Digital fabrication technology, also referred to as 3D printing or additive manufacturing, creates physical objects from a geometrical representation by successive addition of materials. technology is fast-emerging technology. Nowadays, widely used in the world. has been increasingly for mass customization, production any types open-source designs field agriculture, healthcare, automotive indus...

We present a new approach for estimating printer model parameters that can be applied to a wide variety of laser printers. Recently developed "model-based" digital halftoning techniques depend on accurate printer models to produce high quality images using standard laser printers (typically 300 dpi). Since printer characteristics vary considerably, e.g. write-black vs. write-white laser printer...

3D printer technology employs the Additive Manufacturing (AM) process which is very popular method of layered manufacturing. 3D printer has huge application to manufacture small amount of fresh, customized & durable prototypes in a short time thus the concept of 3D printing technique is also referred to as rapid prototyping (RP) technique. 3D printer is one of the most promising fabrication too...

A printing system enables the printing of multimedia received from a media source that is communicatively coupled to the printer. Based on the received multimedia data, the printing system produces a paper or other printed output as well as a related electronic output. Together, the printed and electronic outputs provide a representation of the multimedia. The printer is also capable of communi...

A comment on ‘Theegarten et al.: Submesothelial deposition of carbon nanoparticles after toner exposition: Case report. Diagnostic Pathology 2010, 5:77’ We read with interest the article by Theegarten et al. [1] which reports on the case of a patient in whose peritoneum were found submesothial aggregates of carbon nanoparticles (CNPs) with a diameter of 31-67 nm. From their literature study and...

Purpose – This paper aims to verify a new method for accurate part manufacturing using a 3D printer. In particular, the direction and position dependence of the printed results are to be verified within the building area. The results of the accomplished experiments are to be used for the computation of new printer adjustments. Design/methodology/approach – Test cubes with a defined edge length ...

A spectral-based six-color printer model was derived in determining the six color separations for an input spectral image that yields the least metameric reproduction relative to the original. Confined by the ink-trapping limitation, the six-color halftone printer modeling effort is a union of ten four-color halftone printer modeling efforts in addition to a four-ink selector. The four-ink sele...

Several methods exist for printer identification from a printed document. We have developed a system that performs printer identification using intrinsic signatures of the printers. Because an intrinsic signature is tied directly to the electromechanical properties of the printer, it is difficult to forge or remove. There are many instances where existance of the intrinsic signature in the prin...
