【摘要】 光固化3D打印是最早出现的3D打印技术,经过30多年的发展,先后发展出液态树脂固化或光固化(stereolithography,SLA)、数字光处理(digital light processing,DLP)、液晶显示(liquid crystal display,LCD)、连续无分层液体界面提取技术(layerless continuous liquid interface production,CLIP)、双光子3D打印(two-photon polymerization,TPP)、全息3D打印技术等多种打印技术。光固化3D打印技术具有精度高、成型速度快等特点,因此在许多领域都有良好的应用,且前景广阔。在众多领域中,齿科领域个性化特征明显,对打印材料精度要求高,是目前光固化3D打印最有应用潜力和高附加值的领域。本文综述了光固化3D打印技术的种类、原理和技术的优缺点,并简述了光固化3D打印在齿科领域的应用。更多还原

【Abstract】 The first 3D printing machine which was based on the photo-curing technology was invented in the1988.After more than 30 years of development,photo-curing 3D printing has the technology of SLA,DLP,LCD,CLIP,two-photon polymerization,holographic 3D printing technology and so on.Due to the character of high resolution,fast printing speed,photo-curing 3D printing technology has been widely applicated in several fields.Among these applications,the application of photo-curing 3D printing in the dental field is the most potential and highest value-added.The dental field has a distinctive and very individual character.At the same time,the dental field requires the printing sample with high resolution,which matches with the photo-curing 3D printing perfectly.In this article,the type,principle and the advantages and disadvantages of the photo-curing3 dprinting were introduced and its application in dental field was also described briefly.更多还原
