Ok. We are makers. We are the good guys. We are honest. So, now, raise your hand if you really don’t know what is the 3D printing. Yes, I see you don there!

Well, this post is for you, you’ll never miss the point anymore!

What is the 3D Printing? Our friends at 3D Hubs, huge makers and 3d-printers community, come in our help.

3D Printing is an additive manufacturing process that creates a physical object from a digital design. There are different 3D printing technologies and materials you can print with, but all are based on the same principle: a digital model is turned into a solid three-dimensional physical object by adding material layer by layer.

How does 3D printing work?

Every 3D print starts as a digital 3D design file – like a blueprint – for a physical object. Trying to print without a design file is like trying to print a document on a sheet of paper without a text file. This design file is sliced into thin layers which is then sent to the 3D printer.

From here on the printing process varies by technology, starting from desktop printers that melt a plastic material and lay it down onto a print platform to large industrial machines that use a laser to selectively melt metal powder at high temperatures. The printing can take hours to complete depending on the size, and the printed objects are often post-processed to reach the desired finish.

Available materials also vary by printer type, ranging from plastics to rubber, sandstone, metals and alloys – with more and more materials appearing on the market every year.
