Abstract Scope |
Selective laser flash sintering (SLFS) is proposed as a method for directly additively manufacturing ceramics without the need for a polymeric binder. Understanding the onset of the flash event is essential in SLFS because it is necessary to interrupt the flash before thermal runaway occurs. Successful development of a non-contact method for detecting the onset of SLFS is needed to allow a repeatable additive manufacturing process. A high-speed camera is considered in this research for its ultra-high frame rate and ability to measure temperatures from light emission from the sample surface. Experiments are conducted using alternating electric fields in the SLFS system to determine the sensitivity of this technique for detecting the onset of SLFS. |
