Abstract
A method for manufacturing ear devices that are individualized for individual. Data of the three-dimensional shape of each individual's area of application for a haring device is provided. Individual shells for the hearing devices are construed by respectively depositing commonly a layer of one of a liquid and a powderous material and solidifying by a laser arrangement in the layer individually shaped layers of the individual shells, thereby controlling the laser arrangement with the data.
Claims18
An apparatus for manufacturing individualized ear device shells comprising a support for powder or liquid material, a source arrangement generating in the powder or liquid material at said support a spot of increased energy, a control arrangement controlling a location of said spot to move along at least two first closed loops in said material in a first cycle and subsequently along at least two second closed loops adjacent and substantially along said first closed loops in a second cycle.
An apparatus for manufacturing individualized ear device shells comprising:
- a support;
- means to deposit liquid or powder material on the support;
- means to solidify the material in individually shaped layers;
- and
- a control unit having a data input, wherein the control unit controls the means to solidify based on data of a three-dimensional shape of an individual's area of application to solidify the material in layers corresponding to individual contours of each layer.
