  • Publication number: 20190152142
    Abstract: A three-dimensional printing apparatus includes a re-coater including a leveler that levels off a powder material, a powder spread guide including a contact surface that contacts with the powder material, and a transfer device that transfers the re-coater and the powder spread guide in a first direction. The transfer device retains the powder spread guide so that a lower end of the contact surface of the powder spread guide is kept at a height lower than the powder material on a feed region, the contact surface is disposed forward along the first direction relative to the leveler, and at least a portion of the contact surface passes outside a build region with respect to a second direction perpendicular or substantially perpendicular the first direction. In transferring the powder spread guide, the contact surface transfers at least a portion of the powder material that contacts with the contact surface to an inside of the build region.
