Additive Manufacturing – or 3D Printing
I suppose there is a great British tradition of men tinkering away in sheds at the bottom of gardens – inventing some amazing contraption or fixing that kitchen appliance that has decided to stop working.
I like to think that Additive Manufacturing - better known as 3D printing - falls into this same tradition. Its popularity, low cost and minimal barriers to entry have allowed a younger generation to rapidly realise ideas or quickly design and print spare parts for obsolete gadgets.
Printer Filament / 3D PrinterBefore I relate a little of my 3D printing story, I should explain how these amazing contraptions work. At the most basic level, these devices produce 3D parts by building up the part layer by layer. The media (and therefore the process of fusing the layers) can vary greatly. At the high-end, metal powders are used, which are then fused using a high-powered laser in a process called SLS (Selective Laser Sintering). The end result can be incredibly complex metal parts with shapes and hollow areas that would be impossible to create using traditional methods.
