The purpose of this research is to examine the effects of recycling PLA filament for 3D printing on its material properties. After examining these effects, PLA and carbon fiber additives were mixed with recycled PLA pellets in different ratios to attempt to regain material properties lost in the recycling process. To complete these findings, an experiment was design and executed.
The research found that tensile strength during multiple iterations of recycling remained mostly unaffected, however, the strain degraded exponentially. In the PLA additive study, high ratios of PLA additive were able to increase the strength and strain properties of the …

The goal of this project is to study the performance of a 3D printed mechanical part subjected to topology optimization. A part that is somewhat complex in its load bearing and geometry will be selected. That part will then be designed, finite element analysis will be performed on it to optimize its topology, and then it will be 3D printed and tested. The goal of topology optimization is to either save material cost and/or part weight due to the ability of 3D printing to manufacture parts with complex and obscure geometry.

During transport sensitive payloads can become subject to a multitude of vibration or shock environments that can lead to damage. Using only additive manufacturing we seek to design an isolation system that can provide enough vibration and shock damping to properly protect the payload. Using modern FEA software we were able to quickly analyze a variety of solutions and determine the best one. Based on the results we have achieved through analysis, as well as pushing the manufacturing capabilities of 3D printers, we believe it is plausible to use additive manufacturing to create a fully capable vibration isolation system.
