Metal Additive Manufacturing Processes

Additive and additive manufacturing processes based on heat deposition.

Metal additive manufacturing processes.

3d printing or additive manufacturing is the construction of a three dimensional object from a cad model or a digital 3d model. Over the past twenty years a number of additive manufacturing am or solid free form sff manufacturing processes have been developed for the purpose of producing structural metallic parts directly from their computer aided design cad specification. Classification is also possible by the group of. A key driver in this respect is the ability to produce geometrically complex and innovative products that are laborious time consuming restrictive and cost prohibitive with conventional manufacturing processes.

The term 3d printing can refer to a variety of processes in which material is deposited joined or solidified under computer control to create a three dimensional object with material being added together such as liquid molecules or powder grains being fused. Systems can be classified by the energy source or the way the material is being joined for example using a binder laser heated nozzle etc. Metal additive manufacturing 3d printing processes. The two processes ge offers with in the pbf category recognized by the american society for testing and materials astm include.

Across many industry sectors there is a continued drive to adopt metal additive manufacturing am for production applications as an alternative to traditional fabrication processes. Metal powders the raw materials. The lattice shrouding the rocket motor acts as a support structure during the additive manufacturing process allowing consecutive layers of metal powder to be melted into place without deformation. Direct metal laser melting dmlm electron beam melting ebm binder jetting.

In addition this level of precision is available at competitive prices allowing for reliable and cost efficient production. 3deo inc a metal additive manufacturing technology company based in los angeles california usa has published three guides that look at various aspects of metal additive manufacturing.
