3D Printing

THE INVENTORThe technology for printing physical 3D objects

from digital data was first developed by Charles

Hull in 1984.

He named the technique stereolithography and

obtained a patent for the technique in 1986.

The same year, he founded 3D Systems and

developed the first commercial 3D Printing

machine.

Prototyping technologies and their base materials

3D Printing (3DP): Various materials, including resins

3D Ceramic Printing: Various clay and ceramic materials

Selective laser sintering (SLS): Thermoplastics, metals, sand and glass

Fused Deposition Modeling (FDM): Thermoplastics

Stereolithography (SL): Photopolymer Laminated object manufacturing: Laminate

sheets, often paper, and glue Electron Beam Melting (EBM): Titanium alloys

Selective Laser Sintering

This is an additive manufacturing technique that uses a high power laser to fuse small particles of plastic, metal, ceramic or glass powder into the desired 3-D shape.

The laser selectively fuses the material by scanning cross sections generated from a 3-D digital description of the part, for example a CAD file.

STEREOLITHOGRAPHY

Stereolithography is a process for

creating three-dimensional objects using

a computer-controlled laser to build the

required structure, layer by layer.

It does this by using a resin known as

liquid photopolymer that hardens when

in contact with the air.

The term “3D Printer” was not used by

that time and the machine was known as

the Stereolithography apparatus.

Because the technology was so new, 3D

Systems delivered the first version of the

machine to only a few selected customers.

New Developments First ever 3-D printed car.

Urbee is the first prototype car ever to have its entire body 3D printed with an additive process. All exterior components, including the glass panel prototypes, were created using Dimension 3D Printers and Fortus 3D Production Systems at Stratasys' digital manufacturing service.

3-D printed Buildings.Architect Enrico Dini is planning to build the

first ever 3-D printed building with the help of fellow architects.
