3D laser printing has entered 3D Printing Marketplace the mainstream with everyone from students, to artists, to small businesses jumping on the 3D laser printing bandwagon. Though for many of us the technology is relatively new, 3D laser printing or "additive manufacturing", as it can also be known, began in the 70s and 80s, with the efforts of scientists and grad students to find a way to more efficiently and economically manufacture goods on a tiny scale.

The core manufacturing processes - casting/molding, forming, joining and machining - have not been replaced by 3D printing, as you might speculate, but have simply been scaled down through the adaption of new techniques in manufacturing. New methods for solid modeling have allowed researchers to translate 3-D geometries into mathematical terms, which enabled them to end up being the instructions for equipment control systems.

As additive manufacturing has evolved, accepting new processes and advances in solid manufacturing, the technology has expanded to supporting rapid fabrication from digital models or templates and a selection of geometries that surpasses the capabilities of other methods.

The lion's share of the additive manufacturing techniques that produce up the foundations of the technology were invented and patented in the 80s. To higher understand 3D laser printing today, let's review some of the components that resulted in creating it. In the first place, "additive manufacturing", simply put, is a procedure of creating something 3d by literally layering materials upon one another following a digital design or template. What follows is really a brief breakdown of a number of the original 3D printing or additive manufacturing techniques and processes:

Stereolithography, sometimes called vat photopolymerization, is definitely an additive manufacturing procedure that uses resins and lasers to construct 3D objects. Selective laser sintering (SLS), also called powder bed fusion, works on the computer-controlled laser (e.g., a closed off CO2 laser) to selectively "sinter," or fuse, cross-sections of powder into a solid. Sheet lamination, also called laminated object manufacturing, is the procedure of cutting a thin sheet of paper, plastic or metal into an ideal shape with a laser, repeating this and bonding each layer upon the prior one. Material extrusion functions by pushing liquid plastic or metal out through a nozzle, carrying out a path on a digital map. 3-D printing, also referred to as binder jetting, involves repeatedly setting up layers of powder and then squirting liquid binder on the areas to be solidified to create 3-D objects.

There several companies providing SLM technology, such as for instance Coherent, as a result of SLM's ability allow highly accurate, smooth, and consistent components with a wide variety of materials., that has resulted in their utilization by a variety of industries, such as for example, automotive design, heavy equipment, aerospace, defense, medical, electronics and consumer products and government research.
