Abstract: A compound particle and a product manufactured from the compound particles are provided to solve a problem of a rough surface of a product made by additive manufacturing technology. The compound particle has a metal core and a ceramic shell wrapping the metal core. A melting point of the ceramic shell is higher than a melting point of the metal core.

Abstract: An additive manufacturing method is provided. A plurality of powder layers is stacked on a supporting plate in sequence. Energy beams are provided to the powder layers in sequence by using an energy source, such that each of the powder layers is at least partially shaped. The powder layers are heated by using a temperature control device, so as to control a temperature of each of the powder layers being shaped.

Abstract: An additive manufacturing apparatus including a supporting plate, an energy source and a temperature control device is provided. A plurality of powder layers are adapted to be stacked on the supporting plate in sequence. The energy source is adapted to provide energy beams to the powder layers in sequence, such that each of the powder layers is at least partially shaped. The temperature control device is adapted to heat the power layers, so as to control a temperature of each of the powder layers being shaped.
