Description

一种光固化3D打印材料及其制备方法
技术领域
本发明涉及光固化3D打印材料，具体涉及一种光固化3D打印材料及其制备方法。
背景技术
目前，梯度非金属材料产品主要依靠层层压制的方法制造，但当层与层之间的界面是复杂曲面时，例如模仿天然牙齿的多层复杂曲面结构时，该种方法复杂繁琐，且其简单的界面结构，和单一的材料分布控制，无法满足临床精准仿生制造需求。三维喷墨打印技术为复杂梯度仿生材料的制造提供了新的可能，但缺乏配套材料技术。
发明内容
为了克服以上不足，本发明专利提供一种光固化3D打印材料及其制备方法，可满足不同耐磨度、不同颜色和不同弯曲强度的高分子材料一体化打印的需求。
为了达到上述目的，本发明有如下技术方案：
本发明的一种光固化3D打印材料，包括：按重量份，PMMA:50-90份；纳米羟基磷灰石或纳米氧化锆或纳米玻璃纤维或纳米碳纤维:10-50份，共混形成混合液体，加入适宜浓度的染色剂。
本发明的一种光固化3D打印材料的制备方法，有以下步骤：
1)将PMMA:50-90份；纳米羟基磷灰石或纳米氧化锆或纳米玻璃纤维或纳米碳纤维:10-50份置于容器中，共混形成混合液体；
2)在步骤1)的混合液体中加入适宜浓度的染色剂；
3)用喷墨打印机打印形成用于人体或动物体的高分子材料制品。
羟基磷灰石：Ca5HO13P3；
纳米氧化锆为白色固体，分子式ZrO2，分子量123.22，熔点2397℃，沸点4275℃，硬度较大、常温下为绝缘体、而高温下则具有优良的导电性；尤其是在表面涂层等领域有重要的应用价值。
颜色材质：基本材质都是PMMA，聚甲基丙烯酸甲酯是基本材质，能通过调节所添加色料的不同控制其为牙白色或牙龈粉色；例如：A1、A2、A3；B1、B2、B3为牙科常用牙齿颜色；浅粉色、淡粉色为牙龈颜色。
本发明的优点在于：
本发明可满足不同耐磨度、不同颜色和不同弯曲强度的高分子材料制品一体化打印的需求。
具体实施方式
以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例1：本发明的一种光固化3D打印材料的制备方法，有以下步骤：
1)将PMMA:50份；纳米羟基磷灰石或纳米氧化锆或纳米玻璃纤维或纳米碳纤维:10份置于容器中，共混形成混合液体；
2)在步骤1)的混合液体中加入适宜浓度的染色剂；
3)用喷墨打印机打印形成用于人体或动物体的高分子材料制品。
实施例2：本发明的一种光固化3D打印材料的制备方法，有以下步骤：

2)在步骤1)的混合液体中加入适宜浓度的染色剂；
3)用喷墨打印机打印形成用于人体或动物体的高分子材料制品。
实验例：
将本发明的实施例1-3与现有技术比较：本发明快速获取三种不同的耐磨度高分子材料制品，能快速获取三种不同的颜色，能快速获取三种弯曲强度的高分子材料制品。
如上所述，便可较为充分的实现本发明。以上所述仅为本发明的较为合理的实施实例，本发明的保护范围包括但并不局限于此，本领域的技术人员任何基于本发明技术方案上非实质性变性变更均包括在本发明包括范围之内。
