Figure 1. A bracket and metal 3-D printer (A) 3-D model; (B) metal 3-D printed part on substrate, where the substrate is a model for an existing part; and (C) the set-up of an open-source GMAW-based metal 3-D printer. Figure 1. A bracket and metal 3-D printer (A) 3-D model; (B) metal 3-D printed part on substrate, The design of the low-cost open-source metal 3-D printer [5,7] is inspired by the Rostock style delta RepRap [27]. However, it uses a stage printing setup allowing for stationary heavy toolheads [28,29] while automatically controlling the movement of a substrate with three-axis control under a fixed perpendicular weld gun printer head (Figure 1C). The motion controls are managed by an Arduino-based microcontroller and the free and open source 3-D motion control software called Franklin [30]. Franklin also controls the welder (e.g., on for printing and off for traveling). A Millermatic 190 welder (Miller, Appleton, WI, USA), ER70S-6 steel wire, and shield gas of RC25 (75% Ar and 25% COz2) were used for the experiments. Printing is performed on a re-useable substrate of low carbon steel with dimensions of 127 x 127 x 6 mm. The stage that holds a substrate is covered with cement board and then an aluminum plate (Figure 1C) to accelerate the transfer heat away from the printed part.
