Abstract
A contact tip assembly having an electric contact unit containing a contact tip with an electric energy source, where the electric contact unit is positioned at a distance away from the outlet opening of a guide.
Claims25
A contact tip assembly, comprising:
- a guide having a longitudinal center axis, a first end, and an opposite second end, and a center bore extending and running along the longitudinal center axis of the guide from its first end to its second end;
- an electrically insulating lining inside of the center bore and extending at least from the first end to the second end of the guide;
- and
- an electric contact unit containing a contact tip in electric contact with an electric energy source, the electric contact unit arranged to contact a metal wire with the contact tip past the second end of the guide.
1 more element
A method for providing an electric current to a metal wire during manufacturing of a three-dimensional object of a metallic material by solid freeform fabrication, comprising:
- feeding a metal wire through a guide;
- providing a contact tip that is separate and apart from the guide;
- and
- contacting the metal wire with the contact tip after the metal wire has passed through an end portion of the guide.
1 more element
A system for manufacturing a three-dimensional object of a metallic material by solid freeform fabrication, comprising:
- a guide for guiding a metal wire into position above a base material;
- a contact tip arranged to contact the metal wire past an end of the guide;
- a welding torch to melt the wire and cause a metallic material to drip onto a base material;
- and
- a computer model of the object to be formed to define a deposition profile such that a physical object is built by fusing successive deposits of the metallic material onto the base material.
