Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the material or the laser beam generated. A typical commercial laser for cutting materials involved a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas,[1]leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials.
3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object with material being added together (such as liquid molecules or powder grains being fused together). 3D printing is used in both rapid prototyping and additive manufacturing. Objects can be of almost any shape or geometry and typically are produced using digital model data from a 3D model. There are many different technologies, used in the 3D printing process. The most common by number of users being fused deposition modelling (FDM). Thus, unlike material removed from a stock in the conventional machining process, 3D printing or Additive Manufacturing builds a three-dimensional object from a computer-aided design (CAD) model, usually by successively adding material layer by layer.

What can these do to change the world?
3D printing, or additive manufacturing, has the potential to democratize the production of goods, from food to medical supplies, to great coral reefs. In the future, 3D printing machines could make their way into homes, businesses, disaster sites, and even outer space
The future of laser efficiency lies in automated loading and unloading material storage. SSC are following the technological breakthroughs within the industry and believe that the future may lie in direct diode laser (DDL), with even faster cutting speeds and increased power consumption efficiency. The speeds in which these machines work currently are more pronounced with the thin gauge materials, particularly aluminium.
