123. Rapid prototyping from the virtual

Rapid prototyping's development is very quickly. And it has brought us a big change. So we should know more things about it.

Virtual prototyping is becoming a cost-effective method used in testing new products and systems. It is an integral part of current rapid prototype Shenzhen methods wherein virtual designs created from computer aided design (CAD) or animation modeling software are used and then transformed into cross sections in a still virtual environment.

In the additive fabrication of virtual prototypes, the rapid prototyping (RP) machine reads the data from a CAD drawing, and forms successive layers of liquid or powdered material according to the virtual data received. It slowly builds up a physical model from a series of cross sections.

Rapid prototyping technologies can either be a "dry" or a "wet" process. Most machines create prototype models by solidifying some sort of loose powder, liquid, or semi-liquid material. A machine may be able to cut through adhesive-coated sheets of prototype fabrication material. The dry powdered materials can either be some sort of polymer, powdered metal, or wax. Some machines may even be able to use starch as the building material for forming the prototype model.

Some of the powders used may also require a binder. The liquid materials mainly used are usually photosensitive polymers that solidify when exposed to either a laser or ultraviolet (UV) light. Wet rapid prototype Shenzhen methods generally require a curing phase.
