The Effect Of Incorporating End-User Customization Into Additive Manufacturing Designs, Jonathan D. Ashley
The Effect Of Incorporating End-User Customization Into Additive Manufacturing Designs, Jonathan D. Ashley
Graduate Theses and Dissertations
In the realm of additive manufacturing there is an increasing trend among makers to create designs that allow for end-users to alter them prior to printing an artifact. Online design repositories have tools that facilitate the creation of such artifacts. There are currently no rules for how to create a good customizable design or a way to measure the degree of customization within a design. This work defines three types of customizations found in additive manufacturing and presents three metrics to measure the degree of customization within designs based on the three types of customization. The goal of this work …
Microheater Array Powder Sintering (Maps) For Printing Flexible Electronics, Nicholas Holt
Microheater Array Powder Sintering (Maps) For Printing Flexible Electronics, Nicholas Holt
Graduate Theses and Dissertations
Microheater array powder sintering (MAPS) is a novel additive manufacturing process that uses an array of microheaters to selectively sinter powder particles. MAPS shows great promise as a new method of printing flexible electronics by enabling digital curing of conductive inks on a variety of substrates. MAPS operation relies on establishing a precision air gap of a few microns between an array of microheaters, which can reach temperatures of 600°C, and a layer of conductive ink which can be deposited onto a flexible substrate. This system presents challenges, being: the fabrication of a microheater that can reach suitable temperatures in …
Phase Transitions In Monochalcogenide Monolayers, Mehrshad Mehboudi
Phase Transitions In Monochalcogenide Monolayers, Mehrshad Mehboudi
Graduate Theses and Dissertations
Since discovery of graphene in 2004 as a truly one-atom-thick material with extraordinary mechanical and electronic properties, researchers successfully predicted and synthesized many other two-dimensional materials such as transition metal dichalcogenides (TMDCs) and monochalcogenide monolayers (MMs). Graphene has a non-degenerate structural ground state that is key to its stability at room temperature. However, group IV monochalcogenides such as monolayers of SnSe, and GeSe have a fourfold degenerate ground state. This degeneracy in ground state can lead to structural instability, disorder, and phase transition in finite temperature. The energy that is required to overcome from one degenerate ground state to another …
