3D printing technology could revolutionize the cost and sustainability of housing across the globe. Not to mention, the environmental impact of concrete use (spoiler: it’s not great) is of increasing concern. The key to shifting away from concrete may be reviving the traditional use of local soils—for a 3D printing process. Here to talk to us about his work helping to develop these new 3D printing techniques is Dr. Sarbajit Banerjee, Professor of Chemistry and Materials Science and Engineering at Texas A&M University.
