Background

3D Printing of metals has to date, largely been conducted using powdered materials with low deposition rates and expensive material. Camarc Additve has developed unique wire and arc based technology centered around robust techniques that can accurately deposit material at high speed. Parts can be produced using exotic materials such as Ti6Al4V, Inconel 625, Inconel 718, Invar, and Stainless Steel. These materials can be deposited to aerospace quality expectations at rates greatly exceeding those achievable with powder. Moreover, it has proven possible to deposit, without hot cracking or segregation issues certain problematic aluminum alloys. In other words, without resort to enhancement with additional materials.

The arc based systems being developed can significantly break the paradigms of cost, lead time, size, quality and material certification. Any part that has a significant amount of machining and has geometry that can be produced by arc based methods will see significant reductions in material cost and machining time when compared to machining from billet. These parts will also offer significant reductions in lead time, elimination of tooling costs and increase in material quality when compared to castings.

Being an arc based process size is restricted only be the size of the manipulation equipment.

Camarc can develop the equipment to produce your part or provide you with the plasma arc technology to produce parts on your CNC or robotic positioning system. Camarc is working with several large customers on developing optimized solutions.

History

Founded in the mid 1970's in the UK, Camarc was established as a manufacturer of heavy duty MIG and TIG welding equipment. By the time the company established facilities in the United States in 2005, plasma arc welding had become its main focus, a specialty of its sister company Arc Kinetics. Many pioneering plasma and TIG technologies have been developed and installed in the automotive and aerospace sectors.
