Control method of 3D printer capable of being used for printing arcs

Abstract

The invention discloses a control method of a 3D printer capable of being used for printing arcs. The 3D printer comprises a rack and further comprises an outer driving gear, a lower gear ring and anupper gear ring. Upper driving teeth are arranged on the lower surface of the upper gear ring. Lower fixed teeth are arranged on the upper surface of the lower gear ring. A circumferential driving assembly is arranged between the upper gear ring and the lower gear ring and comprises an arc driving shaft. Two driven gears are arranged on the arc driving shaft. A horizontal moving shaft capable of moving left and right and extending in the front-back direction is arranged above the arc driving shaft. A lower connecting block is arranged on the arc driving shaft. An upper connecting block is arranged on the horizontal moving shaft. A printing head is arranged on the lower surface of the lower connecting block. The outer driving gear is rotated, accordingly, the upper gear ring is rotated, thus, the arc driving shaft can rotate around a fixed shaft, accordingly, the printing head is driven to make arc movement in a ring body of the upper gear ring, a lower driving gear can be used for adjusting the arc moving radius of the printing head, and an upper driving gear cooperates with the horizontal moving shaft so as to drive the printing head to make front-back and left-right movement. Thecontrol method provided by the invention is used for the 3D printer.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a method for controlling a 3D printer capable of printing arcs. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond materials, which create three-dimensional objects by printing layers of adhesive materials. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. [0003] Existing 3D printers often only have X-axis and Y-axis, which leads to the fact that the arcs printed by existing 3D printers are connected by multi-segme...

Problems solved by technology

[0003] Existing 3D printers often only have X-axis and Y-axis, which leads to the fact that the arcs printed by existing 3D printers are connected by multi-segment straight lines in the Cartesian coordinate system, so that the printed surface of the product will be It presents the phenomenon of splicing multiple planes, resulting in edges and corners
