Carbon enhances its focus on textures for 3D printing using a novel software technique.

Over the past few years, my optimism about the potential of textures in additive manufacturing (AM) has grown significantly. I firmly believe that textures have the power to enhance function and perceived value, ultimately accelerating consumer adoption of 3D printed goods and making them more valuable. Not only could the best texture for an orthopedic implant be highly valuable to a single orthotist, but it could also potentially lead to a monopoly in that field. Additionally, by creating functional texture libraries, we could further expedite the adoption of additive manufacturing.

Recently, I came across some exciting research by Carbon that explores the role of textures in enhancing the appearance and functionality of 3D printed parts. Carbon acknowledges that current texturing processes, such as displacement and texture maps, can be cumbersome. However, they have identified the real challenge to be in correctly mapping textures to variable surfaces. In order to address this issue, they have developed a robust texture mapping algorithm based on the work of Boris Springborn.

Springborn’s work on discrete Riemann surfaces, particularly his paper on discrete conformal equivalence of polyhedral surfaces, presents a powerful method for mapping textures to meshes. This technology has the potential to consistently map textures onto any mesh surface. By introducing cone shapes to a mesh, distortion can be corrected and any mesh can be parametrically altered consistently. Additionally, problematic triangles can be addressed by flipping their edges while mapping normals through a data structure, thereby reconstructing the mesh with accurate triangles.

The significance of this discovery lies in the abundance of mesh geometry. Wrapping textures around a part can be challenging and may result in inconsistencies, especially when complex tactile responses are desired. For example, imagine a knife designed to guide the user’s grip for safety. In order for textures to be universally applicable, the wrapping issues must be resolved. It is essential for this process to be easily incorporated into CAD or added by any machine operator, ensuring consistent results every time. This consistency is particularly crucial in mass customization scenarios.

Springborn’s geometry could not only be utilized for universal mesh repair, but also for translating meshes into new data formats. This could breathe new life into the humble mesh and potentially enable all video game geometry to be 3D printable.

Carbon has now implemented this technology with their own unique touch, aiming to enhance triangulation quality in meshes for better and faster processing. While I hope that Carbon does not introduce any unnecessary intellectual property claims over this revolutionary approach (considering many have been working on it since 2008), I am glad to see that they are exploring avenues for optimization.

The future of textures in additive manufacturing is undeniably bright. With innovations like these, the field is poised for significant growth, and I am eagerly anticipating the possibilities it will uncover. Whether it be the creation of new tactile experiences or universal solutions for mesh repair, the potential is limitless.
