Hey ! I’m back with another blog. And this time the topic is quite interesting. We all buy various home decors and toys from stores and it also proves to be pretty expensive. All of us frequently use printers but what if all the expensive decors and designer objects or toys could be printed. Well, yeah guys, I am talking about the amazing technology that has been a dream for many tech enthusiast including me, 3D Printing. Once considered to be fiction, now it is truth and is growing rapidly. So let’s know “What actually is, 3D Printing ?”. A single person can’t be given credit for this technology but various names have come forward with the advent of various methods of 3D printing. 3D printing was first introduced around in 1980’s with various patents. But Chuck Hull (founder of 3D systems) stood out by introducing the stereolithography method in 3D printing. Since then, approximately 7-8 methods of 3D printing have been invented. We will list each one of them later on in this blog.
3D Printing uses a 3D Model to print the object. A user can make 3D models using open source softwares such as Blender or Tinkercad. These softwares provide free tutorials on how to build 3D printing models. Once the 3D printing model is complete, the user can transfer the data into the 3D printer using USB, Wi-Fi etc. This is where the 3D printer stands out. The data that is sent to the printer is in 3 Dimension but the printer divides the model into multiple layers which transforms the 3D model into more of a repetitive 2D model. This eases the process for the printer. This whole process is called slicing. Following 7 methods are used in 3D printing :
- Vat Photopolymerisation
- Material Jetting
- Binder Jetting
- Material Extrusion
- Powder Bed Fusion
- Sheet Lamination
- Directed Energy Deposition
If I mention each method’s detail, it would seem to be a 10 page long document. But in a nutshell, all these methods use the concept of hardening of a material under room temperatures or under UV radiations though each technology has their own innovative twist. But amongst all these, generally 3D printers use Material Extrusion widely under the name Fused Deposition Melting (FDM).
There are many perks of using 3D printing in daily life as well as complex studies. Major feats can be achieved by using 3D printing. For instance, palaeontologists can recover old fossils and look into their features by creating the actual organism. An organisms body can be printed using only its skeletal structure and also in forensics, it can be used to rebuild a destroyed evidence. Whereas in daily life, we can use it for printing various home objects such as a vase, a container, a toy and there’s many more to it.
Isn’t this a cool and awesome technology. Do you want to own a 3D printer ? Well, who doesn’t, I also do. But, these printers are quite expensive and generally not affordable. But there are websites which are ready to print your designs and give you a less expensive way. But we can keep our fingers crossed because as soon as this tech takes the market by storm its prices are likely to fall down. And we will hope that day comes a bit sooner.. till then only those who are willing to give up their iPhone 7 to buy a 3D printer can afford it… (pun intended).
