About Carbon Forming

Carbon Forming is a collaborative R&D mission that aims to embed CO2 removed from the air in 3D-printed objects through a distributed, solar powered, modular platform. The mission kicked off in early 2022 through the initiative of a small team of scientists, designers, engineers and artists located all over North America. By expanding this collaboration to include the insights, ideas and support of a much larger global community, the mission team aims to rapidly evolve the concept into a real world, functional prototype.

  • On this forum we aim to collectively solve mission-related challenges, and surface new ideas and advancements through open exchange.

  • All are welcome to contribute, share and learn. The more diverse our collective expertise, knowledge and perspective, the faster Carbon Forming will evolve and improve.
