Surely you must have heard about magical printers that from nowhere "create" objects from a computer, just send it to print, as if sending a document to our printer in our home was. Basically that's 3D printers. In this post we will give you some basics to understand 3D printers.

What is a 3D printer?

A 3D printer is basically a machine capable of materializing figures with volume (width, length and height) from a design made by computer and sent to print from it. The result of a 3D printing is to produce a real 3D physical model. 3D printers are able to print and create complete objects.

How a 3D Printer Works

3D printers create an object with its 3 dimensions (width, length and height) through a layered process in which layers are successively constructed to get the object that was sent to print. The process used by these printers to create objects by layers is called "additive process", precisely by the action of adding those layers as we explained.

Types of 3D printers

There are basically two types:

 1- Polymer Addition or FDM Printers: This printer melts a filament of polymer wire through an outlet and depositing layer on layer of the molten material until creating the solid object. This way you can get parts using ABS plastic (similar to the material of Lego toys).

2 - Printers 3DPor laser: In this category are known two subtypes. SLA 3D or photosolidification printers that rely on hardening a polymer to light. The laser literally solidifies the base as it leaves the container to create the object that has been printed. Also in the area of ​​3D laser printers are the SLS printers, which means "laser sintering of a material". In these printers the material, unlike the SLA, is in a state of dust. The laser here impacts the powder by melting the material and solidifying it (sintered).

Most Used Materials

The materials most used in 3D printers are polymers or plastics, among which are ABS (acrylonitrate butadiene styrene), PLA (lactic acid), Laybrick, Laywoo-D3 and Filaflex.
