Stereolithography, the first AM process to be patented and commercialized, is a vat photopolymerization technique.
What is the name of a process in which liquid photopolymer in a vat is selectively cured by light activated polymer reaction?
6.3. – Vat photo polymerization uses liquid photopolymer as the working material. The liquid photopolymer is selectively cured using the process known as light-activated polymerization to generate a 3D component following the path that has been generated by the sliced 3D model.
When was UV resin invented?
It was developed in 1988 by 3D Systems, Inc., based on the work by inventor Charles Hull . Although many other techniques have been developed since then, stereolithography is one of the most powerful and versatile of all AM techniques for polymers.
What is vat resin?
Vat Photopolymerization is a type of additive manufacturing technology that produces 3D objects by selectively curing photopolymer liquid resin using light-activated polymerization.
What is photo polymerization in SLA?
Photopolymerization 3D printing technology encompasses several different process that rely on the same basic strategy: a liquid photopolymer contained in a vat (or tank) is selectively cured by a heat source. Layer by layer, a 3D physical object is built until completion.
Which method of 3D printing uses a liquid plastic as the source material?
Stereolithography (SLA) – Stereolithography makes use of a liquid plastic as the source material and this liquid plastic is transformed into a 3D object layer by layer1.
