Direct Metal Deposition(DMD) is a rapid prototyping process which can output melting materials the

same time with other materials from nozzle by laser.After solidification,the prototype layer forms.The parts 

will be made after overlapping layer by layer.DMD can create near net shape and controls heat input,which

decreases post processing of the product.

DMD rapid prototyping allows us to monitor and control the height and temperature of the melt pool.A

pyrometer monitor melt pool temperature which allows for consistency and is critical when depositing 

dissimilar or bimetallic metals.Furthermore,it controls the dilution of substrates,even though the deposited

material and substrate material may have very different melting temperatures.

Due to its low prototyping precision but no limited prototyping space,it's often used for manufacturing large 

metal semi-finished components.Differ from conventional plating or coating,direct metal deposition

china rapid prototyping technology also can prolong the lives of components by applying corrosion resistant coatings.

DMD is capable of processing medium to large size parts with multiple materials,which takes a significant

competitive advantage over other additive metal manufacturing technologies such as DMLS and EBM.
