Energy Consumption in Metal Additive Manufacturing
Mar 28, 2019Multilaser powder bed systems use about 1kw of laser power but print at speeds 25100x slower than wire processes. Most of the energy consumption in Binder jetting happens in the secondary, furnace sintering step. It is important to compare these metal AM process energy consumptions to conventional alternatives like machining.

How zirconium is made
The only refining process used on baddeleyite involves grinding the gravel or sand to a powder and sizing the powder with different sized sieves. All zirconium oxide that comes from baddeleyite is used for refractories and, increasingly, advanced ceramics.

Molybdenum Processing
The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.

Powder metallurgy
Mar 01, 2004Iron powder is commonly used for sintering Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.
