. A comprehensive and holistic study is presented, documenting the step-by-step evolution of these materials since their inception till date, explaining the development of toughness in them by modeling and simulation of microstructure evolution during solidification and additive manufacturing.

Book Description
In this thesis, I explore relationships between form generation, material properties, and design constraints in search of a new framework for designing with unpredictable or unstable material systems using glass 3D printing as a case study. Molten glass forming has always been difficult to accurately predict or model, but also offers a high degree of geometric complexity or hierarchy through organic formations. Top-down design approaches to material tunability and control are enabled by new digital fabrication tools and technologies that offer some of most successful attempts to design at scales approaching that of nature [38] [20]. Bottom-up, material-driven systems design functionality, itself, around organically formed structures to challenge our perspective of designing for utility, and how to define that utility [18]. The glass 3D printer, developed by The Mediated Matter Group in collaboration with the MIT Glass Lab, has been an important case study long in the making. A novel type of glass forming quickly gave way to a dialogue with highly unstable material behaviors, structures too complex to model in real time and visually compelling, frozen in time with cooling temperatures. The process generates new types of glass structures and visual output, enabling new design typologies for the product and architectural scale. Here I present an array of over a hundred unique design experiments that offer insight into this brand new design space created by complex glass behavior under control of a digital machine and harnessing structural instability. Close study not only of the objects generated but also their behavior during fabrication is key to understanding how the glass responds to the motion of the machine. Analysis of the project workflow itself provides the foundation for a framework capable of handling an active and complex material system, identifying how and when machine control can be used directly, how and when organic material formation can take place, and how the two interface from design tool to fabrication tool to design product. Finally, I look ahead to the potential for new product and architectural functionalities enabled by this platform, and I establish concepts for using the highly complex forms with the mapped "design space" as a guide for what we understand to be possible. The goal is to form new knowledge about material-informed digital fabrication through the generation of new glass forms and designs.

Book Description
The thesis presents an Additive Manufacturing Enabling Technology for Optically Transparent Glass. The platform builds on existing manufacturing traditions and introduces new dimensions of novelty across scales by producing unique structures with numerous potential applications in product-, and architectural-design. The platform is comprised of scalable modular elements able to operate at the high temperatures required to process glass from a molten state to an annealed product. The process demonstrated enables the construction of 3D parts as described by Computer Aided Design (CAD) models. Processing parameters such as temperature, flow rate, layer height and feed rate, can be adjusted to tailor the printing process to the desired component; its shape and its properties. The research explores, defines and hard-codes geometric constraints and coiling patterns as well as the integration of various colors into the current controllable process, contributing to a new design and manufacturing space. Performed characterization of the printed material to determine its morphological, mechanical and optical properties, is presented and discussed. Printed parts demonstrated strong adhesion between layers and satisfying optical clarity. The molten glass 3D printer as well as the fabricated objects exhibited, demonstrate the production of parts which are highly repeatable, enable light transmission, and resemble the visual and mechanical performance of glass constructs that are conventionally obtained. Utilizing the optical nature of glass, complex caustic patterns were created by projecting light through the printed objects. The 3D printed glass objects and process described here, aim to contribute new capabilities to the ever-evolving history of a very challenging but limitless material - glass.
