Developing A Measurement System To Assess Line Profile Retention In 3d Printing, Heng Li

Theses

Manufacturing three-dimensional (3D) objects with methods adapted from conventional digital printing have propelled the development of additive manufacturing. In this process, the printing devices directly deposit or fuse materials to form 3D solid objects in a layer-by-layer fashion, thereby creating the additive approach of fabrication.

As additive manufacturing (AM) has been increasingly adopted for rapid prototyping and part manufacturing, the need to determine the part quality which results from the processes becomes crucial (Monzón, Ortega, Martínez, & Ortega, 2015). There is a lack of quantifiable measurement systems to define a printer’s ability to resolve systematic and geometric features and dimensionalities …

Clearance Analysis Of 3d Printed Assemblies Using Fused Filament Extrusion, Kshitij Luthria

Theses

3D Printing technologies have been around for the better part of 30 years now, and researchers today have a reasonably good understanding of how the different processes work. A focus for the next era of 3D printing will likely be to gain a deeper understanding of how these processes can be used in unique applications. One such unique application that can potentially change the way conventional manufacturing works involves 3D printing of assemblies. By printing assemblies ‘in-situ’, multiple assembly steps can be by-passed, thus increasing efficiency and decreasing costs. This research specifically seeks to develop an understanding of how clearances …
