The new slicer , MOSTMetalCura , provides the following novel abilities necessary for GMAW 3-D printing : i ) change the perimeter metric from width to track count , ii ) avoid movement that overlaps previous weld beads , iii ) have infill start immediately after the perimeter finished and in the direction that eliminates translations , iv ) add a variable pause between layers to allow for substrate cooling , v ) configure GPIO pins to turn on/off the welder , and vi ) set optimized wire feed speed and voltage of the welder based on printing speed , layer height , filament diameter , and tool track width .
