Preferably, auxiliary additive is first added in step 1 in metal powder, then is mixed with organic binder；Auxiliary adds
Adding agent is rare earth element powder, carbon dust, iron powder or boron powder；Additive amount is the 0.5~1% of metal powder volume.
The invention has the advantages that the present invention manufactures various unmanageable, complicated metal parts using 3D printing technique,
The shape of part is unfettered, avoids the defect that must use mold in existing manufacturing technology, simplifies process, shorten manufacture
Period improves the manufacture efficiency of difficult-to-machine metal part, is applicable to the preparation of various metals product.
Specific embodiment
The present invention is described in further detail With reference to embodiment, but the present invention is not limited to these realities
Apply mode.
The present invention provides a kind of preparation method of metal material product, this method can be used for preparing a variety of unmanageable
Metal material with property or specific use, be particularly suitable for as：High-speed steel, mould steel, unimach, nickel close
The metallic articles such as gold, high temperature alloy, tungsten alloy, molybdenum alloy, titanium alloy.Specific preparation method is as follows：
Step 1, prepared by raw material
Organic adhesive is added in globular metallic powder and is sufficiently mixed.The preferred epoxy acrylic resin of organic adhesive,
Unsaturated polyester resin, urethane acrylate, polyester acrylate, polyester acrylate resin or amino acrylic resin.Gold
The volume ratio for belonging to powder and organic adhesive is 3:7~7:3.To guarantee the good mobility of slurry, mixed process and stored
Journey should be avoided light-exposed, particularly avoid ultraviolet light, mixed process avoids being mixed into excessive impurity oxygen as far as possible, it is ensured that high temperature sintering matter
Amount.
In order to guarantee the performance of metallic article, it is mixed with organic binder again that a small amount of auxiliary additive is added in metal powder
