摘要
3D打印技术已广泛应用于诸多行业,近几年发展十分迅速,聚乳酸作为一种优良的可生物兼容可降解材料,因其成型温度和成型工艺良好,成为3D打印技术最常用的原材料之一。该文围绕3D打印用聚乳酸(PLA)材料的优缺点进行系统地对比分析,并通过单轴压缩试验证实与阐述PLA材料不适用于模拟煤岩材料,同时列举PLA材料在3D打印中的应用现状。由于PLA存在性价比高、安全环保、无毒无害等诸多优点,因此,研究PLA的性能,具有重要的应用价值。
3D printing technology has been widely used in many industries,and it has developed rapidly in recent years.Polylactic acid(PLA),as an excellent biocompatible and degradable material,has become one of the most commonly used raw materials for 3D printing technology because of its good molding temperature and molding process.This paper makes a systematic comparative analysis of the advantages and disadvantages of polylactic acid(PLA)materials for 3D printing,confirms and expounds that PLA materials are not suitable for simulated coal and rock materials through uniaxial compression tests,and enumerates the application status of PLA materials in 3D printing.Since PLA has many advantages,such as high performance-to-price ratio,safety and environment-friendliness,non-toxicity and harmlessness,it is of important application value to study the performance of PLA.
