Abstract: A method for producing a three-dimensional work piece comprises the steps of applying a raw material powder onto a carrier (16), and selectively irradiating electromagnetic or particle radiation onto the raw material powder applied onto the carrier (16) by means of an irradiation unit (18) in order to produce the work piece from said raw material powder on the carrier (16) by a generative layer construction method, wherein the irradiation unit (18) comprises a radiation source (24) and a plurality of optical elements (30, 32, 34, 35). Operation of the irradiation unit (18) is controlled in dependence on an operating temperature dependent change of at least one optical property of at least one optical element (30, 32, 34, 35) of the irradiation unit (18).

Abstract: A carrier arrangement (30) comprises a carrier element (34) having a carrier surface (36) and a plurality of supporting elements (38) attached to the carrier element (34), wherein each supporting element (38) has a supporting surface (40) extending from the carrier surface (36) of the carrier element (34) and being adapted to interact with a first surface (42) of a component (32) to be repaired.

Abstract: A method of teaching a skill, such as, for example, hunting, tracking, law enforcement, terrorist response, self-defense, or game-playing technique, whereby the student is exposed to the perspective of a relevant person, animal, or object, such as, for example, a game player, victim, criminal, terrorist, animal, or ball, whose identity is determined by the nature of the skill, and wherein a mechanism, such as, for example, video, computer animation, virtual reality, or role-playing, is used to impart the perspective. The method broadly comprises the steps of identifying a behavior of the thing, wherein the behavior is related to the skill; modeling a perspective of the thing related to the behavior in terms understandable by the student; implementing the model using a suitable mechanism; and introducing the student to the mechanism such that, through the mechanism, the student is able to experience the perspective of the thing and to thereby better understand the behavior and the skill.
