A nozzle with liquid material can be drawn over an absorbent surface to wick out material, electrostatically pulled from a larger jet orifice, [15] pressurized to stream material or fluid pressure surged to expel short burst of fluid in the form of spray or individual drops. A fountain pen with nib tip is an example of wicking material.
Binder jet 3D printing, known variously as "Powder bed and inkjet" and "drop-on-powder" printing, is a rapid prototyping and additive manufacturing technology for making objects described by digital data such as a CAD file. Binder jetting is one of the seven categories of additive manufacturing processes according to ASTM and ISO. [1]
The process of material jetting, often also called Inkjet 3D printing, is similar to the 2D Inkjet printing procedure. The print head consists of multiple small nozzles which jet droplets of photopolymers on demand. [2] Each nozzle can extrude a different material, which allows for the creation of multi-material parts. [2]
Consequently, the green parts transition into "brown" parts. The debinding process eliminates excess plastic, leaving behind a structure of metal powder. [2] Sintering: The brown parts, now washed, are transferred to a sintering furnace. This furnace adheres to a material-specific profile, depending on the material used.
The largest 3D printer or Additive Manufacturing machine utilizing cold spray can build parts up to 9×3×1.5 m. [7] During the cold spray process, the impacting particles create the layer, whose thickness can differ, based on the spray gun travel speed against the substrate and the feedstock material feed rate, building the structure layer-by ...

WASHINGTON (Reuters) - U.S. private payrolls increased at a moderate pace in November, while annual wages for workers staying in their jobs edged up for the first time in 25 months.
TU/e Built Environment's Rohaco 3D Concrete Printer being extensively used for Concrete Printing Research. 3D concrete printing, or simply concrete printing, refers to digital fabrication processes for cementitious materials based on one of several different 3D printing technologies. 3D-printed concrete eliminates the need for formwork, reducing material waste and allowing for greater ...
