3D printing uses computer-aided design (CAD) to create three-dimensional objects through a layering method. Sometimes referred to as additive manufacturing, 3D printing involves layering materials, like plastics, composites or bio-materials to create objects that range in shape, size, rigidity and color.
Three-dimensional (3D) printing is a practical manufacturing method that allows us to transform objects designed in the digital environment into physical objects using layered manufacturing methods. ... Three-dimensional printing applications are spreading rapidly in many areas of the medical sector.
3D printing, also known as additive manufacturing, is a method of creating a three dimensional object layer-by-layer using a computer created design. 3D printing is an additive process whereby layers of material are built up to create a 3D part. ... As a result, 3D printing creates less material wastage.
3D printing applications that are used in construction include extrusion (concrete/cement, wax, foam, and polymers), powder bonding (polymer bond, reactive bond, sintering) and additive welding. 3D printing in construction has a wide array of applications in the private, commercial, industrial and public sectors.
What are the Pros of 3D Printing?
Materials such as wood, cloth, paper and rocks cannot be 3D printed because they would burn before they can be melted and extruded through a nozzle.
There are several types of 3D printing, which include:
A major price milestone was then reached in 2007 when 3D Systems released the first 3D printing system under $10,000. This still was not low enough to allow widespread consumer use, but it put the industry in a position of pressure to bring prices down to consumer friendly levels.
ABS filament is the most commonly used 3D printing plastics.
Pros and Cons of 3D Printing
Companies like Ford, Volvo, and BMW really uses 3D printing for rapid prototyping, experimental parts, and creating jigs and fixtures for manufacturing. Mercedes-Benz which is currently pioneering this niche among other truck producers, and makes more than 100 000 printed prototypes each year.
In education, 3D printing technologies facilitate improved learning, skills development, and increased student and teacher engagement with the subject matter. Furthermore, 3D printing sparks greater creativity and collaboration in solving problems.
