研究用选择性激光烧结（SLS）实现快速铸造的方法和工艺。结果表明，将快速成形与精密铸造结合可以不用模具而获得复杂的铸件，同时降低小批量产品的生产周期和成本，使设计、修改、验证和制造同步。通过若干实例说明快速铸造的特点。
To study the method and process of rapid casting by selective laser sintering (SLS). The results show that combining rapid prototyping with precision casting allows for the elimination of complex castings without the use of molds, while reducing the production cycle and cost of small lots, and synchronizing design, modification, verification and manufacturing. Several examples illustrate the characteristics of rapid casting.
