Our machines can use nearly any weldable metal – in both wire and powder forms – except for reactive powders (aluminum, magnesium, and titanium, for example).

Tolerances for printed parts are based upon the build strategy, geometry, and deposition rate. While we can achieve +/- .010” on features, most of the time it is faster to avoid using perimeter passes. We recommend overbuilding by .030,” ensuring there is material for post-process machining for the most accurate manufacturing. Machined parts will always be more accurate and have a better surface finish as opposed to a printed part 

Typically to achieve the required tolerances, we recommend overbuilding during the additive process, followed by machining to achieve the desired surface finish and size. To remove fully printed parts from a build plate, a bandsaw or Wire EDM can be used. Heat treatment can also be required depending on the internal stress of the material, how much weld material was deposited, and the required hardness post welding.  

The two biggest operating costs are shielding gas and welding wire. While not a cost-driving factor, consumables such as the copper wire nozzle do have to be replaced periodically.
