    Abstract: A component (1) is formed by means of additive manufacturing by repeating a series of cycles, where each cycle has a depositing step for forming a powder layer (22) of substantially constant thickness; a pre¬ heating step, for pre-heating the powder layer (22); and a melting step, for melting some areas of said powder layer (22) by means of an energy beam so as to form a horizontal section (170) of the component (1) that must be obtained; at the end of all cycles, the top surface (21) of the horizontal section that has been formed is lowered until it reaches a predetermined height (Q); the pre-heating step is performed by moving a heat source (30) above the powder layer (22) at the same time as the depositing step, at least for an initial part of the pre-heating step.

    Abstract: Pulse-position synchronization is provided in miniature structure manufacturing processes which is carried out in a fabrication tool (10) having a target (23), a source (11) of energy generating pulses of energy, and a control unit (15) operatively coupled to the source (11) of energy and the target (23). The technique includes the steps of exposing a target (23) to a first pulse of energy, pausing the exposure of the target (23) while providing relative motion between the target (23) and the energy source (11) at a predetermined maximum speed, and slowing (or stopping) relative motion between the target (23) and the energy source (11), while exposing the target (23) to a second pulse of energy. The fabrication tool (10) employing the pulse-position synchronization can be operated by the control unit (15) in either patterned "additive" or patterned "subtractive" modes of operation.

    Abstract: Apparatus (10) for performing patterned cleaning of substrate surfaces (11) includes substrate (11), energetic beam (12) directed to the substrate (11), material carrier element (14) having a deposition layer (16), and a control unit (8) operating the apparatus (10) in either a "material removal" or a "material transfer" mode in a predetermined sequence. In the "material removal" mode, the following steps are followed which include displacing the material carrier element (14) from the interception with the energy beam (12) and allowing impinging of the energy beam (12) on the surface of the substrate in a predetermined patterned fashion so that the material of the substrate surface is disintegrated at predetermined locations of the substrate surface (11). After the first cleaning, the control unit (18) changes the mode of operation to the "material transfer" by moving the material carrier element (14) into position intercepting with the energy beam (12) so that the material of the deposition layer (16) is deposited on the surface of the substrate (11).
