3D printing is a process of manufacturing a three-dimensional products using a variety of materials. It is a technology to make anything quickly using a digital format respective products.
3D printing technology is the latest technology which is used for many purposes in todays
life. Here we are going to study how this technology works and what are the usage of 3D printing and including the features and functionality of using this technology?
- Advantages and disadvantages
What is 3D printing?
So, 3D printing is the latest technology that eases the work. 3D printing is actually making a proxy image or cloning the object with an easier method. 3D means three dimensions . We can see the depth of a 3D model. In 3D printing, you can print the model as it is the way it looks. This means if anybody wants to make a model of a house or any architecture we can use this technology.
Examples of 3D Printing
3D printing includes many sorts of technologies and materials as 3D printing is being adopted in almost all industries worldwide.
- Consumer products (eyewear, footwear, design, furniture)
- Industrial products (manufacturing tools, prototypes, functional end-use parts)
- Dental products
- Architectural scale models & maquettes
- Reconstructing fossils
- Replicating ancient artefacts
- Reconstructing evidence in forensic pathology
- Movie props
The invention of 3D printing was done by Charles Hull in 1980.Charles invented the first commercial way of prototyping technology. The fastest and cheapest way of making proxy or prototyping technology. As technologies are always getting updated and upgraded.
Functionality of 3D printing
The meaning of 3d printing is additive manufacturing .3D printers print the model in such a way that when we combine all the parts it will make a proxy image of the model. It works by the slicing or layering process.3D printer uses computer-aided design (CAD) to create a model. IT uses various types of material for printing like plastic, metal, resin, thermoplastics, fiber, and ceramic. We can make 3D printing technology in many industries like automobile industries,
Hospital industries and many more. Nowadays people are making weapons, houses, and toys by using this technology at a very low cost with very little manpower.
- World’s first 3D printed object was an eye wash cup.
- The USA remains the global leader in 3D printing with more than 35% market shares.
- In Asia about 50% of the market is covered by China followed by Japan at 30% and South Korea at 10%.
- Now technology is upgrade in such a manner that people are making houses, human organs, and building models from this technology.
- The process of 3D printing has to be done in very traditional way. There are very few limitations in traditional processes so it’s very flexible for 3D printing.
- 3D printing allows persons to complete task in very less time that affects the very low cost of production and work is done more efficiently as compared to other prototyping machines.
- The 3D designs files are stored on CAD or STL files to help in production. No need to store the inventory of stock. Editing designs can be also done in less time and fewer tools.
- The models made by 3D printing are lightweight and strong as they are made from plastic. It is light in weight and durable. Such kinds of parts or equipment are very useful in the automotive and aerospace industries.
- The main advantage of 3D printing is we can reuse and recycle waste in the process. So, there are very less chances of dumping waste.
- First disadvantage of 3D printing is it has limited material to be used in the process. Very less metal and plastic which can be used in the particular temperature for the process. In addition to this very less materials are recycled and food safe.
- Large size is another disadvantage of this technology. Due to the small size of the printing chamber can’t able to print large size models. If anyone wants to print then they have to split it and then print.
- Printing process of models is easy and faster but the post process is very slow as it needs waterjet ting, sanding, rinse, chemical soaking and air heat drying. So all this process is done after printing so it is much time consuming.
- As 3D printing is additive manufacturing it create model or part in layers or slices .This may cause in durability or strength of part or model.
