Additive manufacturing is the process of building up a 3D component by adding layer upon layer of material deposit. It is also commonly described as “3D printing”. Using a combination of special machines – often referred to as printers – and computer software, complex shapes can be created. It is a technology that has been in existence for 30+ years, but it’s only in recent years that the technique has been more widely used for its versatility and excellent return on investment (amongst other reasons).
Laser additive manufacturing can be achieved using a wide range of materials, including plastics, concrete, metals, glass, food and even body parts – the list is particularly endless and may be restricted by our imagination only! Perhaps most commonly, the process is used with metals; it is metal powders which are an essential part of the process of layer by layer addition of material for various purposes such as the repair/creation of parts, etc. The process is achieved where lasers heat the material, which is held in a cartridge, then superfine layers are placed down in a cross-section. This cross-section is gradually built up from the bottom to the top, with the software instructing the printer where and when to lay down the material.
Additive manufacturing is frequently used in the creation of rapid prototypes through rapid CAD modelling. The AM (additive manufacturing) process is sometimes referred to as the second industrial revolution; such is the expectation of the degree to which it will transform industrial processes.
The benefits of laser additive manufacturing with fiber lasers can’t be underestimated. Here are just a few of the benefits of using this technology:
To read in more detail about the advantages of this technology, visit the benefits and advantages of additive manufacturing and 3D printing.
Many rapid manufacturing processes use industrial Lasers as an energy source. Our Fiber Lasers are an integral element of many metal powder processes and applications. SPI Lasers provide many high quality, reliable lasers to industrial sectors to be used as the energy source in the process, and our Fiber Laser range has become a core part of many metal powder processes. Also, don’t forget that SPI Lasers can be programmed for many other purposes, these include ablation, cleaning, cutting, drilling, engraving, marking and welding – all these tasks are possible on just one SPI laser.
