  • Patent number: 11590690
    Abstract: A printer unit (100) for a 3D-printing apparatus. The printer unit comprises a printer head (105) comprising a nozzle (110) arranged to deposit printing material from the printer unit, a pressure sensor (120) configured to sense a pressure exerted on the printer head from the printing material, and a control unit (130) coupled to the pressure sensor. The control unit is configured to control the speed of the printer head based on a transfer function from the pressure sensed by the pressure sensor to a desired speed of the printer head, in order to maintain a constant deposition of the amount of printing material per length unit of deposited printing material.

  • Patent number: 11273597
    Abstract: A printer unit (100) for a 3D-printing apparatus for deposition of a printing material, as well as a method of 3D printing, is provided. The printer unit comprises a printer head (105) comprising a nozzle (110). The printer head is resiliently suspended in the printer unit in a vertical direction by at least one resilient means (120), allowing a vertical movement of the printer head during deposition of the printing material. The suspended printer head in its equilibrium is positionable above the underlying material at a vertical distance (?z1) before deposition. During deposition of printing material, the at least one resilient means is configured to become biased by a vertical force (F3) on the nozzle from the printing material on the underlying material, such that the printer head moves from its equilibrium into a position at a desired vertical distance (?z1) from the underlying material.

  • Patent number: 10348403
    Abstract: A light emitting device (100) for emitting a beam of light is disclosed. The light emission of the light emitting device (100) comprises an embedded code. The light emitting device (100) comprises a beam shape controller (102) for controlling a shape of the beam of light and a first processor connected to the beam shape controller, arranged for generating the embedded code. The first processor (104) is further arranged for embedding a message in the embedded code based on the shape of the beam of light. This allows the light emitting device (100) to communicate information to a receiving device based on its effect area (i.e. the illuminated area). This information may, for example, comprise information about the beam shape and size, which may be used to determine an area wherein the receiving device is located relative to the light emitting device (100).
