How do 3D printers work
Most of us may have had days of imagining robots, action figures, jewelry, toys, and lots of other stuff and putting them on paper. Back then, sketching or drawing these ideas were enough to entertain and exercise our imagination, but wouldn�t it be cool to actually see these things come to life? Perhaps the idea of having user-friendly technology that transforms ideas in 3D versions could appear impossible or too complicated-but that was decades ago. These days, with all the technological advancement coming out nonstop every day, more things are possible, and that includes having your own design come to life. Product design is now more accessible, and could happen in the comforts of your home or office. This feature is all about 3D printing, a kind of technology that will allow you to create three-dimensional solid objects.
What is 3D printing?
In 3D printing, the construction of an object is done through an automated process. This new technology is getting more and more popular these days, and both hobbyists and experts are taking notice. Basically, it is a process in which materials such as plastic, resin, polymer, or metal are used to create a design that you made yourself. What starts off as a digital using a Computer-Aided Design (CAD) or 3D-scanned file becomes a three-dimensional object. You can print just about anything using a 3D printer, and below are the things that you must know about this amazing product.
What�s the Printing Process?
3D printing undergoes a process wherein the object is built from an idea. Rather than having a subtractive process wherein an object is cut off, this one is built from scratch, layer by layer. While this technology is used by lots of experts and designers, hobbyists have started taking interest as well.
There are different kinds of 3D printing technologies, but the thing that they all have in common is the layering. The object is slowly being created layer by layer, forming the design you made. This uses what is referred to as the "additive processes� (more on this later). Your idea will be built from scratch, and while seeing it developed in your computer screen could already be amazing, having the product that you made yourself will definitely be something different, not to mention a hundred percent personalized.
After you come up with your design and you're ready to make it come to life, hundreds and maybe thousands of layers are slowly stacked on top of each other to produce the replica. This is the additive processes-where an object is made by way of successive layering of materials. Some of the most common materials used by 3D printing are plastics, metals like aluminum and titanium, glass, ceramics, and even food items like icing (many restaurants have already started using the 3D printing technology in order to create interesting designs for food like cakes and pastries).
To better understand it, think of it this way: this technology is the same with a regular inkjet printer in a way that layers of ink to create an image. With 3D printing, however, materials like plastic or wax are used instead of ink. This layer-by-layer building takes time, so don't expect to produce a finished products like how a regular printer produces 2D products.
3D Printing Technologies
There are many technologies that make 3D printing possible, and one of them is Selective Laser Sintering. This is where 3D printing and lasers come together; a technology that uses laser to fuse materials such as plastic, ceramics, or metal. Another technology is the Stereolithography, wherein a tank is filled with liquid photopolymer, which is sensitive to UV light, so the polymer solidifies when the photopolymer is touched by the laser. Another one is the Fused Deposition Modeling (developed by company Stratasys), which is a technology that makes a model come to life by heating and extruding material layer by layer.
What Makes 3d Printing Great?
One of the best things about this technology is that it has become very affordable. This was already around during the '90s, but back then, the prices were a lot higher than what we have now. Today, this is used by lots of businesses and companies that want to start out small. So far, this kind of ethnology is one the best ways to create and come up with 3D designs. It is now very convenient to have these amazing machines, because the parts that you need will already be provided-the materials will already be included, which means you don't needy to go through the long and tedious process of assembling all the pieces together. Today, you can find 3D printer kits for amateurs and hobbyists or advanced machines for businesses. This is the future of concept development; of manufacturing, and there sure will be more things to come out for us to explore soon.
