The invention discloses a kind of method that intensive treatment is carried out to 3D printing profiled member.3D printing profiled member is placed in the container of the thermosetting resin for filling liquid, then container is placed under vacuum condition is processed, it is cured after obtain a kind of 3D profiled members of reinforcing.3D printing profiled member after being processed by technical solution of the present invention, its internal structure forms DB, with resistance to compression, fracture resistance, and due to the surface tension of watery resin, original more coarse surface and microgroove are filled and led up, the overall mechanical properties of former profiled member are effectively increased.Profiled member can also carry out secondary operation, and realize 3D printing profiled member can practical application.The technical scheme equipment that the present invention is provided is simple, low production cost, cycle is short, efficiency high, with popularizing application prospect.
Description
Technical field
Structure-reinforced technology is carried out to profiled member the present invention relates to a kind of, more particularly to one kind is to using FDM(Melting is heavy
Product shaping)The method that the structure of the profiled member that desktop level 3D printing is obtained carries out intensive treatment.
Background technology
3D printing technique is a kind of quick molding method, and electromechanical industries are widely used in now, due to profiled member itself machine
The weakness of tool intensity, as just the primary aspect of design model, still should not be used to actually used.Using fused glass pellet
(FDM)Technique, PAL, ABS profiled part obtained by desktop level 3D printer processing, has bad mechanical strength, quality loose
Deficiency, therefore, its range of application is subject to more to place restrictions on.
In view of the Forming Theory of the profiled member of 3D printer fusion sediment at present, surface texturisation is comparatively dense, but inside into
Alveolate texture, causes profiled member bad mechanical strength, is easily broken off, bends, deforms, and its practical application has certain limitation
Property, it is limited by very large more multi-field.
In order to improve the mechanical performance of profiled member, prior art is reinforced in the several mode of 3D printing part, including one
Only surface of shaped parts is reinforced a bit, the mechanical structure inside structural member is not improved.Although can be using encryption pad
Method, but curring time is very long, influences the process-cycle;Such as select 100% filling(Fill)Mode, this 3D printing method
Curring time can be caused very long, the process time of 100% filling is 4~5 times of 20% filling.In addition, when the filling for being higher than 75%
Rate is likely to influence profiled member outer surface, brings the size distortion of profiled member.Reinforcement technique is additionally included in design profiled member
The cast aperture of Shi Liuyou epoxy resin, rear injection epoxy resin to be formed, but this reinforcement means do not have really to be improved into
Structure inside type part.
Prior art either adds hole to fill, or surface coating, the internal structure of former profiled member is not improved, only
A resin " vest " is put on to plastics printout, the mechanical performance such as not yet real resistance to compression, anti-folding for improving profiled member structure.
There is provided it is a kind of effective reinforcing and processing method is carried out to 3D printing part, with ensure parts density strengthen, make 3D into
Type part is difficult to break, and can on demand bear bigger mechanical pressure, is beneficial to further expand the application of 3D forming techniques
Scope.
The content of the invention
The compactness that the present invention exists for the profiled member that the level 3D printer processing of existing fused glass pellet desktop is obtained
A kind of difference, the low deficiency of structural strength, there is provided low production cost, cycle is short can effectively improve 3D printing profiled member structural strength
Method.
Realize that the technical scheme of the object of the invention is to provide a kind of method that intensive treatment is carried out to 3D printing profiled member, will
3D printing profiled member is placed in the container of the thermosetting resin for filling liquid, then container is put into vacuum tank, is evacuated to true
Carried out at solidification after reciprocal of duty cycle is -2KPa~-10Kpa, and container is taken out after being kept for 10~15 minutes, then the profiled member that will be obtained is filtered dry
Reason, obtains a kind of 3D printing profiled member of reinforcing.
3D printing profiled member of the present invention is, using fused glass pellet technique, to be processed by desktop level 3D printer
Arrive.
The solidification temperature of the thermosetting resin is in the range of 60~140 DEG C.One preferred scheme is thermosetting resin
Using epoxy resin/imidazole system, the epoxy resin and curing agent imidazoles are liquid at normal temperatures.
Principle of the invention is:The profiled member of former 20% filling rate is placed in vacuum environment, the resin of liquid permeates completely
To 3D profiled members, then solidified using Low Temperature Thermal or microwave curing;After curing time, terminates, the machinery inside former profiled member
Structure forms DB, resistance to compression, anti-folding, and surface is again due to the surface tension of watery resin so that original more rough surface,
Microgroove is filled and led up.
Compared with prior art, the beneficial effects of the present invention are:Using vacuum pumping technology, the sky in profiled member is excluded
Gas, enables the thermosetting resin of the liquid with reinforcement effect to penetrate into inside 3D printing profiled member, and one is formed with raw material;
Curing process is used again, the thermosetting resin of infiltration profiled member is become solid-state by liquid completely, effectively increase former profiled member
Overall mechanical properties;Profiled member can also carry out secondary operation, and realize 3D printing profiled member can practical application.The present invention is carried
The technical scheme equipment of confession is simple, low production cost, cycle is short, efficiency high, with popularizing application prospect.

Specific embodiment
Technical solution of the present invention is further elaborated with reference to the accompanying drawings and examples.
Embodiment 1
Using fused glass pellet(FDM)Technique, the PAL profiled members obtained by desktop level 3D printer processing, to the 3D for obtaining
Printing shaping part carries out the enhanced treatment of structural strength.
Referring to accompanying drawing 1, it is that the operation principle that intensive treatment is carried out to 3D printing profiled member that the present embodiment is provided is illustrated
Figure;3D printing profiled member 1 is put into the container 3 of the thermosetting resin 2 for filling liquid, the solidification temperature of thermosetting resin exists
In the range of 60~140 DEG C, epoxy resin/imidazole system is such as selected, epoxy resin and curing agent imidazoles used is equal at normal temperatures
It is liquid.Printing shaping part 1 is totally submerged in the thermosetting resin 2 of liquid, then container 3 is put into vacuum tank 4, extracts tank
In air to -0.3 atmospheric pressure, taken out after being kept for 15 minutes;Profiled member is taken out from container, is placed in heater box after being filtered dry,
Curing process is carried out by the curing process of the thermosetting resin for being used, after natural cooling, the 3D printing profiled member reinforced.
