3D Printing An Amazing Additive Manufacturing Technology

Have you ever thought of producing your unique abstract imagination into a tangible object? Yes, you can produce it using 3D printing technology. Certainly, 3D printing is a kind of additive manufacturing process wherein a 3D solid object can be created using any kind of digital designing file.

However, the 3D printed object can be achieved by a unique printing process. Wherein an object is created by laying down successive layers of filament until the object is created.

This process can be used to produce any kind of complex shapes and design using fewer materials than that of conventional manufacturing technologies! Therefore it is being widely used in manufacturing industries, aviation industries, the Architectural sector, rapid prototyping, automotive sector, construction sector, and recently it’s being used even in the medical sector.

In simple terms you can just say that anything which you imagine, however complex your imagination maybe can be designed and printed in a 3 dimensional way so that you can touch and feel your imagination

How Does A 3D Printer Work

Firstly, it all starts with 3D modelling. These 3D modelling can be done using any modelling software such as Catia, NX, Creo, SolidWorks, SketchUp etc. Or if you do not know modelling u can still get the design files! From many reputed websites such as Thingsverse or any other by searching on google. Once you get your design file ready convert your file into STL file. As many slicing software’s can process your file when it’s in STL format. Now once your design file is ready in STL format you need to process them using the slicing software.

For instance, there are many slicing software available in the market. Industrial-grade software can cost you thousands of Rupees per year as license fees. And there are many free software’s also available in the market such as Cura from Ultimaker, ThinkerCad, etc. However, we always recommend beginners to use free slicing tools.

Now once you have your model design in STL format and slicing software. The next process you have to follow is to slice your design in the slicing software

Slicing The 3D Model:

To clarify, as the name itself suggest Slicing is the process where a 3D model designed is cut into the small horizontal or vertical layer to process the design easily. So to make the machine understand your design slicing process needs to be carried out. Secondly, the G-code created is copied in the USB and the data is provided to the printer.

Materials Used In 3D Printing:

A variety of materials can be used in the 3d printer based on the requirement. These materials are available in the form of a wire feedstock often called filaments. For example, some of the filaments available are PLA, ABS, TPU, WOOD, PLASTIC, CONCRETE, POLYMERS, SLA, PET-G, HIPS, etc. Certainly, the most commonly used and the relatively cheaper filament is PLA. Which is widely used in printing mechanical and architectural parts. It’s very important to know the characteristics and the uses of each of these materials before using them. So we will look into each of these materials in detail in our next blog on materials used in 3D printing

Applications Of 3D Printing :

As said earlier 3D printing technologies have a wide range of applications. As this process is the latest and trending procedure used in additive manufacturing. Further, let’s discuss one by one in which all sectors this technology is used. For what purpose they are making use of this technology. This may help users to know how we can make use of these kinds of new technologies.

Automotive :

Automobile manufacturers are using this technology for a long time, these companies are printing their spare parts, jigs, fixtures, and other mechanical parts.

Any car industry before manufacturing a car they go for the prototyping of a small scale. And then go for the 1:1 prototyping. So the small scale prototyping is done using this technology this helps the manufacturers to understand their design in a better perspective and they can rectify it if any changes are required.

Healthcare :

The Healthcare industry also has a huge application of this additive manufacturing technology. A lot of research work is being carried out in this field mainly called bio-printing. Above all, this technology is mainly used for hip replacements by orthopedician’s. Research is being carried out even on heart transplantation.

One of the field where this amazing technology is widely used is in dental field here they manufacture the molds using both resin and powder based processes.

3D Printing Technologies :

However, there are different ways to 3D print an object, mainly all these processes differ from each other in the way the layers are built to create an object. But, some methods use softening materials to extrude and some other use photo-reactive resin with UV rays layer by layer

Some of the notable 3D printing technologies are VAT POLYMERIZATION, STEREO-LITHOGRAPHY, DIGITAL LIGHT PROCESSING, CONTINUOUS LIQUID INTERFACE PROCESSING, MATERIAL JETTING, BINDER JETTING, FUSED DEPOSITION MODELLING, FUSED FILAMENT FABRICATION, POWDER BED FUSION, SHEET LAMINATION, DIRECTED ENERGY DEPOSITION all these processes will be discussed in detail in the upcoming blogs.

Cost Of 3D Printer :

Cost of a 3D printer varies based on the size of the bed of a printer, which company printer your purchasing if you opt to buy Prusa 3D printers you may find it costly whereas if you opt for Chinese companies such as Crealty you may get it a better price. Certainly, based on all these factors 3D printers range from Rs. 9,000 to Rs.10,00,000.

However, the size of the printer may vary depending on your need and the purpose of its use. Moreover, you may purchase a printer for your personal and research work or you may use it for commercial use depending upon which you can choose the size of the printer bed.
