  • Publication number: 20240090940
    Abstract: A system having an electrode probe and a temperature sensing device, wherein the temperature sensing device is positionable within the electrode probe. The probe can have an elongate electrode body, at least two electrode contacts disposed on the electrode body, and a lumen defined within the electrode body, and the temperature sensing device can have an elongate outer body having a lumen, an elongate inner sensing body disposed within the lumen, and at least one temperature sensor disposed on the elongate inner sensing body. The system in certain embodiments can also have a controller configured to receive temperature information from the temperature sensing device and use the temperature information to adjust energy supply to at least one of the at least two electrode contacts.

  • Publication number: 20240086583
    Abstract: A method includes: accessing a part model comprising a three-dimensional representation of a part; accessing a material profile relating exposure energy and three-dimensional polymerization geometry of a material selected for the part; segmenting the part model into a set of model layers; detecting a first upward-facing surface in the part model; defining a first model volume in a first model layer, adjacent the first upward-facing surface, and fully contained within the part model; based on the material profile, calculating a first exposure energy predicted to yield a first three-dimensional polymerization geometry approximating a first contour of the first upward-facing surface when projected onto the material during a build; populating a first print image with the first exposure energy in a first image area corresponding to the first model volume in the first model layer; and storing the first print image in a print file for the part.
