Fused deposition type 3D printer disc type multi-head printing device

Abstract

The invention discloses a fused deposition type 3D printer disc type multi-head printing device, which comprises a wire guide tube rack (2), a wire guide tube (3), a wire feeding stepping motor (4), a wire changing stepping motor (5), a driving gear (9), at least two wire feeding modules (10), a driven fluted disc (11), a guiderail frame (13), at least two hot-melt runners (14), at least two heating blocks (15), a main shaft (17), at least two nozzles (18) and a substrate (19). According to the fused deposition type 3D printer disc type multi-head printing device, the automatic printing switching of various consumables under the driving of the two motors can be realized, one-time forming printing of various colors can be realized, the one-time forming of various material structures can be achieved, the automatic printing switching of various consumables can be realized, and the large-member and long-time unmanned printing can be met.

Description

technical field [0001] The invention relates to a disc-type multi-head printing device of a fused deposition type 3D printer. Background technique [0002] In the prior art, the 3D printer based on the fused deposition modeling method uses a filamentary printing consumable with a diameter of 1-2mm. The printing device of the printer is controlled by a computer to achieve layer-by-layer melting and superimposition, and the three-dimensional molding is gradually formed. There are many kinds, such as: red, yellow, blue, black, white, etc.; the raw materials used in consumables are also divided into many kinds, such as: ABS, PLA, PTA, etc., but the current fused deposition 3D printer printing device only has one or Two print heads, the forming color is simple, and the combination printing of multiple colors cannot be realized. The forming structure is simple, and the forming and printing of various structural consumables cannot be realized; the multi-consumables cannot be automa...
