Chuck Hull
Chuck Hull (Charles W. Hull; born May 12, 1939) is an American inventor who is the co-founder, executive vice president and chief technology officer for regenerative medicine of 3D Systems. He is one of the inventors of the SLA 3D printer, the first commercial rapid prototyping technology, and the widely used STL file format.

Stereolithography
Stereolithography (SLA or SL; also known as vat photopolymerisation, optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligomers to cross-link together to form polymers. U.S. Patentbr>4,575,330(“Apparatus for Production of Three-Dimensional Objects by Stereolithography”) Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Chuck Hull in 1984 when he applied for a patent on the process, which was granted in 1986. Stereolithography can be used to create prototypes for products in development, medical models, and computer hardware, as well as in many other applications. While stereolithography is fast and can produce almost any design, it can be expensive. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photopolymer
A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light. An example is shown below depicting a mixture of monomers, oligomers, and photoinitiators that conform into a hardened polymeric material through a process called curing. A wide variety of technologically useful applications rely on photopolymers; for example, some enamels and varnishes depend on photopolymer formulation for proper hardening upon exposure to light. In some instances, an enamel can cure in a fraction of a second when exposed to light, as opposed to thermally cured enamels which can require half an hour or longer. Curable materials are widely used for medical, printing, and photoresist technologies. Changes in structural and chemical propert ...

Royal Photographic Society
The Royal Photographic Society of Great Britain, commonly known as the Royal Photographic Society (RPS), is the world's oldest photographic society having been in continuous existence since 1853. It was founded in London, England, in 1853 as the Photographic Society of London with the objective of promoting the art and science of photography, and in the same year, received Monarchy of the United Kingdom, royal patronage from then-Queen Victoria and Albert, Prince Consort, Prince Albert. A change to the society's name to reflect the patronage was, however, not considered expedient at the time. In 1874, it was renamed the Photographic Society of Great Britain, and only from 1894 did it become known as the Royal Photographic Society of Great Britain, a title which it continues to use today. On 25 June 2019, the Duchess of Cambridge, now Catherine, Princess of Wales, became the Society's Patron, taking over from Queen Elizabeth II who had been patron since 1952. A registered Charit ...

IRI Achievement Award
The IRI Achievement Award, established by the Industrial Research Institute (IRI) in 1973, is awarded "to honor outstanding accomplishment in individual creativity and innovation that contributes broadly to the development of industry and to the benefit of society." The recipient is first nominated by an IRI member organization for his or her invention, innovation, or process improvement, and then voted on by a nine-member Awards Committee, led by the immediate past-chairman of IRI's Board of Directors. The bronze sculpture known as the IRI Achievement Award represents the flight of innovation. The artist who designed the sculpture is John Blair.

Additive Manufacturing
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology; in this context, the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise infeasibl ...
