Design & Manufacturing
Project Overview
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.
