This high risk, high potential research is focused on the design and execution of experiments to study a new process in layered manufacturing. The process is based upon bulk sintering of powder layers using radiation, as an alternative to selective laser sintering (SLS).The process is anticipated to present better dimensional control, reduced machine cost, and reduced fabrication time in the production of 3-D structural components. This is a major deviation from the traditional research on powder sintering and poses the risks associated with new and untested phenomena, as it requires sintering inhibition in selected areas.

这项高风险、高潜力的研究集中在实验的设计和执行上，以研究分层制造的新工艺。 该工艺基于使用辐射对粉末层进行批量烧结，作为选择性激光烧结（SLS）的替代方法。该工艺有望在生产三维结构部件时提供更好的尺寸控制、降低机器成本和缩短制造时间。这是对粉末烧结传统研究的重大偏离，并带来了与新的和未经测试的现象相关的风险，因为它需要在选定的区域抑制烧结。
