Farewell STLs, Hail to the 3MF Revolution with Duann Scott

The Prosthetics and Orthotics Podcast

In this conversation, Joris Peels and Brent Wright interview Duann Scott, the head of the 3MF Consortium, about 3D printing, software, and the future of file formats. They discuss the benefits of the 3MF file format, its security features, and the implications for the 3D printing industry. The conversation also covers lattice structures, implicit files, and the importance of data communication in 3D printing. The conversation delves into the use of implicit modeling and lattice structures in 3D printing, the benefits of bypassing the meshing process, and the potential for streaming slicing. It also explores the concept of systems-level approach in design, the role of computational workflows, and the importance of seeking expert advice. The conversation concludes with a discussion on the speed of iteration and the liberating nature of additive manufacturing.

Takeaways

• The 3MF file format offers significant advantages over the traditional STL format, including smaller file sizes, color and texture preservation, and the ability to carry metadata and manufacturing information.
• The 3MF Consortium is an open-source initiative that aims to standardize 3D printing file formats and ensure interoperability between different software and hardware systems.
• Security features in the 3MF file format allow for restrictions on file access, printing permissions, and machine-specific usage, providing greater control and protection for 3D printing files.
• Lattice structures and implicit files offer efficient ways to describe complex geometries in 3D printing, enabling smaller file sizes and more elegant data communication.
• The conversation highlights the need for the 3D printing industry to mature in terms of data communication and file format standards, emphasizing the importance of proper data flow and scalability. Implicit modeling and ladder structures offer an efficient and powerful way to create complex geometry in 3D printing.
• Bypassing the meshing process and streaming slices can improve the speed and efficiency of the 3D printing process.
• A systems-level approach to design, along with computational workflows, can lead to more robust and flexible solutions.
• Seeking expert advice and surrounding oneself with knowledgeable individuals is crucial when navigating the complexities of additive manufacturing.
• The speed of iteration and the liberating nature of additive manufacturing offer new possibilities for design and production.
