Abstract

The invention provides a high-precision 3D (three-dimensional) printer which comprises a frame, transverse guide rails, longitudinal guide rails, a spray nozzle base and transverse and longitudinal driving mechanisms. The driving mechanisms comprise stepper motors and transmission belts; the spray nozzle base can slide along the transverse guide rails, and the transverse guide rails can slide along the longitudinal guide rails via transverse guide rail seats; the surfaces of the transverse guide rails are made of a resistance material, a transverse slide contact which is in contact with the surfaces of the transverse guide rails is arranged below the spray nozzle base, is serially connected with an ohmmeter and then is separately connected to two ends of each transverse guide rail, the ohmmeter is coupled with an arithmetic unit, and the arithmetic unit is coupled with stepper motor controllers; the surfaces of the longitudinal guide rails are made of resistance materials, and longitudinal slide contacts which are in contact with the surfaces of the longitudinal guide rails are arranged below the transverse guide rail seats and are electrically coupled with arithmetic units in a mode identical to that of the transverse slide contact; the arithmetic units of the longitudinal slide contacts are coupled with the stepper motor controllers. The high-precision 3D printer has the advantages that the problem of instability of belt transmission mechanisms can be solved by using the printer and the printing precision can be improved.

Description

technical field [0001] The invention relates to the field of electromechanical equipment, in particular, a 3D printer. Background technique [0002] At present, the development of 3D printers is rapid, and the most commonly used ones are hot-melt 3D printers; during the printing process, it is necessary to position the print nozzles to each position of the model section for printing; in order to realize the positioning of the print nozzles, the currently used The structural form is that the nozzle base is arranged on the transverse guide rail, and then the transverse guide rail seat of the transverse guide rail is arranged on the longitudinal guide rail; A longitudinal drive mechanism for sliding longitudinal guide rails, each drive mechanism includes a stepping motor and a transmission belt. Since the drive belt is made of rubber, it will be affected by ambient temperature, mechanical impact, and natural aging during use, making it difficult to stabilize its tension; Ma...
