Description

3D print system

Technical field

This utility model relates to a kind of 3D print system.

Background technology

3D prints and both need not paper using, it is not required that with black, but design a model as source with Computerized three-dimensional, by soft Part is layered discrete and numerical control molding system, utilizes the mode such as laser beam, hot melt nozzle by metal dust, ceramic powders, plastics, thin The special materials such as born of the same parents' tissue are successively piled up and are cohered, and final superposition molding produces entity products.Its advantage is to be greatly saved Production piece Production Time, and the product that moulding is complicated " can be printed ".

Existing 3D based on FDM (Fused Deposition Modeling technique Fused Deposition Modeling) technology prints system Based on unit, printhead or the two print head arrangement of constant spacing as unification, industrial 3D printer many uses SLA forming technique. Fusion sediment (FDM) is sometimes otherwise known as fuse deposition, and thread heat-fusible materials carries out heating and melting by it, by with Material extruded by the extruder of minute nozzle.Shower nozzle can move along X, Y, Z axis direction by workbench relatively, melted silk Material can be bonded together with preceding layer material after being extruded immediately.After layer of material deposition, shower nozzle is pressed pre-relative to workbench along Z axis Fixed increment rises a thickness, then repeats above step until the complete molding of workpiece.

The 3D printer of currently used FDM mostly is single head monochrome and prints, and along with the raising of printing precision, the time-write interval is several What level rises.3D colour print is typically by using special printhead and being equipped with special special consumptive material and realize, and equipment becomes This is higher.3D prints and mostly is mono-material printing, when object has multiple requirement to material, is typically all by by multiple unlike materials Object be mutually combined and meet, need to additionally design the combinative structure between each object, add redundant structure and operation, improve Design difficulty and cost.The 3D printer of single head, after consumptive material runs out of, it is necessary to break-off is to change consumptive material, and some prints Machine even can cause printing unsuccessfully because consumptive material is finished.Common 3D printer is of a great variety, and function is the most different, but all cannot Carry out function upgrading.One printer, the when of producing, its function determines constant the most substantially, at most carries out software The optimization of aspect.If user needs other functions, can only select to buy another printer, the printer before bought just may be used Idle article can have been become.

Therefore, there is inefficiency in existing 3D printer, it is impossible to uses while realizing multiple types color, material, Cannot be carried out the shortcoming that function upgrading production capacity expands, practicality has to be strengthened.
