What is 3D Printing?

3D printing, also known as additive manufacturing is a method of creating a three dimensional object layer-by-layer using a computer created design.

3D printing is an additive process whereby layers of material are built up to create a 3D part. This is the opposite of subtractive manufacturing processes, where a final design is cut from a larger block of material. As a result, 3D printing creates less material wastage.

How DOES 3D Model work ?

3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling applications or modelers. A 3D modeler uses special software to manipulate points in virtual space(called vertices) to form a mesh: a collection of vertices that form an object.

    There are Several Types of 3D Printing Model

• Stereolithography (SLA)
• Selective Laser Sintering (SLS)
• Fused Deposition Modeling (FDM)
• Digital Light Process (DLP)
• Multi Jet Fusion (MJF)
• PolyJet
• Direct Metal Laser Sintering (DMLS)
• Electron Beam Melting (EBM)

Advantages

1. Less waste
2. Reduce production time
3. An enhanced competitive advantage
4. Reduce errors
5. Confidentiality

Disadvantages

1.  Initial costs of printer
2. Post processing
3. Printing time
4. Special skill required for 3D models
5. Manufacturing Job Losses
