摘要

利用选择性激光烧结快速成型技术

在自行开发的快速成型机上以CO

激光对SiO

浆料进行烧结

经由层状堆栈加工后

制备出了外形复杂的三维SiO

陶瓷喷嘴生坯.利用扫描式电子显微镜和能谱分析仪对生坯进行了微观结构和成分分析

结果显示:在激光功率为7 W、扫瞄速度为160 mm/s和激光扫描分辨率为250次/(25.4 mm)的优化条件下

SiO

粉末可激光烧结形成的最小层厚为100 μm

且层堆栈情况良好

没有分层现象

可制造出纯SiO

陶瓷喷嘴

抗弯强度接近最大值.

Abstract

Selective laser sintering technique is adopted to sinter SiO

slurry by CO

laser on a home-made rapid prototyping machine. A three-dimensional green body of a complex-shaped ceramic nozzle is constructed by layer-additive technology. SEM and EDS are used to analyze the microstructure and composition of the green body. The results show that the silica powder can be sintered to form green part with a smallest layer thickness of 100 μm under optimal conditions for laser power of 7 W

a scanning speed of 160 mm/s

and a scanning resolution of 250 dpi. Therefore

the pure ceramic nozzle with good layer addition and without layer separation is fabricated

whose bending strength approaches the maximum.
