3D Printing





Introduction
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. Additive manufacturing           refers to a process by which digital 3d design data is used to build up a component in layers by adding materials. The term “3D printing” is increasingly used nowadays as a synonym of additive manufacturing. 3D printing is the opposite of subtractive manufacturing which is cutting out a piece of metal or plastic with for example a milling machine.






History

Chuck Hull invented the first 3D printing process called ‘stereolithography’ in 1983. In a patent, he defined stereolithography as ‘a method and apparatus for making solid objects by successively “printing” thin layers of the ultraviolet curable material one on top of the other’.

How Does 3D Printing Work?


 

 
  • ·         It all starts with the creation of a 3D model in your computer. This digital design is for instance a CAD (Computer Aided Design) file. A 3D model is either created from the ground up with 3D modelling software or based on data generated with a 3D scanner. With a 3D scanner we are able to create a digital copy of an object. Otherwise if new product is to be designed, it can be created on 3d modeling software like AutoCAD, Creo, Inventor, etc. For 3d printing, the file must be saved in the format “.stl” which refers to stereolithography file.
  • ·         This STL file is then uploaded to a special purpose software provided with the 3d printer, also known as slicing software provided with the 3d printer, also known as slicing software. The software slices the object into number of layers. It also generates the tool path for the printing head. The output of the slicing software is CNC file which contains the manufacturing data.
  • ·         The CNC file is then uploaded into the printer which “prints” the object layer by layer.
