  • Patent number: 10112342
    Abstract: A method for determining a bed temperature setpoint for use with a powder in a selective laser sintering machine is disclosed. The method includes the step of providing a powder comprising a polymer for use in a selective laser sintering machine. The method further includes the step of determining a ratio of a liquid portion of the powder to a solid portion of the powder as a function of temperature within a temperature range. A bed temperature setpoint is selected in the temperature range corresponding to a desired ratio of the liquid portion of the powder to the solid portion of the powder. A temperature of a bed of a selective laser sintering machine is set to the selected bed temperature setpoint, and a part is built from the powder using the selective laser sintering machine.

  • Patent number: 10094628
    Abstract: A method of manufacturing a component susceptible to multiple failure modes includes generating a stereolithography file including a geometry of the component. The geometry of the stereolithography file is divided into a plurality of layers. Each of the layers includes a first portion and a second portion of the component. Energy from an energy source is applied to a powdered material such that the powdered material fuses to form the first portion and the second portion of each of the plurality of layers. Applying energy from the energy source to form the first portion of the plurality of layers includes operating the energy source with a first set of parameters and applying energy from the energy source to form the second portion of the plurality of layers includes operating the energy source with a second set of parameters. The first set and second set of parameters are different.

  • Patent number: 10086559
    Abstract: A system for online monitoring powder-based 3D printing processes and method thereof are disclosed. A uniform light source having a single wavelength provided by the system is irradiated onto the powder layer before and after applied with glue. Intensities of such reflected images are obtained and subtracted from each other in an image process procedure. A difference obtained through the subtraction is compared with an original 3D model in a computer. If any defect is found such as being larger than a threshold value, the powder-based 3D printing processes will be terminated. Therefore, the technical effects of online printing processes monitoring, time saving and printing resources saving will be achieved.

  • Patent number: 10035188
    Abstract: The invention relates to a method for layered production of a three-dimensional object, wherein a powdery or fluid building material, which can be solidified by the effects of electromagnetic or particle radiation, is applied in layers having a layer thickness d, and the locations in each layer which correspond to a cross-section of the object allocated to said layer are solidified by means of electromagnetic or particle radiation. According to the invention, each cross-section consists of a contour region and an inner region and the method comprises the following sub-step: in a sequence of N successive cross-sections, wherein N is a whole number greater than 1, a partial region is defined in every cross-section as a critical region and the rest of the cross-section is defined as a non-critical region, a number of N layers are applied successively, without solidification of the non-critical regions.

  • Patent number: 9977425
    Abstract: Method, and corresponding system, for producing an alert during manufacture of a part formed by a plurality of layers. The method includes determining the sensor data values at the working tool positions of each of the plurality of layers based on a correlation of the values of the sensor data relative to time and the working tool positions of each of the plurality of layers relative to time. During the manufacturing process, the sensor data values at the working tool positions of at least one of the plurality of layers are compared to reference data values at the working tool positions for the at least one layer to determine a comparison measure for the at least one layer. An alert is transmitted if the determined comparison measure of a layer is not within a defined range. A defined action is applied to the manufacturing process based on the transmitted alert.
