Seven Practical Applications of 3D Printing

A few decades ago, nobody ever thought that two-dimensional printing using desktop printers, let alone 3D printing, would be possible. But the impossible eventually became possible, and 3D printers are becoming part of office networks. It would not be long before these special printers would find their way into households as well and are being used by ordinary consumers.

The concept of 3D printing may sound like something out of Star Trek, but it is definitely real. Basically, it works using inkjet technology, and fine powder such as plaster, resin and cornstarch are used to build 3D models layer by layer in cross-sections. Many people across many fields of expertise have actually found practical uses for 3D printing. A few examples of these practical applications of 3D printing are as follows:

1. Engineering. Engineers always need to create prototypes of whatever products or designs they are working on. In the old days, prototypes can take weeks and a lot of manpower to create because it involves a lot of cutting and piecing together paper, wood and other materials to create the required prototype. Through 3D printing, engineers only need to make a 3D graphic image of the design they are working on and have it rendered using a 3D printer.

2. Architecture. Just like with engineers, architects need to create mockups of their designs. 3D printers allow them to come up with these mockups in a short period of time and with a higher degree of accuracy. These 3D models also make it easier to visualize a design rather than just by looking at plans and drawings.

3. Advertising and marketing. Advertisers and marketers need their clients to have a more solid idea of the products they are selling. Creating 3D models of their products gives them an edge that can boost their sales.

4. Education. Learning needs to be more visual in order to become effective, especially in subjects such as chemistry, engineering, history, physics, general science, among many others. 3D printing allows teachers to create more accurate visual aids for their lessons, and these visual aids can entice students to learn more about the subject matter.

5. Medicine. There are many medical cases where surgical procedures can be a touch-and-go thing. They can be so complicated that a single error can lead to failure and loss of life for the patient. Many surgeons now use 3D renderings of the part of their patient’s body that they need to operate on to practice on the procedure they need to perform before actually performing them. It gives them more confidence and increases their chances of success in the operation.

6. Archaeology and paleontology. These two fields both deal with relics and remains that may be too delicate and valuable to handle. In order to prevent damage to these relics and remains when they are being handled or studied, 3D replicas are made instead. This also allows more scientists to study a single object at the same time.

7. Forensic pathology. Those of us who are fans of crime shows such as CSI and NCIS would know that investigating a crime scene and examining evidence can be a very complicated process. 3D printing helps a lot in such forensic investigations.

There are so many applications of 3D printing today. They may have been part of yesterday’s science fiction, but now, they are certainly part of our reality and will continue to do so into the future.
