Description

一种3D打印用陶瓷粉末材料
技术领域：
本发明涉及3D打印使用材料相关技术领域，具体涉及一种3D打印用陶瓷粉末材料。
背景技术：
3D打印(3DP)即快速成型技术的一种，它是一种以数字模型文件为基础，运用粉末状金属或塑料等可粘合材料，通过逐层打印的方式来构造物体的技术。3D打印技术出现在20世纪90年代中期，实际上是利用光固化和纸层叠等技术的最新快速成型装置。它与普通打印工作原理基本相同，打印机内装有液体或粉末等“打印材料”，与电脑连接后，通过电脑控制把“打印材料”一层层叠加起来，最终把计算机上的蓝图变成实物。
所谓的3D打印机与普通打印机工作原理基本相同，只是打印材料有些不同，普通打印机的打印材料是墨水和纸张，而3D打印机内装有金属、陶瓷、塑料、砂等不同的“打印材料”，是实实在在的原材料，打印机与电脑连接后，通过电脑控制可以把“打印材料”一层层叠加起来，最终把计算机上的蓝图变成实物。通俗地说，3D打印机是可以“打印”出真实的3D物体的一种设备，比如打印一个机器人、打印玩具车，打印各种模型，甚至是食物等等。之所以通俗地称其为“打印机”是参照了普通打印机的技术原理，因为分层加工的过程与喷墨打印十分相似。
虽然高端工业印刷可以实现塑料、某些金属或者陶瓷打印，但实现打印的材料都是比较昂贵和稀缺的。另外，打印机也还没有达到成熟的水平，无法支持日常生活中所接触到的各种各样的材料。研究者们在多材料打印上已经取得了一定的进展，但除非这些进展达到成熟并有效，否则材料依然会是3D打印的一大障碍。
发明内容：

(7)将步骤6烧结的浆料进行装匣钵：先在匣钵底部洒上高熔点金属粉末钼，将坯料放入匣钵内，在用高熔点金属粉末将坯料掩埋，然后放入真空烧结炉中，进行真空烧结炉内：烧结工艺、抽真空、加热到180～300℃保温、保温60～240分钟、放气、再加热到180～300℃保温、保温1～10小时、充氩气风冷，即制备成3D打印用陶瓷粉末材料。
