What is 3D printing? Three-dimensional printing uses a power-binder technology to print physical models using a water based binders that sprayed though ink jet cartridges, constructing models from plaster or starch powders. During the construction of the models, the models are cover with the powder, and when it has cured, the models are removed and de-powered and ready to use.

Post processing involves other medium to enhance characteristics and functionality. Epoxy resin provides strength; penetration takes about 4 minutes, cure time it takes about 4 hours. CA resin, hard surface coating, penetration takes 1 minute, cure time takes about 3 minutes. Elastomer provides flexibility to the parts and cure time takes about 24 hours. Wax, provides minimal strength with 100% penetration, cure time is about 15 minutes. Painting provides realistic finishing and it can be applied to raw models or after resin infiltration.

Advantages of 3D printing

Speed- 3D printing reduces time to create a part from a day to a few hours. Cost- materials are cheaper so allows customers to make more parts for less money. Versatility- ability to infiltrate parts with a variety of material expanding the range of applications. Colour- 3D printers can create parts from a 24-bit palette of colors, giving it a multiple color prototype. Materials- offer a range of applications. Starch models are combustible at traditional investment casting temperatures. Plaster models maintain their form at moderate temperatures; enable ling the construction of sacrificial molds for pouring low temperatures metals like lead. Z-cast is a based power that is use for pouring aluminum parts.

The invention of 3D printing will bring about a new era of business. A huge change in the United States will be less need for outsourcing. This is due to the ability to manufacture items near or at the place of consumption for the item. This also includes at home business to possibly...
