PROFILE
Hao.jiang
Worked on BambuStudio, delivering features that advanced 3D printing workflows, including model orientation optimization for cooling efficiency and a robust multicolor filament mixing and slicing system. Developed orientation algorithms in C++ to align models with cooling fans, improving print reliability and reducing failures on complex geometries. Enhanced the import pipeline by introducing a blacklist to prevent unnecessary Z-axis rotations, streamlining model preparation. Built end-to-end support for dual and tri-color filament mixing, including GCode generation and UI controls for color management. Focused on software engineering best practices, integrating Jira for traceability and maintaining code quality through clear commit hygiene and documentation.

Jul 1, 2025July 2025 monthly summary for bambulab/BambuStudio: Delivered a feature to optimize 3D printing model orientation based on cooling fan direction, introducing a function to orient models and a load-after-orientation workflow to improve print quality and loading efficiency. The orientation logic is now robust and adaptable to different fan configurations, reducing orientation-related failures and enabling more consistent print results. No major bugs fixed this month. Overall business value: faster, more reliable print preparation and improved hardware-configuration support. Key technologies and skills demonstrated: orientation algorithms, integration with the loading pipeline, Jira integration (STUDIO-13267) and cherry-pick workflow.

May 1, 2025May 2025: Delivered the Model Orientation Cooling Optimization feature for BambuStudio to improve cooling efficiency and print reliability on prints with large overhangs. The change orients the model's largest overhang toward the printer's cooling fan, reducing cooling-related quality issues in challenging geometries. Work linked to STUDIO-11976 with commit ddd81ce0d621e83809b250c8ae422786f679ec46; Change-Id: Id2cbb7d58da079d3b10aa61c216c71b5a56a6233 (cherry-picked from an earlier commit). No major bugs fixed this month; focus remained on delivering high-impact functionality and ensuring traceability. Expected impact includes higher quality, more consistent results on complex prints, and improved predictability in outcomes. Technologies/skills demonstrated include 3D printing orientation optimization, Git-based traceability, Jira integration, and cherry-picking for parity across branches.
