3D computer graphics are graphics which are using three dimensional representation of geometric data (by Wikipedia)

Printing process

Printing is a process for reproducing text and images, typically with ink on paper using a print press.

3D + Printing = 3D Printing

3D Printing is a phrase used to describe the process of creating three objects from digital file using a materials printer, in a manner similar to printing images on paper.

Different methods

Selective laser sintering (SLS)

Stereolithography

Fused deposition modeling (FDM)

Laminated object manufacturing

SLS method(not SLS Mercedes)

Selective laser sintering (SLS) is an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering),ceramic or glass powders into a mass that has a desired 3-dimensional shape

SLS method

STEREOLITHOGRAPHY

Stereolithography is an additive manufacturing process using a vat of liquid UV-curable photopolymer ”resin” and a UV laser to build parts a layer at a time.

FDM

Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications

Laminated object manufacturingLaminated object manufacturing (LOM) is a rapid prototyping system developed by Helisys Inc. In it, layers of adhesive-coated paper, plastic or metal laminates are successively glued together and cut to shape with a knife or laser cutter.

What is ABSplus?ABSplus is a production-grade thermoplastic that gives models the ability to perform just like production parts in real-world functional testing.

How it works ?Stratasys FDM (Fused Deposition Modeling) technology provides the foundation for all Dimension 3D printers. Two materials — one for models, one for support — are heated in an extrusion head and deposited in thin layers on a modeling base. The model is precisely built layer upon layer. When the model is complete, the support material is removed leaving an accurate, durable functional 3D model.

What will be in the future?For many products the standard conveyors can be greatly reduced or completely replace by 3D-printer, because the end product - for example, a car - will not be collected from hundreds or thousands of individual parts but will be produced in one process
