摘要： The present disclosure generally relates to methods for additive manufacturing (AM) that utilize ghost support structure in the process of building objects, as well as novel ghost support structures to be used within these AM processes. The ghost support structures include a portion of powder that is scanned with an energy beam having insufficient power to fuse the powder. The ghost supports control timing of the additive manufacturing process and allow portions of the object to cool to a desired temperature before adjacent portions of the object are scanned.

摘要： The invention relates to a method for manufacturing an object from a material by means of additive manufacturing using a plurality of solidifying devices for solidifying said material in stacked layers by means of electromagnetic radiation. Said method comprises the step of defining, by a data processing unit, at least two solidifying device allocations. In each of said solidifying device allocations said plurality of solidifying devices are allocated to respective parts of said layer such that said parts cover said layer. The method further comprises calculating, by said data processing unit, for each of said at least two solidifying device allocations, respective allocated part manufacturing times representing times for each of said plurality of solidifying devices for solidifying said respective allocated part of said layer, wherein said calculating takes into account an expected disturbance area from solidifying said material by one of said plurality of solidifying devices, wherein said disturbance area relates to at least an expected fume above said layer. The data processing unit then determines the manufacturing throughput time, and selects a definite allocation.
