Overview

• The team combined binder jet additive manufacturing with targeted post‑processing to produce leak‑tight ceramic assemblies.
• A printed part was infiltrated with a silicon‑carbide pre‑ceramic polymer and heat‑treated to form amorphous silicon carbide as a demonstration of the approach.
• Researchers evaluated multiple design configurations and refined bonding and sealing steps to achieve verified gas‑tight integrity.
• The work highlights cost advantages of binder jetting and points to applications in high‑throughput chemical reactors, aerospace, and clean‑energy equipment.
• Findings were published in Ceramics International and recognized with SME’s 2025 Dick Aubin Distinguished Paper Award, with support from ARPA‑E, the Solar Energy Technologies Office, and ORNL’s Manufacturing Demonstration Facility.
