Today we all know that there are many products made with technology. Maybe we don’t even look surprised at these products. But no matter how much we have seen, we still have a few products in mind, and one of them is undoubtedly “3D printers”. If not, we can imagine that you will be surprised after reading this article.
Now we know more or less what 3D printers work. But we don’t know exactly what these printers do. How do these machines produce three-dimensional objects in a matter of hours? In this article, we will explain how 3D printers work and what they do. Now, without further ado, let’s examine this magic machine together.
What is 3D Printer?
Additive manufacturing, also known as additive manufacturing, is a device that produces computer-designed or 3D models quickly using various materials, without the need for an extra mold or fixture.
The most important purpose of 3D printers is undoubtedly cost. Particularly important for mechanical engineers, 3D printers make it indispensable for us to be able to produce parts cost-effectively even in small volumes of single batches.
How 3D Printers Work
The logic of 3D printers is based on the direct production of any three-dimensional model by melting plastic with layering technology.
For a better understanding of the working logic of 3D printers, we can subdue them:
- Modeling: As mentioned above, the first product of the product to be produced is computer data generated by 3D design programs (CAD) or 3D scanning systems. The created model is usually converted to STL file format and we take the first step of 3D printing process.
- 3D Printing: The most amazing part is the 3D printing process. The model that we send to 3D printing is created by laying the object on top of each other in layers during the printing process. These layers are made by different methods such as plastic melting, latin sintering and sterolithography.
- Surface Improvement: The objects we finally create with the 3D printer may contain dimensional errors compared to traditional technologies. In this case, a final surface cleaning, improvement or improvement finalization can be applied to critical objects.
Many technologies can be used in 3D printers. Differences between technologies are often related to how layers are formed. To list some of these technologies; SLS (Selective Laser Sintering), FDM (Fused Deposition Model), Stereolithography are among the most used technologies.
In terms of having this amazing technology, you can create 3D materials in your home with a budget of $ 2000 to $ 10000 as well as $ 1 million 3D printers.
