According to the Department of Energy’s Oak Ridge National Laboratory ORNL’s Brian Post, the project’s advanced manufacturing engineer, Diana Hun, lead buildings researcher on the project. We didn’t know if 3D-printed molds could be made to work for the precast industry. But we thought it was worthwhile to examine the potential.
With the Domino project, the challenge was to find the right solution for a job that required durable molds that could be used numerous times. We proved that each 3D printed mold could cast at least 200 concrete parts, which was key to meeting the project’s schedule.
Each mold takes between 8 to 11 hours to print and 8 hours to the machine to the desired surface finish”.
