In this category we discuss various aspects related to the intersection of carbon removal and 3D printing, including: 1. Using 3D printing to improve OpenAir R&D projects, 2. Developing novel 3D printing filaments and/or resins that incorporate carbon-based materials, such as calcium carbonate (CaCO3), and 3. Building relationships with 3D printing suppliers and innovators to advance and deepen integration of 3D printing and CDR communities, worldwide.
