Additive Manufacturing and 3d Printing:
Three dimensional objects are constructed through layered development framework, in which the object is manufactured one layer at a time.
A graphical data input is downloaded onto a computer which then dissects the information into different pieces which can be separated into different layers. After the layers have been configured, the computer then sends the information to 3d printing machinery that applies the proper raw materials to construct the object. The 3d printer then continues to add the raw material, layer by layer, until the full object has been created to meet the design and criteria requirements.
A process by which digital 3D design data is used to build up a component in layers by depositing material.
Builds up components layer by layer using materials which are available in fine powder form. A range of different metals, plastics and composite materials may be used.
The system starts by applying a thin layer of the powder material to the building platform. A powerful laser beam then fuses the powder at exactly the points defined by the computer-generated component design data. The platform is then lowered and another layer of powder is applied. Once again the material is fused so as to bond with the layer below at the predefined points. Depending on the material used, components can be manufactured using stereolithography, laser sintering or 3D printing.
EOS Manufacturing Solutions:
Additive Manufacturing (AM) is an appropriate name to describe the technologies that build 3D objects by adding layer-upon-layer of material, whether the material is plastic, metal, concrete or powder.
Once a CAD sketch is produced, the AM equipment reads in data from the CAD file and lays downs or adds successive layers of liquid, powder, sheet material or other, in a layer-upon-layer fashion to fabricate a 3D object.
Parts are built by melting thin layers of powder. Material is added instead of removed, as is the case in traditional machining.
Each layer is melted to the exact geometry defined by a CAD model. Additive Manufacturing allows for building parts with very complex geometries without tooling, fixtures and without producing any waste material.
3D printing or additive manufacturing is a way to build real objects from digital files. The printer converts a software blueprint into slices and deposits layer after layer of plastic, metal or other composites until the finished product is formed.

Common Terminology Associated With Additive Manufacturing:
Stereolithography - A technique or process for creating three-dimensional objects, in which a computer-controlled moving laser beam is used to build up the required structure, layer by layer, from a liquid polymer that hardens on contact with laser light.
Selective Laser Sintering - An additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
Fused Deposition Modeling - FDM works on an "additive" principle by laying down material in layers; a plastic filament or metal wire is unwound from a coil and supplies material to produce a part.
Rapid Prototyping - A group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data.
