Biomass materials, an important source of chemical feedstocks, could replace fossil fuels as a resource in the future. The chemical feedstocks from biomass materials are used in many medical and pharmaceutical products and in fuels, chemicals, and functional materials. Biomass materials are expected to be used in biomedical engineering fields, especially due to their low biotoxicity. By the way, most of the demand for bio-application fields is an application targeted for customized production, so a high formability is required for production. Research on three-dimensional (3D) printing technology capable of satisfying these requirements has been ongoing. Manufacturing additives need to be investigated to use biomass materials as a resin or bioink safely for 3D printing, which is a technique widely used in biomedical engineering fields. In this study, a projection microstereolithography (PμSL) system, a 3D printing technique, was made that uses a biomass-based resin. Biomass materials are designed to be photocurable for use in the PμSL process. Various PμSL process parameters were investigated using the biomass-based resin to determine the optimum fabrication conditions for 3D structures. This study demonstrated that a biomass-based resin can be used in the PμSL process. We provide a method for its application in various biomedical engineering fields.
生物质材料作为化学原料的重要来源，未来有望取代化石燃料成为一种资源。来自生物质材料的化学原料被用于许多医疗和制药产品以及燃料、化学品和功能材料中。生物质材料因其低生物毒性，有望在生物医学工程领域得到应用。顺便说一下，生物应用领域的大部分需求是针对定制生产的应用，因此生产需要高成型性。能够满足这些要求的三维（3D）打印技术的研究一直在进行。为了在3D打印中安全地将生物质材料用作树脂或生物墨水，需要对制造添加剂进行研究，3D打印是生物医学工程领域广泛使用的一项技术。在本研究中，制造了一种使用基于生物质的树脂的3D打印技术——投影微立体光刻（PμSL）系统。生物质材料被设计为可光固化以用于PμSL工艺。使用基于生物质的树脂研究了各种PμSL工艺参数，以确定3D结构的最佳制造条件。本研究表明基于生物质的树脂可用于PμSL工艺。我们提供了一种将其应用于各种生物医学工程领域的方法。
