Abstract: An apparatus and a method for powder bed fusion additive manufacturing involve a multiple-chamber design achieving a high efficiency and throughput. The multiple-chamber design features concurrent printing of one or more print jobs inside one or more build chambers, side removals of printed objects from build chambers allowing quick exchanges of powdered materials, and capabilities of elevated process temperature controls of build chambers and post processing heat treatments of printed objects. The multiple-chamber design also includes a height-adjustable optical assembly in combination with a fixed build platform method suitable for large and heavy printed objects. A side removal mechanism of the build chambers of the apparatus improves handling and efficiency for printing large and heavy objects. Use of a wide range of sensors in the apparatus and by the method allows various feedback to improve quality, manufacturing throughput, and energy efficiency.

Abstract: In a method of operating an irradiation system (10) for irradiating layers of a raw material powder with electromagnetic or particle radiation in order to produce a three-dimensional work piece (110) it is determined whether a region of a raw material powder layer (11) to be selectively irradiated with electromagnetic or particle radiation in accordance with a geometry of a corresponding layer of the work piece (110) to be produced is affected or substantially unaffected by particulate impurities. Upon selectively irradiating the region of the raw material powder layer (11) with electromagnetic or particle radiation, an energy density applied to the region of the raw material powder layer (11) by a radiation beam (14a, 14b) is controlled in such a manner that the energy density is higher in case it is determined that the region of the raw material powder layer (11) is affected by particulate impurities than in case it is determined that the region of the raw material powder layer (11) is substantially unaffected by particulate impurities.

Abstract: A control system for thermo optical control of focus position of an energy beam in an additive manufacturing apparatus has a first doped medium and a second doped medium, each of which is optically transparent and doped with a dopant. The first doped medium has a positive thermo-optical coefficient (dn/dT) and the second doped medium has a negative thermo-optical coefficient (dn/dT) and is in series with the first doped medium. An energy beam input or coupling is configured to generate or receive an energy beam that is required to be controlled, the energy beam being within a first wavelength range and directed towards the first and second doped mediums. An absorbed beam input or coupling is configured to generate or receive at least one absorbed beam in a second wavelength range which is different from the first wavelength range, the absorbed beam being directed towards the first and second doped mediums. The first and second doped mediums have a higher beam absorption characteristic in the second wavelength range than in the first wavelength range, causing the absorbed beam to have a higher absorption than the energy beam in the first and second doped mediums and the first and second doped mediums each have a coating which allows transmission at both the first and the second wavelength ranges.
