How Does a 3D Printer work

In the modern day and age of technology, anything and everything seems to be possible. What was considered to be a fantasy a few short years ago can now be converted in to physical realities. The world is moving forward at such a fast pace that it is actually difficult to keep up with it.

The latest news which is doing the rounds today is that of 3D printing. Even though this is something which would not make much sense to the masses, this is actually a pretty big deal for all the tech people out there. With the help of 3D printers, they will actually be able to make physical versions of their ideas in a way that’s affordable and accessible like never before. Based on that prototype or model, they will be able to decide if they would like to pursue the idea or not, or see whether any changes are required before heading into mass production. Also, if they do not like the idea, then they will be able to scrap it while it is still in the development stages. In this way, they would not have to bear the full-blown costs of developing and launching a product which won’t be any good.

If you want to know more about 3D printing and its uses, it would actually be a good idea to start with the basics first. In this case, it means getting to know just what 3D printing is.

3D printers

To explain it in very basic terms, 3D printers are machines which allow people to produce life-sized and three dimensional objects for computer aided design files. In addition, they are also very well-known for making everyday objects.

The best part about these kinds of printers are that they can make a wide variety of objects. In addition, these can be made with different materials and in different sizes. It’s amazing just how many things can be done with just one type of machine. Also, if reports are to be believed, 3d printers are also becoming a major hit in production lines. This is because 3D printers are replacing many different traditional machines since all the work can be done in one machine.

Why is it called “printing”?

A lot of people get confused by the name “3D printer”. But in reality, even though these devices make 3 dimensional objects, you will find a lot of similarities with the traditional printer. This is because in a traditional home printer, the ink is not staining the paper when it is coming fresh and hot out of the printer. It is actually sitting on the surface of the page. The same thing can be said in the case of a 3D printer as well. Many layers of plastic are built up, sitting one on top of the other. As the layers build up, it eventually leads to objects being made.

How 3D printers work

Now that you know about the basics, the last thing would be to know how these machines actually work compared to plastic injection molding machines. The first thing which you would have to do is design the 3D object. JCAD can help you with, along with printing your idea as well (use the form on the right hand side for a near instant quote). Once the design is ready, we simply push print and watch the magic unfold. Starting from tiny pieces, you will see the printer make the whole thing right in front of your eyes.
