Study on the Preheating Device by Conducting Heat and its Effect in Directive Sintering Metallic Parts |
| |
| Abstract: | The idea of applying with the conducting heat to preheating powder bed in the SLS system was presented and the preheating device was designed. The metallic part was made with this kind of the preheating device. The results show that the device has the advantages as follows: the heating power distributing is very uniform; the total power is small; the efficiency of the power is high; the heat insulation structure is reasonable. And it satisfies the demand of SLS system for preheating to sintering metal powders. |
