Warpage And Shape Distortion In Laser Metal Sintering, Xuan Wang

Industrial and Manufacturing Engineering

Selective Laser Sintering (SLS) is the primary method to fabricate metal and ceramic components in additive manufacturing. Due to the anisotropy of powder material, the sintering rate difference will inevitably causes shape change, distortion , and other defects of sintered parts. In this paper, a continuum model was developed to simulate the SLS process. The developed model has been successful to predict sintering kinetics. The impact of processing parameters, such as laser power, scanning speed, hatching distance, and particle size has been studied . The proposed method provides an innovative tool to optimize SLS process parameters.

Dissertations (1934 -)

The need for designing industrial machines with higher energy efficiency, reliability, flexibility, and accuracy has increased to satisfy market demand for higher productivity at reduced costs in a sustainable manner. As machines become more complex, model-based design is essential to overcome the challenges in mechatronic system design. However, a well-designed mechanical system with a well-designed and tuned control system are not sufficient for machines to operate at high-performance conditions; this also heavily depends on trajectory planning and the appropriate selection of the motors controlling the axes of the machine. In this work, a model-based design approach to properly select motors …

The Design For Manufacturing And Assembly Analysis And Redesign Of An Aircraft Refueling Door Hinge Utilizing Additive Manufacturing, Kurt A. Schwarz

Doctoral Dissertations and Master's Theses

In this thesis, an aircraft door hinge assembly provided by Gulfstream Aerospace was analyzed following an established process called DFMA. The hinge was then redesigned to be additively manufactured, which is uncommon currently in industry for load bearing components. It was shown that the Design for Manufacturing (DFM) guidelines were inadequate when applied to the new technology of additive manufacturing (AM). This was primarily due to AM's unique and unprecedented manufacturing capabilities.

A conservative redesign approach was followed due to a limitation in current AM material properties and time available for analysis. Despite this, a significant improvement in weight reduction …
