In this context, the material that there are rights to independence to require feature, device and method are proposed.Material, device and method
Design scheme by being obtained in dependent claims and specification.
The design of material invented at all is for manufacturing component and including the mixture formed by metal powder and flow promortor.
In order to manufacture component, material is applied on the load bearing member, and is melted by laser beam after being applied on the load bearing member, and makes gold
Belong to powder curing into component.
Flow promortor includes metal oxide particle, which includes the oxygen of base metal or transition metal
Compound.Optionally or addedly, flow promortor includes the molecular compound of metal oxide, which includes base metal
Or the oxide of transition metal.
Therefore, flow promortor be may include not only base metal can also include transition metal, such as silicon metal oxygen
The molecular compound of compound particle or metal oxide.
If the energy applied in heating material is insufficient, flow promortor is partly melted by laser beam together, and portion
Divide and is not melted.Flow promortor is entered as particle residue in molten metal powder in other words metal, or with molten bath
In new phase.The material of fusing can also be improved herein, that is the material of fusing and/or the mechanicalness of molten metal powder
Can, such as it is particularly the case for ODS alloys (oxide dispersed strengthening oxide dispersion intensifyings).
In the embodiment of the material of proposition, flow promortor has hydrophobic performance.
Built using the oxidation with metal or transition metal, such as siloxanes or aluminium oxide or molecular compound as flowing
Auxiliary agent.
Flow promortor proportion in entire material is, for example, 0.1% to maximum 1%.The ratio generally corresponds to quality
Percentage.Therefore material quality include x%, 0.1% flow promortor and 100-x%, such as 99.9% metal powder.
Metal powder is for example formed by aluminium, steel, nickel or titanium, wherein metal powder granulates in embodiments have 10 μm extremely
200 μm of size.
According to the present invention in manufacturing the method for component, the material proposed to be applied on the load bearing member, and
It is melted by laser beam after being applied on the load bearing member, the also metal powder as the component part of material other than flow promortor
End is cured or hardens into component.
Device according to the present invention for production material includes mixing apparatus, which is designed to metal
Powder is mixed with each other with flow promortor, and the material is thus made.
In design scheme, which includes the first container for measuring equipment with first and measures equipment with second
Second container.Metal powder is stored in the first container at this, flow promortor is stored in second container.First measures equipment quilt
It is designed as measuring the metal powder of the first amount from the first container and is supplied to mixing apparatus.Second measurement equipment be designed to from
The flow promortor of the second amount is measured in second container and is supplied to mixing apparatus.
By may be implemented equipped with the flow promortor being mixed into metal powder to prepare material, manufactured in production
In method, for example, in 3 D-printing method improve metal powder mobility.
In the method for manufacturing component, wherein using adding type manufacturing method, it is added to the metal powder of flow promortor
It is for example melted by lasing light emitter at end.Metal powder usually has the granular size of the range between 10 μm to 200 μm.By continuing
Repeatedly melt realizes component of the manufacture with complex geometric shapes by the layer that metal powder is formed on the load bearing member.Herein by
The achievable mechanical features value of metal component made of the material, such as yield limit, tensile strength and/or extension at break exist
It is evenly distributed on manufactured component.In addition, passing through the variation of at least one process variable of laser, the power of such as laser
And/or the movement velocity of laser beam variation can on entire component adjustment member different mechanical property requirements.
Further include the material of flow promortor other than metal powder by setting, in rapidoprint and and then in processing gold
Process stability is ensure that when belonging to powder.Include the metal powder based on aluminium, steel or iron, nickel or titanium material due to be mixed with stream
Dynamic auxiliary agent has improved mobility compared with pure metal powder, and thus the material with metal powder is on being applied to load-bearing part
When ensure that and be applied evenly.By the case where metal powder is mixed with flow promortor in the material, due to mobility
It is also beneficial to be mixed with the suction and sieving of the metal powder of flow promortor.The ratio that flow promortor accounts in material for example relies on
Size, the Size Distribution of particle in metal powder granulates, also rely on environment temperature and humidity.
The flow promortor of metal powder fluctuates very little as material components.Material is also reduced by flow promortor to inhale
The trend of hygroscopic gas.
In manufacture material, i.e., in embodiments mixing material when, based on aluminium, steel, nickel or titanium metal powder mixing
A small amount of flow promortor.Such as siloxanes or aluminium oxide are used as flow promortor.The amount of flow promortor or institute in the quality of material
Accounting example is the small percentage range of units to maximum 5% or maximum only 1%, such as 0.1%.It is to be processed, i.e. fusion
The mechanical features value of the metal powder of change is unaffected due to a small amount of flow promortor.Flow promortor is commonly attached to metal powder
On, and there is hydrophobicity.Gold is significantly improved by the flow promortor or corresponding flowing auxiliary material that are mixed into metal powder
Belong to the mobility of powder.
In the method for manufacture component, wherein successively manufacture component in principle, when applying material on the load bearing member and in turn
Apply the process for the stabilization that the when of being mixed with the metal powder of flow promortor ensure that when applying material on the load bearing member.Due to
Using only a small amount of flow promortor, therefore the mechanical features value of metal powder is not influenced.Due to flow media be it is hydrophobic, because
This also avoids metal powder and absorbs moisture from environment.
The further advantage and design scheme of the present invention is obtained from the description and the appended drawings.
It is evident that it is above-mentioned and following it may also be noticed that feature not only can by the combination that illustrates respectively,
It by other combinations or can also be used alone, as long as without departing from the scope of the present invention.
