As the 3-D revolution has come to market with movies and television sets, it has also invaded the printer industry. These 3-D printers are priced between $14K-$20K and are pretty cool making a CAD drawing come to life just like magic. How this works is that fine powder consisting of plaster, corn starch and resins are built layer by layer, bonded by an adhesive from the inkjet print head, until the final physical model is built. There is no paper involved.
3-D printing is not a joke and printer companies believe the time is right for this technology to become mainstream. Hewlett-Packard, well-known for its home PCs and ink printers, sees a huge potential customer base of commercial and industrial designers who are already creating 3-D models on their computers. There HP recently partnered with a smaller company, Minneapolis-based Stratasys, to sell commercial 3-D printers under the HP brand.
