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.
Material extrusion-based additive manufacturing (EAM) represents one of the seven categories of 3D printing processes, defined by the ISO international standard 17296-2. While it is mostly used for plastics, under the name of FDM or FFF , it can also be used for metals and ceramics.
Additive manufacturing file format (AMF) is an open standard for describing objects for additive manufacturing processes such as 3D printing.The official ISO/ASTM 52915:2016 [1] [2] standard is an XML-based format designed to allow any computer-aided design software to describe the shape and composition of any 3D object to be fabricated on any 3D printer via a computer-aided manufacturing ...
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.
The Tamil Nadu Small Industries Development Corporation Limited (TANSIDCO) is a state-agency of the state of Tamil Nadu, India established in 1970 to promote small-scale industries in the state. [1]
Textiles. The state is one of the largest producer of textile yarns and finished garments, accounting for more than 70% of the national output. The department is responsible for the management of entire textile supply chain including facilitating resources including materials, land and labour, textile machinery, education and research and promotion.

Selective laser melting or additive manufacturing, sometimes referred to as rapid manufacturing or rapid prototyping, is in its infancy with relatively few users in comparison to conventional methods such as machining, casting or forging metals, although those that are using the technology have become highly proficient [weasel words]. Like any ...
Designs tailored for additive manufacturing are sometimes very different from designs tailored for machining or forming manufacturing operations. In addition, due to some size constraints of additive manufacturing machines, sometimes the related bigger designs are split into smaller sections with self-assembly features or fasteners locators.
