The advent of 3D printers has been embraced globally within few years of its emergence. The surge in the acceptability of rapid manufacturing RM technology can be attributed to the depletion and cost of natural resources, waste reduction and sustainability criterion of manufactured parts. This rapidly evolving 3D printing technologies is predicted to grow exponentially especially for the manufa...

Chalcographic printer is the name given to a specific type of press which is used to transfer the printing of a metal-based engraved plate onto paper. The printing system consists of two rollers for pressing and carrying a metal plate onto which an engraved inked plate is placed. When the driving mechanism is operated, the pressure exerted by the rollers, also called contact pressure, allows th...

Metal additive manufacturing (AM) has been growing remarkably in the past few years. Thanks to advantages of unmatched flexibility and zero material waste, this clean technology opens door for new design solutions with greater efficiency, which are not possible through conventional machining techniques. In paper, we provide a overview metal AM techniques that can be utilized wide range applicat...

Additive manufacturing (AM), also referred as 3D printing, is a small but fast-growing sub-sector of the industry. Concerns over increasing worldwide energy consumption provides an impetus to quantify use most common forms AM technologies. To date, research efforts have focussed on industrial machines, and little has been conducted numerous low-cost desktop printers. Additionally, there gap in ...

to determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in ardebil agricultural research station for two years (2001 and 2002). the experiment was in a split split splot on the basis of completely randomized block design with three replications. pre-germination and non pre-germin...

Recently, 3D Printing (3DP) has started disrupting transportation worldwide by providing enormous simplifications to requirements, especially in the context of city logistics. In near future, potential exists replace multi-echelon hubs with integrated logistics and printing manufacturing hubs. This study investigates this concept, particularly for healthcare product distribution (i.e., hearing ...

Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

Additive manufacturing (AM) processes are reliable techniques to build highly complex metallic parts. Direct energy deposition (DED) is one of the most common technologies 3D print metal alloys. Despite a wide range literature that has discussed ability DED in printing, weak binding, poor accuracy, and rough surface still exist final products. Thus, limitations printing powder wire indicate pos...

Tempe is a typical Indonesian food which widely consumed by the public as side dish to increase appetite, well snack that has its own flavor for fans. artisans in Karanganyar Village, Secanggang District, Langkat Regency, North Sumatra Province still maintain method of making tempe chips manually printing one while they are dough. will have distinctive taste. This research examines prototype ch...
