DISPOSITIVO E PROCESSO PARA APLICAÇÃO DE CAMADAS DE UM MATERIAL EM PÓ |
摘要 |
<p>A method for applying powder onto a substrate, e.g. to produce three dimensional items secured by laser sintering, has a reciprocating scraper (8) to move excess powder to collecting systems (11) each side of the substrate holder. The item is built up in layers and the collected powder is recycled to the other side of the scraper while the dosing rate is adjusted to ensure an even coating. The powder is pre-warmed during dosing and is subsequently heated to the process temperature. The recycling means comprise two rotating cylinders rotating in opposite directions.</p> |
