Background technology
Metal 3D printing technique is gradually ripe at present, is had in fields such as aerospace, medical treatment, automobile, nuclear powers
Body application, but be limited to current 3D printing forming technique, stamped metal part are inevitably lacked with different type, size
It falls into, difference, existing evaluation method are simultaneously not suitable for the defect formed with technologies such as traditional casting, forging, welderings, can not determine difference
The influence of type, the defect of size to the mechanical property of stamped metal part, lead to current metal 3D printing drip molding applies base
The structural member not high to mechanical property requirements is confined in sheet.
It is found by non-destructive testing technologies such as industry CT, ultrasounds, main defect is bubble in metal 3D printing drip molding
(loose), crackle, fusion are bad etc., for the test button of crackle built in preparation, the bad defect of fusion, at present there are mainly two types of
Method produces the crack defect with certain size one is fatigue test is carried out using fatigue tester；Another method
It is to be cut into crackle with plasma or other high energy beams, then in soldering.Defect sample prepared by both methods is right
Tissue, performance of sample etc. have carried out different degrees of destruction, can not effectively be commented the relationship between defect and mechanical property
Valence is suitable only for demarcating non-destructive detecting device.And other types defect, lack effective preset technology at present, therefore
Drip molding preparation method and means with typical metal 3D printing defect are very immature at present.
For the deficiency of existing method, the present invention proposes a kind of test button 3D printing manufacturing process of preset defect, should
Method be arranged inside model when establishing 3D printing mathematical model, by Three-dimensional Design Software different type, size, quantity,
The defect of position distribution, using selective laser fusing (SLM) 3D printing equipment forming.This method can not only careful design preparation
The test button with internal flaw of various complicated shapes, it is ensured that do not destroy metallic matrix continuity, can be used in grinding
Study carefully the relationship between defect and mechanical property.
Invention content
Purpose of the present invention is to provide in view of the defects existing in the prior art a kind of test button 3D printing of preset defect at
Shape method, material structure, performance change caused by test button internal flaw preparation method, are not used to measure mechanical property at present
Can the problem of, and can accurate, purposeful preset more polymorphic type, size, distribution, quantity defect.
The present invention to achieve the above object, adopts the following technical scheme that：A kind of test button 3D printing of preset defect at
Shape method, includes the following steps：
Step 1: according to the actual size and shape of required test button, data are carried out using 3 d modeling software
Modelling；
Step 2: the different types of defect of design a number of, size and distribution, modifies in the three-dimensional model；
Step 3: designed model is carried out slicing treatment, every layer of outline data is obtained, and plan forming path；
Step 4: selecting matched 3D printing metal powder according to the material of test button, correspondingly configured size is selected
SLM 3D printers carry out printing-forming；
Step 5: cut down from substrate stamped metal part with wire cutting, extra backing material is removed, final
To the test button with built-in defect of required shape and size.
Preferably, the type of the defect in step 2 is stomata, merges stamped metal part caused by bad or crackle
Unsound defect.
Preferably, the defect in step 2 is that a kind of or multiclass is mixed.
Preferably, the shape of the test button in step 5 is irregular shape.
Preferably, the SLM 3D printers have good control accuracy, temperature regulating device and oxidation.
Beneficial effects of the present invention：3D printing manufacturing process is introduced the test button for preparing preset defect by the present invention for the first time
In, current sample preparation difficulty is enormously simplified, sample preparation precision is improved.Not using selective laser fusing (SLM) 3D printing equipment
The test button of various complicated shapes can be only prepared, and ensure that the continuity of metallic matrix, while can accurately really
Determine position, the pattern etc. of defect, the relationship of mechanics performance test results analyzing defect and mechanical property can be preferably combined, for gold
The application for belonging to 3D printing drip molding provides strong theories integration.
Description of the drawings
Attached drawing 1 is the test button 3D printing manufacturing process flow diagram of preset defect of the present invention；
Fig. 2 is the schematic diagram that (SLM) technique 3D printing equipment is melted in selective laser.In figure：1 laser, 2 protective gas, 3
Powder-laying roller, 4 raw material powder storehouses, 5 powder feeding storehouse lifting platforms, 6 stomata class defects, 7 forming platform lifting platforms, 8 substrates, 9 crack defects,
10TC4 titanium alloy samples, 11 forming cavities, 12 laser beams, 13 scanning galvanometers.
Specific implementation mode
The present invention is further described for 1, Fig. 2 and embodiment below in conjunction with the accompanying drawings.
Case study on implementation：
Present case is to prepare a TC4 titanium alloys sample 10 with 3 gas hole defects 6 and 1 Crack 9, the ruler of sample
Very little is 20*20*20mm, diameter 0.05mm~0.1mm of stomata, crack length 8mm, and specific preparation process is as follows：
