Correlation between pyrometer monitoring and active illuminaton imaging of laser assisted additive manufacturing of stainless steel
Abstract
Laser assisted additive manufacturing which can e.g. be used for manufacturing of 3-D parts from stainless steel powder layer-by-layer by assist of laser beam. Stainless steel is molten selectively with laser beam and solidified layers of material, attached to each other, form desired 3-D structure.Nowadays range of materials that can be used for laser assisted additive manufacturing is widened and high automation level of equipments has made this method more interesting process for manufacturing. This is why also methods to control the process have started to gain an essential role in laser assisted additive manufacturing processes. Control of process parameters is also essential to get good appearance, good quality and good strength properties of work piece still maintaining the optimum processing speed. Control of temperature in of process is most important of all numerous process factors.The objective of this study was to monitor selective laser melting process simultaneously with pyrometer and video camera system with active illumination. Aim of this study was also to find out correlation between phenomena captured with imaging system and pyrometer measurement data.All tests in this study were carried out at Lappeenranta University of Technology with trial set-up of IPG 200 W SM CW fiber laser and a layer of metal powder. An inert atmosphere was simulated by nitrogen gas flow during process. Material used in this study was EOS StainlessSteel PH1.Results indicate that several phenomena observed from video imaging system had correlation to pyrometer measurements. This makes pyrometer monitoring suitable method for controlling laser sintering process.Laser assisted additive manufacturing which can e.g. be used for manufacturing of 3-D parts from stainless steel powder layer-by-layer by assist of laser beam.
