3D printing is when you take a digital file and "print" it into a 3D object. The printer does this by adding small layers of material on top of one another in a successive manner until the object has been completed. Material includes plastics, composites, and bio-materials. This kind of printing was invented in Japan in the early 1980s.The 3 different types of 3D printers include: Stereolithographic(equipped with laser that forms liquid resin into plastic, Selective laser sintering(turns powder into objects), and fused deposition modeling (release melted thermoplastic filaments with form layers).

Currently, 3D printers are incredibly beneficial and have many usages. They allow buisnesses to build prototypes at a more cheaper and faster rate. Some buisnesses claim that they make the process 10 times faster and 5 times cheaper than the normal R&D processes. Buisnesses don't just use 3D printing to make prototypes, but also use them for finished projects. Many products we see such as eyewear, footwear, and furnature can be made with 3D printing. In schools, 3D printing allows for hands-on learning. Click Here
The 3D printing industry is predicted to reach 84 billion dollars by 2029. In the future, even homes and buildings could be made with 3D printing. As costs of 3D printers fall, they'll be more available for the use of modeling in the future. The accuracy of manufacuring makes it a good tool for future manufacturing. 3D printing doesn't leave a lot of waste, so itcould be tool contributing to a more sustainable future. Click Here
