What is 3D Printing Technology ?

• 3D Printing technology is an additive manufacturing process used to construct a physical three-dimensional object from a digital Computer-Aided Design (CAD) model.

• The 3D printing concept was started by Dr. Hideo Kodama, a japanese whi filed the first additive manufacturing patent in 1981.

• 3D printing Technology is a technology that use filament to print an object.

• 3D Printing works by exposing a layer of photosensitive liquid resin to a UV-laser beam; the resin then hardens in the desired pattern, and the object is built layer by layer until it is complete.

List four types of 3D Printing ?

What is Fused Deposition Modeling (FDM) Technology ?

• This technology uses a digital projection screen to project a single image for each layer at the same time across the entire platform.

• Fused Deposition Modeling (FDM) is a trademarked term commonly used by the industry.

• Most advanced technology at an industrial and professional level due to its high quality, reliability, precision and it being designed for intensive use.

• This technology uses a digital projection screen to project a single image for each layer at the same time across the entire platform.
