Description

一种提高材料课程教学的3D打印多元相图建立方法
技术领域
本发明属于材料科学与工程中多元相图的技术领域，具体涉及一种提高材料课程教学的3D打印多元相图建立方法。
背景技术
国家大力提倡培养创新型与工匠型人才，高校专业课程教学作为学生最直接接触的教学活动，而有些课程的理论较为复杂，传统的教学方式让学生难以充分掌握扎实的专业理论基础，如：材料科学与工程专业的多元相图教学。在材料学科，掌握相图的分析已经成为学生必不可少的专业素养，多数学生只能掌握二元相图的分析，对于三元及三元以上的相图，则是难以着手。这与课程教学的方式有着直接关系，三维空间的复杂相图难以在教学中形象表达、学生缺乏空间想象能力，导致材料专业本科生的专业理论不足。因此，引入3D打印可拆分式三维多元相图教学用具模型作为创新型、开放型教学课程改革，能够给材料学科的多元相图教学内容提供良好补充，提高跨学科课程实践，为课堂教学注入新活力。
发明内容
本发明的目的是提供一种提高材料课程教学的3D打印多元相图建立方法，采用3D打印成形可拆分式三维多元相图教学用具模型，提高学生的专业基础。
本发明所采用的技术方案是，一种提高材料课程教学的3D打印多元相图建立方法，具体按以下步骤实施：
步骤1，首先对所需三元相图进行分析，三维建模局部相区；
步骤2，将经步骤1建立的模型，采用3D技术进行成形后进行组装。
本发明的特点还在于：
其中步骤1中三元相图分析的具体过程为：
首先对多元相图的进行分析，明确单相区、两相区、三相区的具体分布、微观晶体结构、固液转变线的分布，根据相区的微观晶体结构建立相区的模型填充，然后建立三维实体模型，然后对建立的三维立体模型利用切片软件进行分层切片，获取在不同高度上分层的信息；
其中建立三维实体模型过程具体包括：对每个相区均需单独建模，相图模型的填充运用微观晶体的结构进行宏观填充；
其中三维实体模型的建立采用Solidworks软件、Pro/Engineer软件或Unigraphic软件；
其中步骤2具体内容为：将经步骤1获取的切片分层的信息输入彩色3D打印机中，将经步骤1设计的模型进行打印成形，不同的相区采用不同的颜色，最后进行组装；
其中3D打印机采用彩色树脂为原料，用于区分不同的相区。
本发明的有益效果是：
本发明一种提高材料课程教学的3D打印多元相图建立方法，从三维模型设计出发，并且按相区的晶体结构填充相区的模型、多色彩呈现多元相图教具，为课堂教学注入新活力，帮助学生直观了解多元复杂相图，提高教学质量。
具体实施方式
下面结合具体实施方式对本发明进行详细说明。
本发明提供一种提高材料课程教学的3D打印多元相图建立方法，具体按以下步骤实施：
步骤1，首先对多元相图的进行分析，明确单相区、两相区、三相区的具体分布、微观晶体结构、固液转变线的分布，根据相区的微观晶体结构建立相区的模型填充，采用Solidworks软件、Pro/Engineer软件或Unigraphic软件建立三维实体模型，然后对三维立体模型利用切片软件进行分层切片，获取在不同高度上分层的信息；
其中单相区的晶体结构根据温度的变化会呈现出不同的晶体结构，即可根据微观晶体结构的过度建立宏观尺度的点阵模型结构过度；
其中不同相区的模型需独立建立，独立模型之间根据相图内部分布的具体位置又可拼接在一起，组成多元相图；
步骤2，将经步骤1建立的多个复杂结构的独立模型进行切片分层的信息输入彩色3D打印机中，以彩色的树脂为原料，将经步骤1设计的模型进行打印成形，不同的相区采用不同的颜色，最后进行组装。
其中3D打印的设备采用Stratasys公司的全彩色3D打印机，可同时加载7中材料，制作出各种纹理感或透明效果，让多元相图教具更加逼真；
从相图教具的模型设计和成形过程解释本发明的一种提高材料课程教学的3D打印多元相图教具：三维空间的复杂相图难以在教学中形象表达、学生缺乏空间想象能力，导致材料专业本科生的专业理论不足，本发明提出以3D打印技术成形多元相图教具，按相区的晶体结构填充相区的模型、多色彩呈现多元相图教具，为课堂教学注入新活力，帮助学生直观了解多元复杂相图，提高教学质量。
