G+_Eddie Foy Posted June 16, 2015 Share Posted June 16, 2015 I've never trusted sintering. Very brittle and porous. But frigging COOL! http://tinyurl.com/qzvvupt http://tinyurl.com/qzvvupt Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted June 17, 2015 Share Posted June 17, 2015 I think I've seen this before. They use mig welders to print metal. Sorry in advance for my rant. I've been bottling this in for quite a while. How stupid. This will cost more in energy and shielding gas than normal techniques would. Like Eddie Foy said, it's going to be brittle. Even if the metal is normalize, a process that requires heating the metal to 800-900 degrees fahrenheit, the carbon content of welds is very difficult to control. And how are they going to power it? Are they tying into the powerline, or are they going to run noizy generators. And what happens if it rains. Will the robot just weld over rust? To me, it looks like "because we can" technology rather than anything that will actually be useful. Link to comment Share on other sites More sharing options...

G+_Larry Havenstein Posted June 19, 2015 Share Posted June 19, 2015 It wouldn't be so bad if you annealed the project after. But that's not how most sintered parts are treated. Link to comment Share on other sites More sharing options...
