The technology disclosed relates to high utilization of donor material in a writing process using Laser-Induced Forward Transfer. Specifically, the technology relates to reusing, or recycling, unused donor material by recoating target substrates with donor material after a writing process is performed with the target substrate. Further, the technology relates to target substrates including a pattern of discrete separated dots to be individually ejected from the target substrate using LIFT.

A laser beam is irradiated onto material powder on a manufacturing table to solidify the material powder and form a solidified layer. The material powder is further deposited on the solidified layer and the laser beam is irradiated onto one part of the material powder to solidify the material powder. They are repeated to manufacture a manufactured object. An irradiation output value of the laser beam is determined based on measurement information regarding a deposition surface before depositing the material powder or regarding a surface state of the material powder after deposition that is acquired by a camera. Alternatively, the aforementioned irradiation output value is determined based on parity information regarding a number of solidified layers that were already solidified by irradiation of the energy beam, or determined in accordance with an irradiation output value used when solidifying a solidified layer solidified prior to deposition of the deposited material powder.

A method of making a workpiece in an additive manufacturing process includes determining a preferred angular orientation of the grid array about a build axis extending perpendicular to a layer to be built for a first layer of a workpiece. The preferred angular orientation is selected to align an edge of one or more pixels with an edge of the layer of the workpiece being built. The method further includes orienting a patterned image of radiant energy to the preferred angular orientation by rotating a projector before solidifying a portion of a resin that forms the first layer of the workpiece.
