Robocasting (also known as robotic material extrusion [1]) is an additive manufacturing technique analogous to Direct Ink Writing and other extrusion-based 3D-printing techniques in which a filament of a paste-like material is extruded from a small nozzle while the nozzle is moved across a platform.

Robotic materials are composite materials that combine sensing, actuation, computation, and communication in a repeatable or amorphous pattern. [1] Robotic materials can be considered computational metamaterials in that they extend the original definition of a metamaterial [2] as "macroscopic composites having a man-made, three-dimensional, periodic cellular architecture designed to produce an ...
Hot extrusion is a hot working process, which means it is done above the material's recrystallization temperature to keep the material from work hardening and to make it easier to push the material through the die. Most hot extrusions are done on horizontal hydraulic presses that range from 230 to 11,000 metric tons (250 to 12,130 short tons ...
Amazon has introduced a handful of robots in its warehouses that the e-commerce giant says will improve efficiency and reduce employee injuries. Two robotic arms named Robin and Cardinal can lift ...
Additionally, they reduce the mass of the extrusion carriage because it doesn't have to hold a stepper motor. This allows for faster changes in print head movement direction, increased print speed, increased accuracy, and decreased instances of artifacting or ghosting along the x and y axes.
The Bionic Bar, produced by Makr Shakr, is installed in nine cruise ships of cruise line Royal Caribbean. [10] The company is set to debut in Changi Airport, Singapore, [11] Bali, Olympia, Wa [12] and Dallas in 2024. The company's flagship robot Toni featured in the exhibition "AI: More Than Human" at the Barbican, London in 2019. [13]
Robots were able to perform routine tasks like greeting patients, providing directions, and answering questions during the trials with patients. Robots Created to Help Patients in Hospitals Pass ...
Bar stock is available in a variety of extrusion shapes and lengths. The most common shapes are round (circular cross-section), rectangular, square and hexagonal. A bar is characterised by an "enclosed invariant convex cross-section", meaning that pipes, angle stock and objects with varying diameter are not considered bar stock.
