【Abstract】 Casting is usually used for manufacturing of complex metal parts. It usually need to make its wax patterns, sand moulds, and ceramic cores by die & mold technology, which has a long cycle and high cost. Especially, it is difficult to make some complex structures. This report mainly introduces the powder-bed laser 3 D process for manufacturing wax patterns, sand moulds, and ceramic cores. It includes the materials characteristics, process influences, and performance evaluations. The results show that this technology can manufacture the complex casting moulds rapidly, and the performances meet the requirements of casting.更多还原
