Machines under 2000 EUR are more and more interesting for home and educational use. This paper presents the development of a 3D printer that shapes the parts layer by layer by depositing the material on a predefined position. The development is presented from the engineering point of view. The construction steps, the control and the actuator solutions are presented. The ABS plastic was analysed for its material properties. The 3D printer evolved from a prototype to the pre-production phaseDodajalne tehnologije vstopajo na trg v vseh cenovnih segmentih, razvoj novih naprav in materialov pa je v konstantnem teku. Naprave s ceno pod 2000 EUR so vse bolj zanimive za uporabo doma in v izobraževalne namene. Članek prikazuje razvoj 3D-tiskalnika, ki izdela izdelek s ciljnim nalaganjem materiala na določena mesta posameznega sloja. Prikazan je inženirski pogled na razvoj. Predstavljeni so konstrukcijski koraki in rešitev vodenja. Analizirane so bile lastnosti materiala ABS. Izdelek je prešel prototipno fazo in je sedaj v predproizvodni faziTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
