Printers based on fused deposition modeling (FDM) use a thermoplastic filament, which is heated to its melting point and then extruded through a nozzle, layer by layer, to create the object. One of the main advantages of printers based on FDM is that they work with a wide range of materials.

A heated build platform helps keep the lowest levels of a print warm as the higher layers are printed. This allows the overall print to cool more evenly.
The 1.75mm filament diameter is gradually overtaking the previous 3mm standard. The 1.75mm filament feeds into the printer with greater ease and allows for more detail in the printing process.
The speed at which 3d objects are printed, measured in millimeters per second.
More extruder heads allow you to use different colors and different types of material at the same time. A second extruder is also required to build PVA/PLA support structures around items as they are printed.

The smaller the nozzle, the more detailed the final product can be. However, when speed of printing is of greater importance than detail, a larger nozzle may be preferable.
Polylactic acid (PLA) is popular in 3D printing as it cools and sets quickly. Unlike ABS plastic, it is biodegradable and therefore better for the environment. It can be used to build support structures for other printouts, as it can then be dissolved leaving no marks.
The printer prints in ABS (acrylonitrile butadiene styrene). This is up to 30 times stronger than regular plastic and is commonly used in 3D printing.
Polyvinyl Acetate is another form of plastic used in 3d printing similar to ABS. It can be used to build support structures for other prints, as it can then be dissolved leaving no marks.
A single design can be made up using different colored materials simultaneously.

The thinner each print layer is, the more detailed you can make your designs. Layer thickness is often also referred to as resolution and is measured in microns (µm).
