Mixed Material Optimization and Injection Project Berkeley, CA 2018

Designed and implemented a simulation to acquire an optimal combination of two materials.

Integrated machine learning into genetic algorithms to achieve the desired mixed properties (bulk modulus, shear modulus, and electrical conductivity) and lowered the cost function to 10-6.

Programmed a 3D printing simulation of the mixed material and calculated the wear rate of the printing nozzle.

Calculated the movement input to 3D printing robot arm dynamics (3 linkages) to print the desired pattern.

Laser Manufacturing Simulation: Finite Element Berkeley, CA 2018

Simulated a laser heated 3-D block model using finite difference and finite element with different number of nodes.

Implemented adaptive meshing to accurately track the temperature profile in the middle of the block.

Achieved an error as little as 10-8 compared to the analytical solution in a simulation of 10 seconds.

Automated Injection 3-D Pen Research St. Louis, MO 2017

Led design and programmed an Arduino and a platform sensor for a 3-D pen to inject only at specific locations while moving randomly.

Obtained the precise pen location with <0.2 second delay using infrared emitter attached at the tip of the extruder.

Gravity Powered Light Design St. Louis, MO 2016

Developed and tested an affordable light ($9) powered only by attaching a weight to it which took Lego gears as the powertrain. Designed and drew 4 concept drawings and analyzed each advantage and feasibility.

Modeled the CAD of the main cylinder, shaft, and the gears using SOLIDWORKS. 3-D printed the main cylinder and the casing of the device to reduce the cost of production.

Analyzed and computed the force needed, light duration, rope length, and the power output of the device based on the DC motor rotating speed.

Managed the bill of materials (BOM) and pricing strategy to keep the total cost below the limit (<$10).

Recently graduated from UC Berkeley with Master’s degree in Mechanical Engineering in May 2018. Proficient CAD skills, well educated in experiment design and testing, Finite Element Analysis (FEA), GD&T, and DFM. Dynamic leader with the ability to respond to changes in project goals and limitations. Utilize feedback-oriented discussion to organize the team to align with the objectives and possible improvements. Adept in modelling and simulating manufacturing process including deformation, heat transfer, CFD, 3D printing, and laser manufacturing.
