What is vat in photopolymerization?

Vat polymerisation uses a vat of liquid photopolymer resin, out of which the model is constructed layer by layer. An ultraviolet (UV) light is used to cure or harden the resin where required, whilst a platform moves the object being made downwards after each new layer is cured.

What is vat photopolymerization used for?

Vat photopolymerization processes are ideal for creating highly accurate parts with fine details and smooth surface finishes. Common applications are seen across the medical and dental industries, some of the most common being surgical learning tools, facial prosthetics, and hearing aids.

What is a resin vat?

Vat polymerisation uses a vat of liquid photopolymer resin, out of which the model is constructed layer by layer. An ultraviolet (UV) light is used to cure or harden the resin where required, whilst a platform moves the object being made downwards after each new layer is cured.

Is a vat a container?

a large container, as a tub or tank, used for storing or holding liquids: a wine vat. Chemistry. a preparation containing an insoluble dye converted by reduction into a soluble leuco base.

What are the types of polymerization?

There are two basic types of polymerization, chain-reaction (or addition) and step-reaction (or condensation) polymerization. One of the most common types of polymer reactions is chain-reaction (addition) polymerization. This type of polymerization is a three step process involving two chemical entities.

What is polymerisation give example?

These monomers add together to form a long chain to form a product with specific properties. This whole process of formation of polymers is polymerization. Polythene and Nylon 66 are some examples of polymers.
