What is 3D Printing? Where it is Applied?

3D printing or manufacturing is the process of producing solid three-dimensional objects from digital data.

Create a 3D printed model using the additive process

In an additive phase, one object is formed by the creation of subsequent objects. Each layer is ultimately a thinly cut horizontal diagonal of the object.

It is about minimizing production, cutting/hollowing metal or plastic pieces like a grinding machine.

Also, allows you to create complex shapes using less material than conventional production methods.

How does 3D printing work?

Starting with the 3D model. You create or import it from a 3D server. Build it yourself using 3D scanner, computer, haptic tool, code or 3D modelling software.

3D Modeling Software

There are many 3D modeling software available. Licensing industry-standard software costs thousands of dollars per year, but you can also get free opensource software.

We also recommend beginners to Tinkergate. Tinkergate is free and you don’t need to install it on your computer. Tinkergate provides beginner lessons and a built-in feature to print your 3D model through a 3D printing service.

Now with a 3D model, the next step is to make your 3D printer file. This is called Slicing.


3D printer slicing from a 3D model divides a 3D model into hundreds or thousands of horizontal layers, using slicing tools.

Most 3D printers have a built-in slicer and even provide raw.stl, .obj or CAD files.

Once your file is cut, it will be delivered to your 3D printer. This can be done via USB, SD or the Internet. Your cut 3D model is ready for layer-by-layer 3D printing.


The industry has embraced 3D printing as it has reached a critical mass, as more and more people who are not affiliated with their supply chain are now part of the ever-shrinking minority. In the early stages, it was only suitable for prototype and one-off production, and now it is rapidly evolving into industrial technology.

Market Size

Most of today’s 3D printing market is commercial. Acumen Research and Consulting expects the global 3D printing market to reach $ 41 billion by 2026.

As it progresses, 3D printing technology is expected to disrupt every major industry and change how we live, work and play in the future.

The definitions of 3D printing involve many types of technology and materials, as 3D printing is used in almost all industries you can think of. It is important to look at this as a cluster of different industries with multiple applications.
