A 3D printer can develop three-dimensional objects out of various types of materials; the process involves layering the materials layer by layer to form a three-dimensional object. The method is also known as the additive process due to its nature of building an object from scratch instead of the subtractive method of cutting materials, drilling and machining off.
The best 3D printer has the ability to turn digital files containing three-dimensional data into a physical object. These data can be created on a computer-aided design (CAD) or Computer-aided manufacturing program (CAM).
- How 3D printers work solely depend on a variety of technology. 3D printing technology impacts the process in one way or another. The most popularly used technology is fused deposition modeling (FDM). With this technology, the 3D filament is melted but not burnt, then deposited through a heated extrusion nozzle layer by layer.
- Another 3D printer technology is Selective laser sintering which uses a high-power laser beam to fuse particles of materials like plastics and others.
It is evident that depending on the technology you use, 3D printers can use various materials to make a three-dimensional object. With 3D printing, users have the ability to turn ideas and concepts into 3D models or prototypes. It gives the manufacturers the ability to choose what products they want to produce on demand rather than on large runs, this will further improve inventory management and reduce warehouse space.
The aspect of printing on demand is one of the most significant advantages brought about by 3D printing technology. How? It is because you will only need a little space to stock inventory which is quite different from the traditional way of manufacturing. The 3D design file is kept digitally in a virtual library as they are printed using the 3D model as either STL files or CAD, meaning they can be easily located and printed when necessary. If you want to make a few changes to your design, you won’t need to design all over again, but all you need to do is locate the design from the virtual library and then do the simple iterations you want to make. This process saves significant time and cost.
On the other hand, it can also save money and materials as very little raw material is needed compared to the traditional subtractive method. And in the future view, it is said that it will further change the nature of manufacturing, resulting in consumers getting and printing even more complex and sophisticated object than it is now, including electronic devices in their homes.
