  • Patent number: 11884013
    Abstract: A three-dimensional modeling device includes a plasticizing section for plasticizing a material to generate a shaping material, a stage on which the shaping material is stacked, a nozzle which has a nozzle opening, and ejects the shaping material from the nozzle opening toward a modeling area on the stage, a transfer mechanism section for changing a relative position between the nozzle and the stage, and a heating section having a heater and a heating member for heating the shaping material stacked in the modeling area with heat supplied from the heater. The nozzle opening is located between the stage and the heating section in a stacking direction of the shaping material, the heating section is configured so that a relative position to the stage changes together with the nozzle, and the heating member covers at least the modeling area when viewed along the stacking direction.

  • Publication number: 20180272537
    Abstract: A robot control device detects a detection target position, which is a position of a detection target, from a first image obtained by causing a first camera disposed in a first robot to image the detection target. The robot control device includes a control unit that detects the detection target position from the first image, and that corrects the detection target position, based on first reference position information stored in advance in a storage unit and indicating a first reference position which is a reference position of a first reference marker, and first detection position information indicating a first detection position which is a position detected based on the first image and which is a position of the first reference marker included in the first image.
