The novel 3D printing mechanism mainly aims at overcoming defects in the prior art, the layering phenomenon of printing can be effectively avoided, the surfaces of the printed objects can be even and smooth, and the appearances of the printed objects can be attractive.
Description
Technical field
The invention belongs to 3D printer field, specifically, relate to a kind of printing mechanism of 3D printer and there is the 3D printer of this printing mechanism.
Background technology
Rapid shaping technique can be used in the forming process that three-dimensional (3D) prints, and is realized the manufacture of three-dimensional body by the transfer process of computer data.Usually, 3D prints rapid shaping technique and mainly comprises three types: stereo carving (Stereolithography), successively superpose manufacture (LaminatedObjectManufacturing) and selective deposition moulding (SelectiveDepositionModeling).
The moulding general principle of selective deposition is data message three-dimensional body step section being obtained every one deck cross section, is created by object based on these information.The selective deposition of existing one is moulding is fused glass pellet (FusedDepositionModeling, FDM).The equipment of fused glass pellet includes an extrusion head, the feed arrangement of a silk material can be set in extrusion head, by heating element heater to after extrusion head heating, extrusion head can squeeze out the fluent material of melting, and the material squeezed out forms solid structure after cooled and solidified.
Because forming process adopts layering integrating method, the printing shaping time is general all very long.Connecting between layers of printable layer is only cohere rear cooling by the material of molten, and because material temperature is between layers different, the object strength therefore printed is lower.And after placing a period of time, the phenomenon of separating between layers can be there is.
Summary of the invention
Main purpose of the present invention is the defect for prior art, provides a kind of novel 3D printing mechanism and 3D printer.
Novel 3D printing mechanism provided by the invention comprises, comprise: print platform, extruder head assembly, extruder head assembly is arranged on above print platform, extruder head assembly comprises printing nozzle and is arranged on the first heater above printing nozzle, the below of first heater is provided with secondary heating mechanism, and secondary heating mechanism is for providing heat to the printing objects on print platform.
The beneficial effect of the technical program is: by secondary heating mechanism, effectively can avoid the lamination occurred in print procedure, the body surface that prints can also be made uniform and smooth, appearance looks elegant.
Further, secondary heating mechanism and first heater are all connected to a heater block.
Take technique scheme, required manufacturing cost reduces.
Further, first heater and secondary heating mechanism are connected to two independently on heater block respectively.
Take technique scheme, the temperature of secondary heating mechanism can better control.
Further, the described heater block that secondary heating mechanism connects has controller, and controller controls the temperature of secondary heating mechanism according to the instruction that outside inputs.
Further, secondary heating mechanism is connected with first heater by adjustable apparatus.
Further, adjustable apparatus is screw.
Further, secondary heating mechanism is between first heater and printing nozzle.
Take technique scheme, secondary heating mechanism can carry out temperature adjustment according to print platform, printed material and surrounding environment, and can adjust according to the regional extent of printing objects.
Further, the present invention also provides a kind of 3D printer, 3D printer comprises: print platform and track, track sliding is dynamically connected an extruder head assembly, extruder head assembly is arranged on above print platform, extruder head assembly comprises printing nozzle and is arranged on the first heater above printing nozzle, and the below of first heater is provided with secondary heating mechanism, and secondary heating mechanism is for providing heat to the printing objects on described print platform.
