What is stereolithography who invented it and when?

The term “stereolithography” was developed in 1986 by Chuck Hull when he patented the process. He defined this technology as a method of creating 3D objects by successively printing thin layers cured by ultraviolet light.

What is made from stereolithography?

Stereolithography (SLA) is an industrial 3D printing process used to create concept models, cosmetic prototypes, and complex parts with intricate geometries in as fast as 1 day. A wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SLA.

What is the process of stereolithography?

Stereolithography is a 3D Printing process which uses a computer-controlled moving laser beam, pre-programmed using CAM/CAD software. Stereolithography (SL) is an industrial 3D printing process used to create concept models, cosmetic – rapid prototypes, and complex parts with intricate geometries in as fast as 1 day.

Who was the first inventor of stereolithography technology 3D printing Mcq?

Who was the first inventor of Stereolithography technology of 3D printing? Chuck Hull (Charles W. Hull; born May 12, 1939) is the co-founder, executive vice president and chief technology officer of 3D Systems.

When was SLA printer invented?

The first commercial SLA 3D printer, the SLA-1, was released by his company in 1988. But SLA wasn’t the only additive manufacturing process being explored during this time. In 1988, Carl Deckard at the University of Texas filed the patent for Selective Laser Sintering (SLS) technology.

What is 3D print resin made of?

In essence, 3D printer resin is a liquid solution that’s made of a variety of monomers and oligomers. Photopolymerisation ensures that the short carbon chains that make up monomers and oligomers cross-link and form polymers – a material that is composed of repeating units that make up large molecules.

Which material is used for SLA process?

SLA 3D printers use light-reactive thermoset materials called “resin.” When SLA resins are exposed to certain wavelengths of light, short molecular chains join together, polymerizing monomers and oligomers into solidified rigid or flexible geometries.

How is 3D resin made?

The process beams ultraviolet (UV) light into a tank of liquid, resin, triggering a reaction that solidifies the resin into a hard plastic. This photo-polymerization happens in a small volume thanks to the narrow ultraviolet beams.

Why are photopolymers essential for stereolithography?

In the early 1980s, Japanese researcher Hideo Kodama invented the stereolithography by using ultraviolet (UV) light to cure photosensitive polymers. Photopolymers are sensitive to ultraviolet light, so the resin is photochemically solidified and forms a single layer of the desired 3D object.

What is additive manufacturing technology?

Additive manufacturing is the process of creating an object by building it one layer at a time. It is the opposite of subtractive manufacturing, in which an object is created by cutting away at a solid block of material until the final product is complete.
