3D Printing Technology

A 3D office printer that costs less than $2,000 and produces quality 3D Models.
3D color printer is one of ideal three-dimensional display apparatuses. To obtain distortion free and full-parallax three-dimensional image, two-dimensional images which have horizontal and vertical parallaxes should be printed into very small elementary holograms. Furthermore, the image can be reconstructed by a white light source. The elementary holograms is partitively recorded by R, G, B Laser. So, the reconstructed image can be observed with true color. The light reconstructed from holographic recording material BB-PAN is shifted to shorter wavelength than recording wavelength.
The idea of 3D printing could not possibly be the next big thing in buildings, prefab construction which took the world by storm has yet to make an impact, nothing beats a hand-made house. Personally, I believe all buildings should be constructed with sustainability in mind, not speed. Having said sustainability is an issue, the proposed ‘3d printing’ system does not appears to be environmentally sustainable, huge mechanical system uses ridiculous amount of energy compare to simple manual labor.
