23 facts in comparison
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 printer will automatically build extra structures to support the item as it is printing. The extra support can then be easily removed.
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.
A single design can be made up using different colored materials simultaneously.

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.
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 is able to print in High Impact Polystyrene (HIPS). HIPS is similar to ABS plastic, but uses different solvents (limonene rather than acetone). HIPS is easy to paint and glue.
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.
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).

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.
The device is set up and ready to be used with the included software.
As the product arrives fully assembled, you do not have to build it from a kit.
