What is a 3D printer?

    

• Do you know what is a 3D printer?  

A 3D printer is a machine that is quite quite different to the normal printer because a 3D printer can print out in Metal,Plastic, and it can be all over the world so when you listen carefully you might know some more  facts about 3D printing.

3D printer is unlike of the common printers. On a 3D printer the object is printed by three dimension. A 3D model is built up layer by layer. Therefore the whole process is called rapid prototyping, or 3D printing.

• Design.

With a 3D printer, we can create objects impossible to make a single piece by other means of production. It is possible to print objects within objects, hollow parts, interconnected parts, moving pieces, complex twist, and intricate details.

• Preparing for print.

It all starts with making a virtual design of the object you want to create.

This virtual in a CAD(Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object) or with the use of a 3D scanner (to copy an existing object).  A 3D scanner makes a 3D digital copy of an object.

• How to download on STL file.

The STL file format is widely used across different 3D printing and modeling interfaces. For instance, many of the models you might find on Thingiverse.com are available in STL format, and serval popular 3D printers accept STL files to prepare models for fabrication. This extension provides Import/export functionality for STL files to and from Sketchup, so you can easily export Sketchup groups to STL, or import an STL design and manipulate it within sketchup.

This is what it looks like.
