Abstract

The invention discloses powder slurry and a curing method of the powder slurry, the powder slurry comprises resin, spectrum conversion particles, photo-thermal conversion particles, an initiator, powder and a dispersing agent, the curing method of the powder slurry comprises the following steps: weighing the resin, the spectrum conversion particles, the photo-thermal conversion particles, the initiator, the powder and the dispersing agent with preset mass, obtaining a mixed slurry, carrying out ball milling on the mixed slurry through a ball mill to obtain the powder slurry, and irradiating the powder slurry through light with a preset wavelength which is one or more of 0.001-10nm and 760nm-1mm. The technical problem of low curing molding precision of the powder slurry is solved.

Description

technical field [0001] The present application relates to the technical field of additive manufacturing, in particular to a powder slurry and a curing method for the powder slurry. Background technique [0002] Additive manufacturing technology based on powder slurry is widely used in aerospace, national defense, energy, environment, automobile and biomedicine to manufacture complex structural parts. Traditional additive manufacturing methods based on powder slurry (powder sintering, dry molding, plastic molding and grouting molding, etc.), there are problems such as loose structure of parts, poor mechanical properties, anisotropy and low efficiency of layered molding. At present, the use of bulk manufacturing technology can avoid the low efficiency of traditional additive manufacturing. , Anisotropy and other defects, however, bulk manufacturing technology mostly uses visible light to cure low-transparency materials such as light-curable resins, and visible light has low en...
