In the world today, technology is advancing each day, and it’s also helping us come up with quicker, better and more efficient methods of doing our work. One of these advancements that we now use today is 3D printing. 3D printing also called additive manufacturing is a method that utilizes a digital design to create a physical item. You can find several 3D technologies and materials, but all use the same principle you to print. They add material layer by layer to turn a digital model into a solid three-dimensional physical object. In this article, we will discuss all you would want to know about 3D printing beginning with the basics before giving more professional knowledge that will be crucial once you begin.
Every 3D print starts with a blueprint which is in the form of a digital 3D design file for a physical object. Attempting to print a physical object without first creating the design file is like trying to print on paper without the text file. The following step is slicing the design file into thin layers and sending it to the 3D printer. The printing procedure will vary depending on the technology used beginning with desktop printers which melt the plastic material as soon as they lay it on a print platform to the industrial devices which use a laser to melt the metal at high temperatures selectively. The time it takes to print is dependent on the size and the objects, and it could take hours.
The materials available also vary in line with the sort of printer used. These materials include metals, plastics, rubber, sandstones, and alloys. There is a growing number of materials that enter the market each year.
Although 3D printing is regarded by most individuals a futuristic idea; it has been around for more than thirty ears. The first 3D process was identified as stereolithography and was invented in 1983. However, 3D printing has gotten a lot of hype today due to the expiry of patents in ’09 that restricted its use to mostly industrial uses. 3D printer revenues have been growing since and as the additive manufacturing patents continue to expire, we anticipate more innovations in the coming years. Today, there are approximately 300,000 consumer 3D printers in use throughout the world.
It’s vital to know that 3D printing is a technology that’s developing rapidly. With this, it has with own advantages over the conventional manufacturing processes. With 3D printing, we can now come up with complex designs which are effortlessly customizable to match any jobs. There’s no need for tools and molds which leads to some decrease in the fixed charges. 3D printing has also made it easier and quicker to prototype and it has a faster and less risky approach to the market.
