Selective Laser Sintering (SLS)
Fabrication and compressive behavior analysis of BCC, BFCC, and TPMS Gyroid Lattice Structures 3D printed with epoxy thermoset via selective laser sintering
This study introduces the use of epoxy-based thermoset powder in selective laser sintering (SLS) to fabricate BCC, BFCC, and TPMS Gyroid lattices with tunable thermomechanical properties. The research investigates the physical and geometric attributes of the 3D-printed parts before and after post-curing. It further assesses their compressive strength and energy absorption capabilities at both room temperature (RT) and an elevated temperature (ET) of 80◦C.
Fused Filament Fabrication (FFF)
Additive Manufacturing of Multi-Functional PEEK-Carbon Fiber-CNT composite Lattices for Tunable Temperature and Force Sensing
This study introduces a novel 3D printing filament combining PolyEtherEtherKetone (PEEK), Carbon Fiber (CF), and Carbon Nanotubes (CNT) to produce lattice structures with tunable thermo-piezoresistive properties. The enhanced filament demonstrates improved printability and selective sensing capabilities, offering significant advancements for applications in aerospace and biomedical fields.

Post-processing and composites
FEniCS modeling and experimental validation through optical image processing of the sintering process of compact powders
Modeling of the shape distortion and shrinkage during the sintering process of materials using FEniCS and python. This data is then validated by doing polymer sintering in a tube furnace and gathering data through image processing using python. This data will allow to understand the shrinkage phenomenon during sintering and the effect of different parameters.
Mylar Repair in Space Environments
The project is designed to rigorously test and analyze the performance of Mylar repair techniques under the harsh conditions of space. By examining the material's durability and the success of different repair approaches, the study will provide critical insights into how well these methods can withstand the extreme temperatures, radiation, and vacuum of outer space. This information will be invaluable for future missions, ensuring that spacecraft and equipment can be efficiently maintained and repaired while in orbit or on other celestial bodies.
