The advancement of bio-based materials combined with additive manufacturing (AM) technology has created new opportunities for sustainable innovation and local economic empowerment. This study investigates the potential of polylactic acid (PLA) as a biodegradable and sustainable polymer derived from natural resources such as corn starch and sugarcane. Although PLA offers promising alternatives to petroleum-based plastics, their integration into community-based production through additive manufacturing remains underutilized. Local handicraft in micro, small, and medium enterprise (MSME) often lack the knowledge, tools, and technical capacity to transition from traditional manufacturing to digital fabrication methods. Consequently, opportunities to improve product quality, environmental sustainability, and market competitiveness remain untapped. In this study, PLA was applied for handicraft-based product development using 3D printing. The study was conducted as part of a community development aimed at strengthening MSME operating in the creative and handicraft sector of Padang City, Indonesia. The program introduced participants to the principles of sustainable design and digital fabrication, through a structured approach. This involved capacity building workshop, design mentoring, and hands-on prototyping. Local handicraftsmen were guided in adapting crafting techniques to incorporate 3D printing using PLA filaments, enabling the creation of eco-friendly and customizable products. This study showcases how merging craftsmanship with modern digital technology can empower local community. The study shows that integrating additive manufacturing (AM) into local handicraft production improves design flexibility (14%), reduces material waste (7%), enhances customization (12%), and strengthens technical skills (7%). These outcomes demonstrate increased efficiency, sustainability, and competitiveness, supporting innovation and resilience in localized handicraft enterprises.
