| Popis: | In laser micro sintering (LMS), good densification and low porosity of sintered material is often desirable for good mechanical properties. Recently, a novel LMS process, with the name of “double-pulse laser micro sintering” (DP-LMS), was proposed by the corresponding author. DP-LMS utilizes laser pulse group(s) consisting of “sintering laser pulse(s)” followed by “pressing laser pulse(s)” at a suitable delay time. This reported work has preliminarily demonstrated that, under the studied conditions, DP-LMS can produce an improved sintering result than those by LMS under similar conditions without using the “double-pulse” approach. The potential underlying mechanism has been discussed. |
