Abstract: The present invention relates to a method for producing an adhesive bond, comprising the steps of curing (S101) a light-curing adhesive material by means of light; detecting (S102) a degree of polymerization of the adhesive material; and terminating (S103) the curing at a specified degree of polymerization.

Abstract: A holding device (100) for a round dental blank (200). The holding device has an open ring element (101) for laterally gripping the dental blank (200) and a closing element (103) for closing the ring element (101) at various positions.

Abstract: A method for analyzing a print head (103), including the steps of driving (S101) a piezo element within the print head with a sequence of voltage profiles; and detecting (S102) a sound level, a current flow, a resistance, an impedance, and/or a temperature of the print head during the driving.

Abstract: A method for setting a drop shape in a printing process, including the steps of controlling (S101) a piezo element of a printing nozzle by a first voltage profile; detecting (S102) an electric current value averaged over the first voltage profile or a sound amplitude averaged over the first voltage profile; controlling (S103) the piezo element of the printing nozzle by a second voltage profile; detecting (S104) an electric current value averaged over the second voltage profile or a sound amplitude averaged over the second voltage profile; and selecting (S105) the voltage profile with the lower detected current value or the lower detected sound amplitude.

Abstract: A method for preventing deposits of a printing liquid at a nozzle plate (101) of a print head within a 3D printer (100), including the step of increasing a saturation level of a carrier liquid (103) of the printing liquid in the air in front of the nozzle plate (101).

Abstract: A method for removing deposits in a print head of a 3D printer, including the steps of supplying (S101) a liquid having a granular solid to the print head; and setting into vibration (S102) the liquid in the print head.

Abstract: The invention provides a method of preparing hot beverages by brewing up a particulate substance extractable by means of water. Thereby, the substance received in a brewing chamber is brewed up by brewing water that has a temperature above the normal boiling point of water, preferably 110° to 130° C., but still is in the fluid state of matter. The thus brewed beverage is cooled to a temperature below the normal boiling point of water before it flows to a beverage outlet. A significant advantage of this method is that the substance is much more efficiently extracted. For cooling the thus brewed beverage, preferably a heat exchanger is used through which fresh, not yet heated brewing water flows to thereby cool it.
