3D Printing is now one of the fastest-growing fields due to its uncountable advantages and unimaginable potentials. From developing prototypes to creating replacement parts, from reconstructing fossils to designing customized consumer products, the 3D printing technology uses are expanding each day.
3D printing technology is now playing a significant role in nearly all major industries across the globe, and its impact will keep on growing as more and more people and industries gain access to the amazing 3D printing technology.
What are 3D printers?
3D printers use computer-aided design (CAD) to produce three-dimensional objects. The 3D printed items are made from a variety of materials, including powders, to molten plastic.
Also referred to as – “additive manufacturing,” 3D Printing involves layers of different materials to produce a three-dimensional object. The commonly used layering materials include composites, plastic, and bio-materials; these materials are used to create items of different shapes, sizes, colors, and rigidity.
These printers act similar to 2D inkjet printers and used a layering method to produce the desired design and object. 3D printers create objects from the ground up and stack layers on top of each other until the desired object shape is achieved.
One of the biggest reasons behind these printers’ widespread popularity is the extreme versatility and flexibility of creating various customized objects. From printing consumer objects from plastic-like sunglasses, phone cases, bike handles to utilizing carbon fiber and metallic powders to print extremely strong industrial products – 3D printers have endless possibilities.
How Do 3D Printers Work?
As mentioned above, 3D printers are from the additive manufacturing family, and they utilize a similar printing method as the traditional inkjet printers. 3D Printing is a revolutionary technology that uses a combo of hi-tech software, powder-like manufacturing materials, and precision tools to produce 3D objects from scratch.
The process of 3D Printing begins with making a digital 3D model, which you can develop of download from a 3D model repository. If you are creating it yourself, you will use a 3D scanner, haptic device, app, code, or a 3D modeling software.
3D Modeling Software
There are various 3D modeling software tools that you can use, including software designed especially for industrial use that costs thousands of dollars per year. Nonetheless, there are also open-source software that are available for free.
If you are a new to 3D printing technology and wish to dip your toes in the world of 3D Printing, then we recommend free software that works in your browser. You can find beginner-friendly options that come with instructions and tips to help you along.
Once the three-dimensional model is finished, you will prepare the file to send it to the 3D printer; this process is called slicing.
Slicing is the process of dividing a 3D model into thin horizontal layers using a slicing software. After your file is sliced, it is ready to be sent to the 3D printer through the internet, USB, or SD. The model is then printed as per the sliced layers.
A built-in slicer is also available in some 3D printers in which you can input raw .stl, .obj, or even CAD files.
How Have 3D Printers Revolutionized Various Industries?
With unlimited possibilities, 3D has the ability to fulfill any additive manufacturing role in almost every industry. From being widely used for prototyping, 3D printing technology plays a vital role in producing finished products at a fraction of the product’s actual cost.
As discussed above, 3D printers have revolutionized nearly all industries with its incredibly flexible technology; not only if we talk about the incredible versatility in the usable material options, but also the impressive range of designs and objects that 3D Printing can flexibly print.
3D Printing is a revolutionary technology not only because of its incredible flexibility. But it is also exceptionally accurate and ultra-fast at manufacturing even the most complex designs, making 3D printing technology a promising manufacturing tool for the future with its possibilities still being discovered.
3D printers have also revolutionized prototyping, and it is now being known as the “rapid prototyping technology.” Industries across the globe are now making the best use of the 3D printing tech to produce prototypes within a few hours and at an impressively low cost instead of investing months and millions of dollars on developing prototypes for research and development purposes.
Several businesses worldwide that have been using this technology for years now claim that 3D printer has speeded up their R&D prototyping speed by ten times and lower the cost by five times.
This is fantastic news for nearly all industries across the world. Some sectors that are popularly utilizing 3D printing technology include:
- Customized consumer products, including footwear, furniture, jewelry, decorative pieces, and more.
- Medical products, including dental products, medical equipment, prosthetics, and more.
- Industrial products, including prototypes, manufacturing tools, functional end-use parts, and more.
- Educational products, including learning material, low-budget scientific experiments, and more.
- Architectural, reconstruction, and restoration products.
Top 7 Industries Using 3D Printing
3D printing technology can be found in almost every sector because it offers an innovative solution for modern problems. Following are some of the amazing ways 3D printing is changing lives:
How about 3D Printing a working rocket ship that will take you to space? Printing aerospace technology is now possible thanks to pioneering companies like the California based company Relativity Space. And they are now fully prepared to launch its first conceptualized rocket; the Terran 1that was printed a few days.
The custom printed rocket with fewer parts than an actual rocket is created using proprietary alloy metal. The Terran 1’s total payload capacity is upto 1,750kg.
With the rapidly growing popularity of the 3D printing industry, education institutes are now rushing to make sure that students make most of this cutting edge technology for research and educational purposes.
