FIELD: manufacturing technology.
SUBSTANCE: invention relates to design of 3D printers operating in FDM-technology and can be used for layer-by-layer formation of articles based on their three-dimensional digital representation. Traveling element has length exceeding both length of guide element and length of table travel by value which is not less than length of guide element; the end sides of the guide element are arranged on both sides relative to the vertical plane, in which during the reciprocal movement of the printing head the axis of its nozzle lies; guide element is arranged parallel and at a finite distance relative to vertical plane of symmetry of tabletop, which is orthogonal to its lateral sides located perpendicular to said horizontal guide and parallel to vertical plane, in which vertical guide axes lie.
EFFECT: avoiding the possibility of table vibrations caused by play as a result of wear of running and guide elements of the pair.
