Efesto LLC announced that last quarter it closed substantial sales of metal 3D printers, including a state-of-the-art system that sold for a higher price than any other 3D printer ever sold. The company's CEO Ashok Varma said this validated their vision that there is huge demand for large scale metal 3D printing. Efesto supplies large metal 3D printers using Directed Energy Deposition technology and serves industries like oil and gas, defense, aviation and more. Varma added that for the right applications, the return on investment for Efesto's premium equipment can be 1-2 years. Efesto focuses on applications that are difficult or impossible with conventional manufacturing.
