Printrbot GO v2
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 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.
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.
The speed at which 3d objects are printed, measured in millimeters per second.
This feature saves time and effort in terms of maintenance, however the build platform itself still needs to be manually levelled.
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 device can connect to WiFi.
The device has a standard memory slot (such as an SD or micro SD card slot) so that you can either extend the internal storage with affordable memory modules or you can retrieve data, such as photographs, easily from a memory card.
With more USB ports, you are able to connect more devices.
