Problems solved by technology

Due to the fact that the extruder assembly and the print head move together in this installation method, the print head has a large mass and a large inertia during printing, which is easy to make the printing inaccurate, and the rigidity of the guide rail is also relatively high when the near-end wire feeding is used.

Embodiment Construction

[0013] [Multi-nozzle FDM-3D printer with belt-idler drive] Features:

[0014] The printer includes: a plurality of (2-100) extruder assemblies, a mechanical device or a gear / rack that carries the extruder assembly for 2-dimensional horizontal X, Y-axis movement with a belt-idler drive structure or Screw / sim transmission mechanism (the mechanical device includes: X-direction and Y-direction track mechanism), printing platform and lifting mechanism, electric control system, control panel and structural shell. The arrangement of the multi-extruder assembly system is divided into : Single X arrangement splicing method and multi-row Y arrangement splicing method.

[0015] Single X arrangement splicing method:

[0016] Multiple extruder assemblies carry their own extrusion nozzles, driven by their respective X drive motors, reciprocating along the guide rails; It reciprocates along the X direction under traction; the role of the belt idler is to increase the contact number of the ...

Abstract

A multi-sprayer FDM-3D printer with belt-idler drive is composed of 2-100 extruder assemblies, a belt-idler drive constructed mechanical device or gear / rack or lead screw / nut conveying mechanism carrying the extruder assemblies to move in the two-dimension horizontal X-axis direction and Y-axis direction, a printing platform, a lifting mechanism, an electric control system, an operation panel anda structure shell. The arrangement of a multi-extruder assembly system is divided into the single X arrangement splicing manner and the multi-row Y arrangement splicing manner. The extruder assemblies are used for pavement of one part of a section of a component slice and jointly finish pavement of the whole section of the product component slice. After one layer of section is formed, a workbenchrelatively descends by a certain height, pavement of the next layer is conducted, finally, a three-dimensional product component is formed, and the forming speed is greatly improved.

Description

[technical field] [0001] The present invention belongs to the technical field of machinery; to be precise, it utilizes multiple independent extrusion heads to operate independently in one plane, independently complete the respective plane areas, and complete the FDM-3D printing and forming method and its method by splicing. Extruder assembly. [Background technique] [0002] Fused Deposition Modeling (FDM) rapid prototyping process is a method of heating and melting various filaments (such as engineering plastics ABS, polycarbonate PC, etc.) and then stacking them layer by layer, referred to as FDM. There are many molding materials that can be used in most FDM rapid prototyping technologies, such as modified paraffin, (acrylonitrile / butadiene / styrene) copolymer (ABS), nylon, rubber and other thermoplastic materials, as well as multi-phase hybrid materials, Such as the mixture of metal powder, ceramic powder, short fiber, etc. and thermoplastic materials. Among them, PLA (po...
