Basics
- This is a 3D Printing Method similar to Plastic FDM, but using Metal wire and a heat source
- The heat source can be a welder, a laser, or an electric arc typically
OSE Context
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.
Mig Welder Mod Calculations
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.
Examples/Industry Standards
- Cranfield University is doing work on WAAM. Largest printed part - 6 meters long, 300lb, plain aluminum - [2]
- See their presentation - good insight - [3]
- They are making real structural parts.
