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.
The maximum temperature at which the device can perform to the optimal level.

The printer will automatically build extra structures to support the item as it is printing. The extra support can then be easily removed.
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.
This feature saves time and effort in terms of maintenance, however the build platform itself still needs to be manually levelled.
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.
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.

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.
Similar to regular 2D printers, this type of 3D printer mixes different colors between cartridges. This process allows the printer to reproduce the color spectrum, therefore allowing you to print in almost any color.
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).
