Synthesized β-TCP powder was mixed with light-curing resin and polyethylene glycol and poured into a vat of the LCD 3D printer. The CAD data of the gyroid structure with interconnecting holes was prepared for 3D printing. The printed green bodies were sintered at various temperatures for 3 h to obtain sintered bodies. As the sintering temperature increased, the degree of sintering of β-TCP progressed, the size of the sintered body decreased, and the maximum compressive strength increased. It was found that the clustering of the SEM images of 3D printed β-TCP sintered at different temperatures can be made by transfer learning and hierarchical cluster analysis. Images of the sintered β-TCP surface can be classified by deep learning (transfer learning) and cluster analysis. The constructed model in this study successfully predicted the compressive strength of the 3D printed sintered bodies from their SEM images. The proposed deep learning method can be used for future surface property analyses of ceramic materials and sintering condition optimization.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"62 5","pages":"2203 - 2215"},"PeriodicalIF":2.6,"publicationDate":"2026-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149309855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rice husk ash (RHA), yeast, and graphite waste were used as pore-forming agents in the fabrication of samples with different loadings and nano-Cu concentrations. Total porosity increased with increasing pore-former loading (24–61.8%, 21–63.8%, and 24.5–49.5% for samples based on graphite waste, yeast, and RHA, respectively), which reduced the cross-sectional area for load bearing and consequently decreased mechanical strength. For the corresponding systems, the tensile strengths were 14.3–46.4 MPa, 5.4–37.3 MPa, and 19–48.3 MPa, while the flexural strengths were 30.4–123.4 MPa, 20.7–95.7 MPa, and 63.6–207.3 MPa. Through pore bridging and partial filling, nano-Cu inclusion significantly improved both properties and improved stress transfer within the matrix.

Clearly, the ANN model outperformed conventional regression techniques in terms of prediction accuracy and successfully represented the nonlinear correlations between mechanical performance and processing parameters.
