Assessed stainless steel densification and turnover rate under varying print parameters and processes
Analyzed fracture surfaces to identify microstructure evolution and pore prevalence
Investigated Metal Matrix composites through additive manufacturing and their applications in various industries
Metal Matrix Composites Research
MMCs are a class of materials that consist of one or more reinforcements to a base metallic matrix which
Allow a combination of unique metal characteristics such as ductility, toughness, and conductivity with wear resistance, stiffness, and rigidness of ceramic materials.
The material characteristics are determined by quality and interaction of reinforcement materials
Mass and Dimension Measurement
Use of an analytical balance and calipers to identify the dry sample density from the collected mass and volume information.

Vacuum Setting
Sintered samples are submerged in distilled water to displace air pockets and measure wet and dry-wet mass for the Archimedes principle.
This allows us to determine printed sample density and compare it with the theoretical value so that we can identify the offset percentage.
Light Filter Microscopy
Utilized to identify pores and defects on the sample surface after grinding and polishing. This depicts the effectiveness of the parameters the sample was printed at.
Grinding and Polishing
Use of Diamond, Alumina, and Colloidal silica suspension to polish sample and prepare for microscopy after grinding with high grit sandpaper.
