At-Line Thermal Conductivity Measurement Applied in Optimization of Additive Manufacturing

This webinar will highlight the importance of representative thermal conductivity data in additive manufacturing processes. Specifically, Laser-Powder Bed Fusion (LPBF) is a process in which a high-powered laser is applied as a heat source to fuse metal powder into a mass that has a desired 3-dimensional shape. The laser selectively scans and fuses powder material on the surface of the powder bed based on the previously generated AMF (or CAD) file. After one layer is scanned, the powder bed is lowered by one-layer thickness, creating a new layer that is scanned. The process is repeated until the part is completed.

It is essential to understand the effective thermal conductivity (and broader related thermophysical properties such as effusivity and density) of the proposed powder stock material in properly understanding the laser sintering process. The powder’s effective thermal conductivity is fundamental to optimizing the performance during heating and cooling during sintering. In properly characterizing the effective thermal conductivity of the powder, improved process control is possible. In testing at-line and non-destructively, the process can be optimized in real time as adjustments are required. C-Therm’s patented MTPS (modified transient plane source) method is the only technique for thermal conductivity method available to allow for fast, at-line and non-destructive measurements of the metal powder material.

The webinar will review recent published works from the National Center for Additive Manufacturing Excellence (NCAME) at Auburn University highlighting application of the C-Therm TCi Thermal Conductivity Analyzer.

This webinar will interest scientists, engineers and researchers in the additive manufacturing sector.
