The author reflects on their journey with 3D printing, highlighting the challenges faced in the design process compared to the actual printing. They note that while 3D printing technology itself is advancing rapidly, the design aspect remains cumbersome. Creating even simple parts requires extensive iterations and can be confusing due to version control issues. Traditional CAD software, like Fusion 360, has limitations such as poor version control, which complicates tracking changes between revisions. The author emphasizes the need for more intuitive versioning that aligns with software development practices. Collaboration in 3D design is another pain point. The author recounts their experience of remixing designs within the 3D printing community, where sharing improvements is cumbersome. Unlike software development, where contributors can submit changes for easy integration, CAD collaboration often requires all parties to use the same software. This hinders open-source contributions and makes the process feel less inclusive. The author also discusses the inefficiency of creating customizable parts, which often requires manual adjustments and uploads, lacking automation for scalability. To address these shortcomings, the author developed MakerRepo, a platform aimed at streamlining the design and collaboration process for 3D printing. They envision a future where manufacturing operates like software development, allowing users to create and modify designs with ease. By treating manufacturing as code, they aim to eliminate the barriers that currently stifle creativity and efficiency in design, paving the way for more tailored, user-driven production.
