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)
Disadvantages
- Initial costs of printer
- Post processing
- Printing time
- Special skill required for 3D models
- Manufacturing Job Losses
