Open source arc analyzer: Multi-sensor monitoring of wire arc additive manufacturing

Open source framework for a Broadly Expandable and Reconfigurable data acquisition and automation device (BREAD)

“…Though open source data acquisition (DAQ) systems have been published [16] , [17] , [18] , National Instruments (closed source, proprietary) systems are used extensively in academia for diverse purposes ranging from analysis of agricultural tools [19] and snow analysis [20] to CNC systems [21] and battery research [22] . National Instruments CompactDAQ (cDAQ) [23] systems are often chosen for their flexibility, modular design, and plug-and play operation.…”

“…As with many processes, data acquisition can be an important component of characterizing novel rapid prototyping equipment [17] . In this manuscript, a DAQ system utilizing BREAD componentry will be proposed and constructed for a metal 3-D printer.…”

Low cost 3D printing of metals using filled polymer pellets

“…Technical solutions designed with these principles are particularly useful for academic research activities [53] and for any structure that needs advanced versatile systems that can be modified extensively [54] , [55] , [56] . Good examples of open source designs applied to metal 3D printing can be found in the recent works done on Wire Arc Additive Manufacturing (WAAM) [57] , [58] , [59] . Here, Gas Metal Arc Welding system are associated with 3D CNC system in order to build part by directly depositing fused metal lines.…”

Forming accuracy improvement in wire arc additive manufacturing (WAAM): a review

“…Hossain et al proposed a new online monitoring method (Hossain et al , 2021), wherein ultrasonic sensors were fixed under a substrate to obtain current and gas flow data. The online monitoring system was developed based on electrical, optical and thermal data obtained using a multi-sensor system (Reisch et al , 2020; Xu et al , 2018; Pringle et al , 2020). Using feedback from this system, the process parameters were adjusted in real time, which realised extremely high-precision WAAM.…”
