Wire arc allows low feestock cost 3D metal printing of large parts. A spool of MIG wire is $1.15/lb in bulk -[1]. This is relevant to 3D printing towers for wind turbines, see 3D Printed Windmill Tower, or 3D printing entire tractor frames.
Cost of shielding gas is $9/8 hour shift, about $1/hour. Deposition rates go up to 20 lb per hour. See Welding Deposition Rate. This means one spool is used up per 2 hours. $46 in metal, $2 in gas. So about 4% is shielding gas.
