3D PRINTING A METAL GREEN PART
In one example, a process for making a metal green part includes forming a 10 µm to 100 µm thick layer of metal powder, jetting a UV photopolymerizable binder composition on to the layer of metal powder at 0.09 mg/cm2 to 0.60 mg/cm2 in a pattern representing a slice of the green part, irradiating th...

| description | In one example, a process for making a metal green part includes forming a 10 µm to 100 µm thick layer of metal powder, jetting a UV photopolymerizable binder composition on to the layer of metal powder at 0.09 mg/cm2 to 0.60 mg/cm2 in a pattern representing a slice of the green part, irradiating the patterned powder with a total of 20 J/cm2 to 40 J/cm2 of UV light in one or more 10 ms to 80 ms flashes to polymerize a binder in the binder composition, and repeating the forming, jetting, and irradiating for each slice of the green part.
Dans un exemple de la présente invention, un procédé de fabrication d'une pièce crue métallique comprend la formation d'une couche de poudre métallique épaisse de 10 µm à 100 µm, la projection d'une composition de liant photopolymérisable aux UV sur la couche de poudre métallique de 0,09 mg/cm2 à 0,60 mg/cm2 selon un motif représentant une tranche de la pièce crue, l'irradiation de la poudre en motifs avec un total de 20 J/cm2 à 40 J/cm2 de lumière UV sous la forme d'un ou plusieurs éclairs de 10 ms à 80 ms pour polymériser un liant dans la composition de liant, et la répétition de la formation, de la projection et de l'irradiation pour chaque tranche de la pièce crue |
