Ceramic Binder Jet 3D Printing for Concentrating Solar Power Technology

In this poster, ceramic Binder Jet 3D printing (BJ3DP) for concentrating solar power (CSP) technology is investigated. BJ3DP functions by depositing layers powder and binder to form a green part. There is no need for support materials because the excess powder deposited supports the green part. BJ3DP is a great alternative to machined parts, especially for ceramics due to their hardness. Currently, next generation CSPs are targeting higher operating temperatures to increase their efficiency. This paper investigates the effect of printer compaction on the final part to increase green density. SiC 10-50um powder is used with phenolic binder for printing. Currently, we face challenges with deformation of the printed parts. Due to compaction, increases in density of above 17% were observed. It is proposed that materials with a higher density will allow next generation CSP plants to reach and maintain higher operating temperatures.
