SketchChair is an innovative, free software tool that empowers individuals to create and construct their own custom furniture using digital fabrication techniques. While digital manufacturing offers vast potential for crafting one-of-a-kind items, there is a noticeable gap in user-friendly digital tools that enable everyone to design and produce their personalized, functional products. We believe that SketchChair addresses this gap by providing an accessible platform for individuals to design original chairs that reflect their unique tastes and preferences. Users can upload their creations to the SketchChair design library, contributing to a growing repository of open-source designs. This collection is available for anyone to download and modify, fostering a collaborative environment where chair designs can be continuously improved and reimagined. SketchChair thrives as an open-source initiative, made possible by the generosity of our supporters, and aims to inspire creativity in furniture design for all. By inviting users to share their designs, we hope to cultivate a vibrant community of designers and makers.
