Mechanical Design
Screen Holder Redesign (OnShape CAD)
Inherited a legacy touchscreen mount with clearance and CAD dependency issues that blocked wire routing, I updated the mechanical constraints, built an independent parametric CAD model, and iterated through nine design revisions to improve wire-routing, manufacturability, and assembly. The final design featured a detachable components with heat-set inserts for easier maintenance, passed all fit tests, and was integrated into functional prototypes—unblocking the software team and enabling direct print kickoffs from the hardware.
Conductive Homing Bracket (OnShape CAD)
To improve automated positional calibration, I designed a rigid, hardware-compatible mount for the sensing component that fit within the printer’s build volume. Using OnShape CAD, I developed and tested eight iterations to optimize positional repeatability, manufacturability, and clearance, verifying fit and electrical integration in collaboration with the EE team. The final design integrated seamlessly with existing hardware features, was deployed into the printer assembly, and unblocked downstream development—accelerating prototype validation for a critical system capability.
Printer Assembly
To expand Studio 3e8’s internal R&D printing capacity, I assembled two next-gen printer frames and critical subsystems end-to-end. This included mechanical and electrical integration—precision soldering, wire crimping, component mounting, and installing motors, switches, and sensors per schematics. I validated performance by CAD-modeling and printing a custom test part used in 20+ successful prints, and iteratively troubleshot for electrical continuity and mechanical fit before full deployment. Additionally, post assembly, provided DFM/DFA suggestions to manufacturing team.
Software Development
Print Tracker API SlackBot
To streamline remote monitoring of active 3D prints, I built a lightweight alert system that pushed real-time status updates to Slack. Using TypeScript and SQL, I scripted database polling to detect state changes and integrated with the Slack API to post updates like print start and completion. The system enabled frictionless, multi-device monitoring, reduced manual check-ins, and—after refining the logic to trigger at critical instances —cut message noise by 80% while improving response efficiency.
Material Usage Tracking
To give the team more accurate material usage estimates per print and per layer, I augmented the company’s internal slicing software with new volume calculation capabilities. Working with the Software and UI teams, I injected new Python logic into the slicing data pipeline to compute per-layer and cumulative material usage, surfacing results in the front-end. Following Git workflow best practices for modularity and compatibility, I deployed the update to the company’s GitHub, where it was continually used in multiple live prints.
Print Capabilities
Fine Feature Analysis
Independently designed, printed, and tested a multi-feature benchmark part in OnShape to evaluate the fine-feature performance of studio 3e8’s flagship printer fleet. Incorporating tolerance tests, geometric resolution, and surface finish features, I ran 20+ trials across machines to assess feature size limitations and post-processing impacts. The project delivered a comprehensive print quality matrix and a standardized SOP, informing internal QA benchmarks and onboarding materials for future users.
