Benefits of technology

[0010]The main objective of the invention is to provide a method for rapid layered manufacture of objects in titanium or titanium alloys.

Problems solved by technology

These techniques have a disadvantage of high material use of the expensive titanium metal and large lead times in the fabrication.
The technique is thus suited for formation of prototypes and small production series, but less suited for large volume production.
The electron beam technology has a disadvantage of being dependent upon a high vacuum of 10−1 Pa or less in the deposition chamber.

Embodiment Construction

[0052]The inventive features of the invention according to the second aspect of the invention are schematically presented in FIG. 3.

[0053]The figure shows a reactor 1 with an internal closed compartment made by a set of wall elements 6. The wall elements 6 are positioned such that there are no sharp edges, that is, edges with walls angled at angles of 90° or less. All internal wall angles, a, of the reactor chamber are obtuse (larger than 90°). An actuator 2 which controls the position and movement of a support substrate 3 is located outside of the reactor chamber and protrudes through an opening 7 such that the support substrate 3 is located inside the reactor chamber. The opening 7 is closed by an elastic gas tight membrane 8. An actuator 4 which controls the position and movement of a high energy plasma transferred arc welding torch 5 with wire feeder for feeding a wire of the weldable material is located outside of the reactor chamber and protrudes through an opening 9 such that...

Abstract

A method and reactor of manufacturing an object by solid freeform fabrication, especially an object made of titanium or titanium alloys. An objective is to provide a method for rapid layered manufacture of objects in titanium or titanium alloys. A further objective is to provide a deposition chamber which allows prosecution of the method according to the invention.

Description

[0001]This application is a divisional application of U.S. patent application Ser. No. 13 / 390,203, filed Apr. 17, 2012, which was the National Stage of International Patent Application No.: PCT / NO2010 / 000303, filed Aug. 11, 2010, which claims priority to United Kingdom Patent Application No.: 0914301.7, filed Aug. 14, 2009, all of which are incorporated herein by reference. This invention relates to a method and reactor for manufacturing objects by solid freeform fabrication, especially titanium and titanium alloy objects.BACKGROUND[0002]Structured metal parts made of titanium or titanium alloys are conventionally made by casting, forging or machining from a billet. These techniques have a disadvantage of high material use of the expensive titanium metal and large lead times in the fabrication.[0003]Fully dense physical objects may be made by a manufacturing technology known as rapid prototyping, rapid manufacturing, layered manufacturing or additive fabrication. This technique empl...
