The spatial FDM Technology printing enables illustrating a great number of technical issues by creating a model of the analyzed object e.g. directly, during didactic classes. A three-dimensional printer may be used in any field of knowledge, from biology, where the printer can be employed for printing the models of organs (printing of the organs themselves is also possible following the modification of the printer - when printing with TAULMAN Nylon filament, we can print e.g. the elements of bones or cartilages which may be implanted into a living organism) to printing spare parts and prototype elements for equipment, in architecture for printing complex scale models etc. The printer itself is a fantastic device, interesting for many fields of study. The 3D printer will enable students to learn how to program the processors based on ATMega, may prepare new software controlling the printer, design 3D graphics on computers, edit “scans” and files downloaded from the Internet, use the CAD software in practice and print the results acquired on the sets of printers. Moreover, each printer may be freely modified according to our own needs - from the change or transfer of the drive to replaceable extruders - the mechanisms forcing materials. The printer may also be changed into a laser plotter or even a milling machine following a slight modification of the extruder’s carriage or changing force belts into ball screws [1-4].
