This technology has been invented in the late 80s and it was firstly available only for bigger companies: the machines were big and very expensive. Today, thanks to the RepRap Project [link] and to the expiration of the patent, it is quite easy to find affordable 3D printers like the FABtotum. Not many of them, anyway, are supported by a company but are more likely to be makers’ projects.
Here are the main reasons to prefer this solution:
- prices are generally lower for both the machine and materials;
- FFF can be quite quicker;
- sizes are bigger;
- materials range is wider (PLA, ABS, Nylon are the most common, see “Materials”).
FFF 3D printers are mainly divided in two other categories: >XYZ Cartesian 3D printers and Delta 3D printers. The first kind has three axis: a carriage moves on the X and Y and a square bed moves up and down on the Z, just like on the FABtotum. It allows to have a greater surface and it is of easier administration for the user. Delta 3D printers have an hexagonal or round bed and three arms that hold the extruder: in these products there are no fixed axis but all the movements are made by the arms.
