Baja SAE Racing Club CNC Machinist West Lafayette, IN 08/2021 – Current

• Worked with senior design member to create CAM on Fusion 360 for various parts

• Manufactured 8 rear wheel hubs with 2 operations for each and custom soft jaws within 4 weeks

• Milled Cable Throttle ends on a 5-axis HAAS VF4

• Turned Stock on a HAAS ST20 and ST20Y lathes and machined into 4 steering yokes on a HAAS VF2 in 6 different operations PROJECTS

3D Printer Optimization 08/2020 – Current

• Troubleshooted Ender 3 to find out why printed parts are printing inaccurately and inconsistently

• Added all metal hot end for higher temperature printing and improve nozzle extrusion rate for more versatility in printing

• Installed new mainboard with TMC2209 motor drivers to quiet stepper motors and allow for smoother operation of motors

• Replaced extruder for all metal extruder for more consistent extrusion of material

• Installed a BLTouch for automatic bed leveling for more consistent first layer printing increasing overall prototyping speed

• Increased default print temperature, added 5x5 mesh leveling, and enabled stealth chop in firmware to accommodate new parts

• Improved Cura print profiles to increase print reliability, accuracy, and print speed Training Butterfly Knife 01/2023 – Current

• Designed shape similar to popular designs currently popular in industry to make sure product is familiar when in use

• Corrected weight balancing with CAD analysis tools to center weight near front of handle for ideal flipping

• Developed an opening and closing mechanism to make butterfly knife easily storable and comfortable when in use

• 3D printed 2 iterations of butterfly knife to test for size and hand feel

• Updated final iteration of butterfly knife with manufacturing processes in mind with parts from McMaster-Carr

• Customized handle and blade based on consumer feedback for increased appeal Modeling 1 CAD Model a Week 12/2022 – Current

• Create 1 CAD Model a week in Solidworks using different techniques to familiarize with user interface and increase modeling speed

• Practice rapid designing and prototyping with Solidworks 3D by printing completed models

• Upload weekly pictures of finished models to Instagram to track progress and receive feedback Natural Catalyst Enzyme Analysis 03/2022 – 04/2022

• Created an algorithm on MATLAB to analyze enzyme data through regression analysis

• Worked in a team of 3 to code 5 functions to generate and model regressions based on enzyme data

• Improved efficiency and accuracy of regressions after initial tests to maximize accuracy of functions

• Communicated findings through a written report highlighting all stages of development for project SKILLS & COURSEWORK
