Responsibilities include:

• Developed new features for PreForm software and supported the development of upcoming Formlabs printers
• Designed and implemented efficient auto-fill algorithms for SLA (Stereolithography), a long-requested feature now used by 100k+ of PreForm users worldwide, achieving plate fills in about 20 seconds even for complex geometries
• Researched, documented, and evaluated algorithms for the fill the build feature, collaborating with supervisors and colleagues to finalize the approach
• Resolved a long-standing issue with Qt not bundling correctly for PreForm’s Python binding on macOS
• Refactored and improved X/Y scaling compensation settings for better user experience; reorganized printer task codebase to improve maintainability

Responsibilities include:

• Designed path planning graphics algorithms for new flagship multi-tool head 3D printer H2D and H2S, mainly worked on Bambu Suite
• Designed and implemented Gcode generation for new tool head, including laser, vinyl cut, and draw pen functionalities
• Independently developed an algorithm for dynamically adjusting tool path planning in vinyl cutting, ensuring precision with passive knives
• Investigated and drafted technical solution for backend pipeline of draw pen and laser engrave on curved surfaces
• Contributed more than 1,000 lines of C++; improved vinyl cut and draw pen precision from 10mm to 2mm
• Wrote 10+ technical documentation about 3D printer tool head path planning algorithm design and experiment records, with a total of 20k+ words, helped coworkers to understand backend algorithms
