Also called “additive manufacturing,” 3D printing is a process where a digital file is used to create a solid object. To create the 3D printed object, a process is used where a machine applies a series of layers that eventually result in the creation of an object. Follow along to learn how Cary Products uses 3D modeling to create your product.
The first step features creating a virtual design in a computer via a CAD file. CAD stands for “Computer Aided Design.” The file may be created with a 3D scanner, or a 3D modeling application can be employed for the job. When a 3D scanner is employed, there are different types of technologies that may be used by the 3D scanner. Some of those technologies include:
- Structured or modulated light
- Volumetric Scanning
Seeking to capitalize on the future of 3D printing, some companies have started researching and enabling 3D scanning via their hardware. Companies like Google and Microsoft want to make it so easy to create a 3D model that all a user might need to do is take a picture. There is the expectation that the smartphones that everyone uses today will have eventually have the ability to act as 3D scanners.
3D scanners aren’t that rare today, but they can vary in their price from somewhere around $30 all the way up to professional devices that cost much more. For the person interested in exploring 3D modeling and printing, there are some simple programs that can get the novice 3D printing enthusiast started.
Moving on from 3D Modeling to a 3D Printer
Virtually anyone can set up a 3D printer and create small projects in their spare time. However, there are several methods available that are used by professional manufactures who use plastic molding to create large orders that may contain several thousand separate pieces meant for large-scale manufacturing projects.
The different technologies used in 3D printing are classified by the American Society for Testing and Materials under their “Additive Manufacturing” group. There are several different categories that include:
- Binder Jetting
- Directed Energy Deposition
- Material Extrusion
- Material Jetting
- Powder Bed Fusion
- Sheet Lamination
Using 3D Printing and Industry Growth
Each of the different 3D printing technologies is part of an industry that was measured at over $3 billion in 2013 and was expected to grow to more than $21 billion by 2020. With these technologies, manufacturers can create an amazing array of items from 3D printed prosthetics for human use to the reconstruction of fossils for paleontological study.
One of the fastest areas of growth within the industry is the bio-printing industry where scientists and doctors are engaged in researching new uses for 3D printing technology. Not only has 3D printing become an integral part of prosthetics research, but scientists have also been researching the options for building real body parts made of living cells.
Another industry that has developed a keen interest in 3D printing is aviation, which has used metal additive manufacturing as its primary research focus. NASA uses selective laser melting to 3D print its combustion chamber liners, and GE Aviation has gained approval from the FAA to begin testing a 3D printed jet engine part.
