摘要:
A selective layer melting or other additive layer fabrication method in which powdered material is fused by heating it with a pulsed laser, the pulses being modulated while the laser is traversing the substrate so as to control the thickness and/or width of the layer being formed. Initial layers of the fabrication structure may be formed more thickly than subsequent layers, e.g. by means of a CW laser, to reduce distortion. This aspect of the invention may be employed independently of the use of a pulsed laser to form the subsequent layers.
摘要(中):
一种选择性层熔化或其它添加剂层制造方法,其中粉末材料通过用脉冲激光加热熔化,脉冲在激光穿过衬底时被调制,以便控制形成的层的厚度和/或宽度 。 制造结构的初始层可以形成为比后续层更厚,例如, 通过CW激光器来减少失真。 本发明的这个方面可以独立于使用脉冲激光来形成随后的层来使用。
