PROFILE
Alan Bjorklund
Alan contributed to the Ultimaker/Cura repository by developing and refining 3D printer configuration profiles, focusing on material support, hardware compatibility, and user experience. He implemented new material profiles and optimized print settings for platforms like Sketch, Replicator+, and Method, using Python and JSON for configuration management and G-code generation. Alan addressed workflow stability by tuning machine timing parameters and improving support structures, which reduced print failures and cycle times. He also enhanced the Cura UI by hiding sensitive acceleration parameters, preventing misconfiguration. His work demonstrated depth in 3D printing slicer logic, low-level parameter tuning, and cross-team software integration.

Apr 1, 2025April 2025: Delivered a focused UI/UX enhancement in Ultimaker Cura to hide gantry acceleration parameters and related values from the speed adjustment workflow, preventing misconfiguration when increasing print speed. This change reduces user confusion, protects critical configuration mappings, and supports the 5.10.1 release scope. Commit be052ae74d634fa0deb043659b08856a80be1cd0 was the implementation. Impact includes safer defaults, clearer UI, and decreased risk of incorrect speed settings. Technologies/skills demonstrated: UI/UX design, front-end development, code review, release engineering, and cross-team collaboration.
