Abstract Scope |
Processing of electrically insulating materials with high temperature resistance is a major challenge in laser-based powder bed fusion (PBF-LB). Glasses are promising material class, which also offer the potential for manufacturing optical or electronic components while having high chemical resistance. Therefore, this paper investigates the processability of soda-lime glass in conventional PBF-LB machines using Yb:YAG- and CO2-lasers. Firstly, the flow properties and particle shape of the glass powder were inspected. Secondly, the influence of laser power, scan velocity, layer height and hatch distance as well as exposure pattern on the manufacturing of single tracks, single layers and finally 3-D-parts were investigated. Furthermore, the platform heating was varied in the temperature range between 250 to 590 °C resulting in increasing relative density for higher temperatures. The geometrical shape and the relative densities of the manufactured parts were analyzed using optical methods. |
