What is 3D printer?

3D printing is an innovative technology that allows you to create physical objects from a digital model. It began in the 1980s and its original name is "rapid prototyping".

Nowadays 3D printing technology has changed a lot and today 3D printers offer diverse functions allowing you to create everything you can imagine. 

The 3D printer are usually large machines that cost hundreds of thousands of dollars but technological advancement is making them available to the public. As the 3D printer can print everything, Come on, it's time to have a factory at home!

How does 3D printer work?

There are already many 3D printer brands in the market and 3D printing has been expected to have bright prospects. Why? 

That's wonderful, as you can get a real object that you designed on the computer via 3D printer. To get a 3D effect, it is necessary to use special computer programs and instructions to control the printing process. Even if you are not professional, it's very easy for you to use 3D printing program.

3D printing objects

In addition, 3D printer manufacturers have some of their own three-dimensional templates that you can download.

At the time of printing, we transmit the information of our design from the computer to the 3D printer via USB connection. The 3D printer works on layers successively until it manufactures the whole object completely (bottom-up).

3D printing process

There are more than one 3D printing filaments. They are usually sold in rolls, and all of them are thermoplastic materials. The important thing is that they are flexible and able to withstand the high temperatures that 3D printer requires.

A very efficient material is PLA (poly-lactic acid) a versatile polymer built with renewable resources. It's been used for a long time in the medical, packaging and textile industries. Get a quick 3D printing, it emits no harmful gases and is ideal for those who are starting to handle 3D printers.

The 3D printers have been widely used in many sectors, such as persoanl designs, transport, prostheses and even human organs, etc.

You may want to buy a 3D printer, but may be discouraged by its stiff price. However, GearBest will give what you want.

The materials used to print on a 3D printer are be different and it  depends on the printing objects and the price of 3D printing. The main materials are thermoplastic, and there are also other materials like nylon, metal, wood and others. On GearBest, you will find more 3D printing materials. 


The plastic is one of the most common printing materials, as they can be easily heated and molded. The main 3D filaments used for 3D printing  are PLA, ABS, HIPS, FilaFlex and others that contain additives such as wood or rubber.

3D printer filaments

The 3D filaments of ABS (acrylonitrile butadiene styrene) is suitable for printing some objects that require strong and resistant. ABS is the plastic with which they create pieces like Lego or the one found in some appliances.
