After selecting with material, can directly produce the part that can use and test, can greatly shorten product development
Cycle (general surface without aftertreatment technology, require that high surfaces can be reserved suitable surplus and carry out machining
Process with postorder surface)；
2) can obtain that there is nonequilibrium state supersaturated solid solution and the entity of uniform tiny metallographic structure, fine and close
Degree almost can reach 100%, and part machinery performance is suitable with Forging Technology gained；
3) use has the laser instrument of high power density, with the laser beam processing metal that hot spot is the least so that
The metal parts processed has the highest dimensional accuracy (reaching 0.1mm) and good surface roughness
(Ra 20～40 μm)；
4) the least due to laser spot diameter, therefore the laser energy density of metal bath is the highest so that use
The metal dust of single component manufactures part and is possibly realized, and alternative metal dust kind is the biggest
Big expansion；
5) be suitable for various complicated shapes workpiece, be especially suitable for inside have complicated abnormal shape structure (as cavity,
Three-dimensional grid), the complex part that cannot manufacture by traditional method；
The 3D printing device advantage of application SLM technology is significant, but there is also deficiency.One substantially
Shortcoming be: need just can carry out after part has printed inside nondestructive inspection, to determine that inside parts has
Without generating defect.This not only makes 3D print production cycle prolongation, and bigger production cost can be caused to waste.
That is: if one part printing-forming completes just to find its internal existing defects, then before institute in print procedure
The powder of consuming, noble gas, electric energy, equipment depreciation, personal expenditures etc. are all just wasted.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that a kind of 3D with nondestructive inspection function prints and sets
Standby, solve conventional 3D printing device and cannot detect a flaw when printing and cause product existing defects, cause waste
Technical barrier.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
Having the 3D printing device of nondestructive inspection function, including working chamber, the top and bottom of working chamber are respectively
Being provided with laser module and formation cylinder, be provided with formation cylinder moving parts in described formation cylinder, formation cylinder moves
Assembly upper end is provided with forming board, and described forming board upper end or formation cylinder sidewall are additionally provided with nondestructive inspection
Instrument, harmless flaw detector connects inside parts quality analysis system, and described nondestructive inspection instrument is provided with multiple,
Multiple described harmless flaw detectors are positioned at forming board upper end or the not Tongfang of formation cylinder sidewall same level
To.
Further, described harmless flaw detector is provided with two, and two described harmless flaw detectors are mutually perpendicular to set
Put.
Further, described harmless flaw detector is that X-ray harmless flaw detector, ultrasonic reflectoscope or electromagnetism are visited
Hinder instrument.
Compared with prior art, the invention has the beneficial effects as follows: present configuration is simple, it is possible to produce printing
During product, product detected a flaw in real time and analyze quality condition, thus stopping when interiors of products existing defects
Only print, it is ensured that the quality of printed product, manufacturing deficiency product can also be reduced simultaneously and expend powder,
The cost such as noble gas and electric energy, has saved the energy and cost.
