快速打样在空心叶片上的应用用激光立体印刷术进行快速打样的一个优点是可以用来制造带冷却孔道的样件，因此在英国罗·罗公司受到重视。该公司用这种技术来制造带冷却孔道的涡轮叶片，这种叶片虽不能直接用于发动机，但可用来对涡流叶片的气动力进行研究。一块长３５（ｈ...
Rapid proofing on hollow blades One of the advantages of rapid proofing with laser stereo printing is that it can be used to make samples with cooling tunnels and is therefore valued by the UK firm Luo Luo. The company used this technique to make turbine blades with cooling channels that could not be used directly in the engine but could be used to study the aerodynamic forces on the vortex blades. A long 35 (h ...
