Abstract
The utility model relates to a kind of 3D printer nozzle arrangements, solve 3D printing nozzle in the prior art, in discharge outlet, when being contracted to small-bore by heavy caliber, it is easy discharging have some setbacks, material stacking, plug nozzle problem.It include tapered feed inlet and cylindrical discharge port, the osculum end of tapered feed inlet is arranged with the direct intersection of discharge port by bull nose transition.It is more smooth to discharge, reduce the reflux of material, maintain the high fluidity of material, keep precision higher, while smaller thrust push can be used, reduces the loss of nozzle.
Description
Technical field
The utility model relates to a kind of printers to set components more particularly to a kind of 3D printer nozzle arrangements.
Background technique
3D printer is a kind of cumulative manufacturing technology, i.e. a kind of machine of rapid prototyping technology, it is a kind of mathematical model
Based on file, with adhesive materials such as special wax material, powdery metal or plastics, by printing jointing material from level to level
To manufacture three-dimensional object.Three-dimensional printer is used to manufacture product at this stage.The mode successively printed constructs the skill of object
Art.The principle of 3D printer is that data and raw material are put into 3D printer, and machine can produce from level to level product according to program
Come.
3D printer and the maximum difference of conventional printer are that " ink " that it is used is raw material true, heap
The form of folded thin layer can be used for the medium wide variety printed, from numerous plastics to metal, ceramics and rubber there are many multiplicity
Gelatin substance.Some printers can also enable that one, object printed is hard and other end is soft in conjunction with different medium.
Some 3D printers use the mode of " ink-jet ": using printer head by one layer of very thin liquid plastic substance
It is sprayed on mold pallet, then this coating is placed under ultraviolet light and is handled；Mold pallet declines minimum distance later,
Come so that next layer heap is stacked on.
Some is called the technology of " fused deposition modeling " using one kind, and whole flow process is that plastics are melted in spray head, is then passed through
The mode of depositing plastic material fiber just forms thin layer.Some is called the technology of " laser sintered " using one kind, using powder particle as
Print media.Powder particle is sprayed on mold pallet one layer of very thin powder bed of formation, founding at designated shape, then by
The fluid binder of ejection is solidified.
Some is then using the electron stream fusing powder particle in vacuum, includes complexity as hole and cantilever when encountering
Need to be added gelling agent or other substances when structure, in medium just to provide support or for taking up space.This amount of powder is not
Can be by founding, it is last that only need to fall supporter with water or gas washout can form hole.
Existing 3D printing nozzle, in discharge outlet, when being contracted to small-bore by heavy caliber, it is easy discharging have some setbacks,
Material stacking, plug nozzle.
Utility model content
Utility model aims to solve 3D printer nozzles in the prior art, in discharge outlet, by heavy caliber
When being contracted to small-bore, it is easy discharging have some setbacks, material stacking, plug nozzle problem.
To solve the technical solution that the technical issues of the utility model is proposed uses are as follows: the 3D printer of the utility model
Nozzle arrangements include the discharge port of tapered feed inlet and cylinder, the osculum end of the tapered feed inlet and discharge port
Direct intersection is arranged by bull nose transition.
Through the above technical solutions, the utility model has the following beneficial effects: the 3D printer nozzle arrangements of the utility model
The osculum end of tapered feed inlet be arranged with the direct intersection of discharge port by bull nose transition, so that discharging is more smooth, subtract
The reflux for having lacked material, maintains the high fluidity of material, keeps precision higher, while smaller thrust push can be used, and reduces
The loss of nozzle.
Detailed description of the invention
Fig. 1 is background technique 3D printer nozzle arrangements schematic diagram.
Fig. 2 is a kind of structural schematic diagram of 3D printer nozzle arrangements of the utility model.
Specific embodiment
It is described further below in conjunction with structure of the attached drawing to the utility model.
Referring to Figures 1 and 2, a kind of 3D printer nozzle arrangements include tapered feed inlet 1 and cylindrical discharge port
2, the osculum end of tapered feed inlet and the direct intersection of discharge port are arranged by 3 transition of bull nose.It is more smooth to discharge, subtract
The reflux for having lacked material, maintains the high fluidity of material, keeps precision higher, while smaller thrust push can be used, and reduces
The loss of nozzle.
Although being described in detail in conjunction with attached drawing to specific embodiment of the present utility model, should not be construed as pair
The restriction of the protection scope of the utility model.In range described by claims, those skilled in the art are without creation
Property the various modifications that can make of labour and deformation still fall within the protection scope of the utility model.
Claims (1)
1. a kind of 3D printer nozzle arrangements include tapered feed inlet and cylindrical discharge port, it is characterised in that: described
The osculum end of tapered feed inlet be arranged with the direct intersection of discharge port by bull nose transition.
