Technical field
The invention belongs to intelligent Manufacturing Technology field, more particularly to a kind of processing that 3D printing metalwork is separated with substrate
Method.
Background technology
Metal parts 3D printing technique, as forward position and most potential technology the most in whole 3D printing system, is advanced
The important development direction of manufacturing technology.With the demand of development in science and technology and popularization and application, metal is directly manufactured using rapid shaping
Function part becomes the main developing direction of rapid shaping.Metal 3D printing is pyramidal top positioned at 3D printing, is considered as
It is threshold highest, increases the most fast and most technology of future, from aircraft engine part to medical implantation, automobile component, aviation
The manufacture of satellite component etc., has invariably shifted it onto the position of forefront.GE and Air Passenger these industrial aviation major parts are even more by this
A unprecedented height has been lifted in the application of the technology of kind.
The general principle of metal 3D printing is：First, being separated into continuous three-dimensional CAD digital-to-analogue using microtomy is had
The hierarchy slicing of certain thickness and order；Second, extract each layer of produced profile of section and designed according to slicing profile and closed
Laser scans path, laser scanning speed, laser intensity of reason etc., and it is converted into corresponding computer numerical control (CNC) program；
3rd, laser melting deposition chamber is vacuumized, and the inert protective gas of certain pressure is filled with, prevent when powder from melting by oxygen
Change；4th, computer control liftable system rises, and powder is pushed to forming parts room work by powder muller from powder storage chamber
Make the substrate on platform, while laser is under computer instruction control, is scanned, dissolves according to the scanning imaging system pre-set
Paving is sprinkled upon the powder on substrate, cladding generation and this layer of cladding layer consistent in shape and size；Finally, powder storage chamber is moved up
And forming parts room moves down a slice thickness and repeats said process, successively cladding accumulation is until forming designed by CAD model
Part.After printing is finished, printed object is separated by the mach mode such as milling or wire cutting from substrate
Get off.
At present, metal 3D printing always needs post-processing.Because at least, it is necessary to by being machined the gold printing
Category part is lifted down from metal substrate, and so, the metal parts of printing needs following process, and the substrate originally adhered to is also needed
Process, or even scrap, waste time and energy, waste of resource.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of processing method that 3D printing metalwork is separated with substrate,
By spraying boron nitride coating in substrate surface, realize that the object of metal 3D printing is quickly separated with substrate, solve 3D printing
Metal parts needs following process, the substrate originally adhered to is also required to processing, or even scraps, and wastes time and energy, and waste of resource is asked
Topic.
The technical solution adopted for the present invention to solve the technical problems is：There is provided a kind of 3D printing metalwork and substrate point
From processing method, including following steps：
(a) before 3D printing, substrate surface is cleaned；
(b) boron nitride coating is sprayed in substrate surface；
(c) it is painted with after boron nitride coating, substrate is dried at a temperature of 280-320 DEG C, treats that boron nitride coating is dried laggard
Row 3D printing is used.
The further technical characteristic of the present invention is, in the step (a), and the substrate surface clean method is to be rushed with water
Wash.
The further technical characteristic of the present invention is, in the step (b), with sponge, hairbrush or spray gun receiving dilution
Meter level boron nitride coating is applied to substrate surface formation boron nitride coating.
The further technical characteristic of the present invention is, in the step (b), the boron nitride coating is uniform, surface not
It must assemble and should not apply too thick.
The further technical characteristic of the present invention is, in the step (c), and the drying temperature is 300 DEG C.
Beneficial effect
The present invention has had the advantage that compared with prior art：
1st, boron nitride is applied on substrate by the present invention, ensures that formation fragility between the object of printing and substrate
Compound, to separate；
2nd, because forming frangible compounds between the object and substrate of printing, somewhat borrowing impulsive force just can be from substrate
It is quick to remove 3D metalworks, machining processes are eliminated, production efficiency is improved；
3rd, do not deformed after printing substrate of the present invention is separated with 3D printing sample, substrate can with Reusability, change with
The situation of a substrate will once be sacrificed by often being printed toward metal 3D printing technique；
4th, boron nitride spreadable substance is also very cheap, reduces cost, and can scrape, be sanded, or is simply washed away with hot water,
Ensure that substrate is reused；
5th, the present invention is simple and practical, reduces metal 3D cost, realizes economical and practical metal 3D printing technique, can
Allow 3D metallic print technologies to be more nearly ground vapour, applied to more industries, and cheaper material can be used.
Brief description of the drawings
Fig. 1 is structural representation after 3D printing.
Wherein：1st, the 3D parts of printing, 2, boron nitride coating, 3, substrate.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
