A novel method for two-dimensional or three-dimensional photo-thermal printing of metals, oxides, alloys, and metal composites to produce objects having predetermined shapes is presented. The method comprises: providing a metal ion solution on a substrate; focusing modulated laser light with an objective lens system into the solution on the substrate, thereby causing a microbubble to form and attaching reduced metal ions to the substrate; and moving the focus of the modulated laser light in the x, y, and z directions to continuously form new microbubbles on the previously deposited structure and directly attach reduced metal ions to the previously deposited structure as metal, metal oxide, alloy, or metal composite until the predetermined shape of the object has been produced. The method can be carried out using both layer by layer printing and vector printing.

A stress controlled layer is constituted to include a compressive stress applied part that is a region to which a compressive stress is applied and a compressive stress non-applied part that is a region different from the compressive stress applied part. In a solidifying step, scanning of a laser beam or an electron beam is performed while a scanning direction for the compressive stress applied part is different from a scanning direction for the compressive stress non-applied part such that the compressive stress applied part expands further than the compressive stress non-applied part or the compressive stress non-applied part shrinks compared with the compressive stress applied part based on a relationship between the scanning direction and an expansion quantity or a shrinkage quantity at a time of temperature change or at a time of heat treatment.

An additive manufacturing system may include an energy source, an optical system to modify and direct an energy beam from the energy source toward a component to form a melt pool, and a material delivery device to deliver material to the melt pool. The optical system may form an annular energy beam, direct the annular energy beam toward the component, receive at least a portion of thermal emissions produced by the annular energy beam and the melt pool, and direct the portion of the thermal emissions toward an imaging device, which may be used to control the energy source.

A three-dimensional modeling device includes a table supporting a powder material and a model created from the powder material, a processing section disposed so as to face the table and obtaining the model by processing the powder material, and a rotation unit causing the table to rotate relative to the processing section around a rotary axis. The processing section has a plurality of processing units disposed around the rotary axis. The processing units supply the powder material to the table, preheat the supplied powder material, and emit an energy beam to the preheated powder material.
