Abel Azcona's work in Havana.. Process art is an artistic movement where the end product of art and craft, the objet d’art (work of art/found object), is not the principal focus; the process of its making is one of the most relevant aspects if not the most important one: the gathering, sorting, collating, associating, patterning, and moreover the initiation of actions and proceedings.
Modeling is one of the most common techniques for sculpting. It is an additive process in which material is steadily built up to produce the finished figure. Unlike carving, the sculptor often also has the option of correcting mistakes by removing or reshaping the material.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Additive friction stir deposition (AFSD) is a solid-state metal additive manufacturing process that uses a rotating tool to deposit feedstock material onto a substrate. [28] AFSD offers a number of advantages over other metal additive manufacturing processes, including high material utilization, low energy consumption, and the ability to print ...
Stereolithography is an additive manufacturing process that, in its most common form, works by focusing an ultraviolet (UV) laser on to a vat of photopolymer resin. [14] With the help of computer aided manufacturing or computer-aided design (CAM/CAD) software, [ 15 ] the UV laser is used to draw a pre-programmed design or shape on to the ...
An additive process is the generalization of a Lévy process (a Lévy process is an additive process with stationary increments). An example of an additive process that is not a Lévy process is a Brownian motion with a time-dependent drift. [1] The additive process was introduced by Paul Lévy in 1937. [2]
When mixing colored light (additive color models), the achromatic mixture of spectrally balanced red, green, and blue (RGB) is always white, not gray or black. When we mix colorants, such as the pigments in paint mixtures, a color is produced which is always darker and lower in chroma, or saturation, than the parent colors. This moves the mixed ...
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
