METHOD AND DEVICE FOR PRODUCING METALLIC AND NON-METALLIC FUNCTIONAL PROTOTYPES |
摘要 |
<p>The invention relates to a method for producing functional prototypes under a process gas atmosphere, whereby powder is deposited in layers on a construction platform in a processing chamber (2). A temperature cycle which effects a partial or complete melting of the powder is generated by means of laser radiation (1) at points predetermined by CAD data. In order to produce faultless and functional prototypes with an exact size, the invention provides that a process gas flows through the processing chamber (2) from underneath through a solid gas-permeable medium (3) and the process gas is carried away downstream from the gas-permeable medium (3) via a gas-permeable outlet (8).</p> |
