摘要
3D打印技术以其“自下而上”进行材料累加的制造理念,为复杂结构件制造提供了新思路新方案,为航空、航天、汽车、医疗、建筑、艺术等领域开辟了更为广阔的应用场景。将3D打印材料分为金属材料、有机高分子材料、无机非金属材料三大类,通称为先进材料,并分别梳理和阐述各先进材料应用于国内外3D打印技术的最新研究成果。研究发现:随着工程化应用的深入,3D打印金属材料种类正在逐渐丰富,并通过合金化、增强基强化等手段提升性能;在有机高分子材料中,基于合成原理,实施改性和材料复合化,可有效改善线材性能,其中韧性和抗弯强度是重要研究指标;大多数无机非金属材料的研究围绕工艺适应性开展,部分材料已开始进入性能改善阶段。
3D printing provides new schemes for complex structural parts manufacturing through the"bottom-up"material accumulation method,and opens up application scenarios in aviation,aerospace,automobile,medical,architecture,art and other fields.3D printing materials are divided into metal materials,organic polymer materials and inorganic non-metallic materials,and the latest research results of advanced 3D printing technology at home and abroad under each material type are described respectively.Research findings:With the deepening of engineering applications,the raw materials of the new 3D printing process are mostly in the stage of process exploration,and the raw materials of the mature 3D printing process are gradually rich in types and significantly improved in performance.
