The 3D printing process is becoming more and popular these days due to its advantages over traditional processes. A printer a machine that creates objects from plastic, nylon many other materials. printers are now portable very expensive. By analyzing this problem, we trying design printer. Compared with printers, the cost of much lower. Make low-cost price 15% lower than market. generation mai...

"We have developed a novel approach for the detection of MRI based on optical atomic magnetometry," said chemist Alexander Pines, one of the world's leading authorities on NMR/MRI technology and leader of the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) team. Pines holds a joint appointment as a chemist with Berkeley Lab's Materials Sciences Div. and with UC Be...

A significant factor in Hewlett-Packard’s new Printing Performance Architecture (see Article 1) is the reduction of the processing power embedded in the printer. Using the host PC for all image formatting leaves only motor, print cartridge, I/O, user interface, command, and status functions to be controlled by the firmware. This results in significant cost savings by reducing processor needs an...

We present a new class of models for color printers. They form the basis for model-based techniques that exploit the characteristics of the printer and the human visual system to maximize the quality of the printed images. We present two model-based techniques, the modified error diffusion (MED) algorithm and the least-squares model-based (LSMB) algorithm. Both techniques are extensions of the ...

The release of the open source 3-D printer known as the RepRap (a self-Replicating Rapid prototyper) resulted in the potential for distributed manufacturing of products for significantly lower costs than conventional manufacturing. This development, coupled with open source-appropriate technology (OSAT), has enabled the opportunity for 3-D printers to be used for sustainable development. In thi...

The Cover Feature shows the build instructions for Open Polarimeter (“Opol”) – a high-resolution chemical polarimeter formed from small number of inexpensive optomechanical parts. complete instrument can be assembled scratch in just two days less than US$250, using only 3D-printer and benchtop milling machine. Despite its low cost, Opol achieves high accuracy few millidegrees, comparable to far...
