It is a brief seminar on Atomic Diffusion Additive Manufacturing called as ADAM. It is a metal 3D printing process which is highly accurate & efficient.

2. Introduction
Atomic diffusion is a diffusion process whereby the random thermally-
activated movement of atoms in a solid results in the net transport of
atoms.
Atomic diffusion additive manufacturing is a 3D printing
process. It is an intersection of 3d printing and material injection
moulding process.

3. Working
In ADAM the metal powder is binded with plastic and extruded from a hot
nozzle on to a carbon fibre base each layer at a time. Thus, many such
layers form a green part. The green part is sintered to burn the plastic and it
also makes the product very dense and hard. Hence the final product is
prepared with high precesion and great surface finish. Usually, the mixture
has 60% of metal powder and 40% of plastic. Mostly the plastic is used to
create support structures for the complex designs.

6. Materials Used
The materials used in ADAM are
 17-4 Stainless steel, 316L Stainless steel,
 6061 Aluminium, 7075 Aluminium,
 Ti-6AI-4V Titanium,
 625 Inconel,
 A-2 Tool steel, D-2 Tool steel.

7. Applications
The applications of the products of atomic diffusion additive manufacturing
are uncountable. In 3D printing the rapid prototyping is the major application
and also the products such as
• Jet Engines
• Turbine Blades for Energy Production
• Medical Equipment
• Rocket / Missile / Propulsion
• Aircraft frames, structures, and parts
• Tooling Repair and Reconditioning
• Industrial Pump Components
• Cladding of Critical Surfaces for Corrosion or Thermal Barrier Protection

8. ADVANTAGES
• Final product is 23 times stronger than any other manufacturing process.
• The density of metal is very high Approx.9708kg/m3
• Manufacturing cost is very less.
• It is 50 times faster than regular metal 3D printing method.
• The quality of final product is very high.
• The surface finish of the product is extremely fine.

9. Conclusion
• The Atomic Diffusion Additive Manufacturing is an advanced type of 3D
printing for metal.
• The prototypes or working products which are made of this process are
more precise, fast and
• more tougher than any other manufacturing methods.
