What is 3D Printing and how it works

Nowadays technology is used in almost everything and in almost every industry we can think. It reduces time waste and process is much more efficient.

3D printer is also a one kind of technology revolutionizing the world. A 3D printer is a device which operates digitally and are controlled by digital files. It is used to manufacture 3D objects mechanically. It is also called as additive manufacturing because as we make object from it the objects do not build as it is rather it is build step by step, parts by parts.

Object is made layer by layer which is like stacking up cross sectional area to build up a whole object we want to manufacture. 3D printing helps you to make complex structures easily and without producing much waste and it also saves money and time which is very important in manufacturing industry.

How Does 3D Printing Work

The first step to use 3D printer is to have a 3D model. First, 3D model is made and it was verified as it is going to be made with the help of 3D printer. One can make their own 3D model or can also download it from 3D repository. There are many steps or methods to make 3D model by ourselves. When creating it yourself you can choose to use a 3D scanner, app, haptic device, code or 3D modeling software.

3D Modeling Software

You will find many different types of 3D modeling software tools available nearby. An industrial grade software can easily cost you a thousand a year per license, but there is also an open source software you can get for free.

We often recommend the beginners to start with Tinkercad. Tinkercad is a free application and it works in your browser fluently, you do not have to install it on your computer. Tinkercad offers beginner lessons and has a built-in feature to get your 3D model printed via a 3D print service. One can buy their best 3D model and can make it in real using their best 3D printer.

Now that you have a 3D model, the next step is to prepare the file for your 3D printer. This is called slicing.

Slicing: From 3D Model to 3D Printer

Slicing is an important process of any 3D printing process. It is a process in which we divide a 3D model into hundreds or thousands of horizontal layers and it is done with the help of a slicing software. To save time and hectic steps some 3D printer manufacturers manufacture their 3D printers which have a built-in slicer and let you feed the raw .stl, .obj or even CAD file.

When your file is sliced, it is now ready to be fed to your 3D printer. This can be done via USB, SD or internet. Your sliced 3D model is now ready to be 3D printed layer by layer.
That is how one can manufacture or make any object they want to make with the help of a 3D printer. To do this one must have knowledge about computers and should be able to handle applications smartly and efficiently.

3D Printing Industry

Adoption of 3D printing has reached critical mass as those who have yet to integrate additive manufacturing somewhere in their supply chain are now part of an ever-shrinking minority. Where 3D printing was only suitable for prototyping and one-off manufacturing in the early stages, it is now rapidly transforming into a production technology. Many industries are using this technology to manufacture their products with less labour and will also save their time which can be utilised to manufacture more products. Most of the current demand for 3D printing is industrial in nature. Acumen Research and Consulting forecasts the global 3D printing market to reach $41 billion by 2026. As it evolves, 3D printing technology is destined to transform almost every major industry and change the way we live, work, and play in the future.

Rapid Prototyping & Rapid Manufacturing

3D printing technology have revolutionized the manufacturing industry in no time. Companies have used 3D printers in their design process to create prototypes since the late seventies. Using 3D printers for these purposes is called rapid prototyping.

Why use 3D Printers for Rapid Prototyping?

We prefer 3D printers for rapid prototyping because it is much faster from general method and also cheaper. From idea, to 3D model to holding a prototype in your hands is a matter of days instead of weeks. Iterations are easier and cheaper to make and you don’t need expensive molds or tools.

After rapid prototyping, 3D printing is also used for rapid manufacturing. Rapid manufacturing is a new method of manufacturing where businesses use 3D printers for short run or small batch custom manufacturing.
