RAPID prototyping, ENGINEERING equipment, MACHINE design, PRINTING, and SINTERING
The article presents survey findings on the capability of rapid-prototyping (RP) technique for micromolded components in a machine design in the U.S. The gathered data primarily focuses on the dimensions, features and performance of various RP technologies, considering the technology requirement in the medical, optical and microelectronics industries. Among the assessed RP tools include stereolitography, 3D printing or inkjet printing, and selective laser sintering.
METAL powders, POWDER metallurgy, SINTERING, and IRRADIATION
The particularities of the selective laser processing of single-component metal powder layers were investigated, especially the occurrence of the balling-processes under different processing conditions. During laser processing, sintered, semi-sintered/semi-melted or completely melted cakes can be formed. Size and shape of the laser processed parts can change depending on the energy and time parameters of the laser irradiation and on the properties of initial powder layers. [ABSTRACT FROM AUTHOR]
