This paper presents the design and development of plastic waste extruding machine to provide 3D printing filaments. The motivation this research is create a printer filament from using simple components. In addition, another goal redesign an autonomous-extruding manufacture filament. process begins with design, needs analysis, rebuilding electrical assembly, function testing, analysis filament,...

Photocopy documents are very common in our normal life. In India, people are permitted to carry and produce photocopied documents frequently, to avoid damages or losing the original documents. But this provision is misused for temporary benefits by fabricating fake photocopied documents. When a photocopied document is produced, it may be required to check for its originality. An attempt is made...

This paper investigates major issues in developing a new Rapid Prototyping (RP) process and presents a systematic approach to the required R&D. A procedure for simultaneous study of the many inter-related issues, including hardware and software design and development, material selection, and optimization of various variables will be shown using realistic examples from a recently developed RP pr...

Multispectral printer characterization requires an effective model to map the inputs to the printer (i.e., the digital counts of the inks) into reflectance spectra and vice versa. Most of the methods for printer modeling are based on the color mixing model of Neugebauer, but this model, in its original formulation, is a rather poor predictor of the printer's output, since it fails to take into ...

Color laser printers have fast printing speed and high resolution, and forgeries using color laser printers can cause significant harm to society. A source printer identification technique can be employed as a countermeasure to those forgeries. This paper presents a color laser printer identification method based on cascaded learning of deep neural networks. The refiner network is trained by ad...

We develop a computer aided design (CAD) tool for the simulation and testing of a color image printing pipeline. True color images typically have three color planes (red, green and blue) with eight bits of resolution per pixel per image plane. Printing these images involves a binarization process called halftoning which converts each color plane into a binary image for rendering on binary devic...
