This is an interesting project that shows the potential of Rapid Prototyping using SLS and metal. SLS is a 3D printing process based on sintering. A CO2 laser is used to sinter a thin layer of heat-fusible titanium powder that gradually builds up the 3D model. These...

There are many different ways to 3D print an object. But nearly all of them utilize computer aided design (CAD) files. CAD files must be translated into a “language,” or file type, that 3D printing machines can understand. Standard Tessellation Language...

In a typical FDM system, the extrusion nozzle moves over the build platform horizontally and vertically, “drawing” a cross section of an object onto the platform. This thin layer of plastic cools and hardens, immediately binding to the layer beneath it....

FDM is the most common type of rapid prototyping due to it’s low cost. This is the type that you will be familiar with in school. FDM printers use a thermoplastic filament, which is heated to its melting point and then extruded, layer by layer, to create a three...
