The dot matrix printers of the 1980s, complete with perforated edge paper are what gave way to the sleek 3D printers of today that create items ranging from human organs to medical equipment. 3D printers work like inkjet printers. Rather than ink, 3D printers deposit the desired material in successive layers, thereby creating a physical object from a digital file. Here’s how.
First, a laser beam is sent out by a laser source which solidifies the material. The elevator then rises and lowers the platform that helps to lay the layers. The vat contains the material that will be used to create the 3D object. As parts are layered one on top of the other, this creates the 3D object. Advanced 3D printers are able to utilize one or more materials including plastic, polymers, resin, titanium, and even gold and silver.
3D printing has come a long way since the inception of the technology several decades ago. It is today possible to create almost anything using a 3D printing technology. Some of the coolest things that can be created with 3D printing technology include acoustic guitars, hand-made camera lenses, coffee cups and dishes, fabric, small toys, and 3D printed medical models.
