The present application relates to the technical field of 3D printing, in particular to a five-axis printing shell part support structure generation method, device, equipment and medium. The five-axis printing shell part support structure generation method disclosed by the present application first divides the curved surface of the shell part model into layers to obtain the bottom layer curved surface slice, identifies the overhanging edge to obtain the overhanging boundary line and projects to obtain the projected boundary line, determines the key boundary information, and generates the part support structure accordingly, which can better fit the shape of the part bottom layer and the overhanging condition, is suitable for shell parts such as human skull implants, overcomes the limitation of non-support printing, and the structure is generated according to the specific boundary line, thereby reducing the amount of support material and the difficulty of removal.

A sensor arrangement (2) for detecting an intracranial pressure, said arrangement (2) comprising: a housing (8) defining an internal space (15a; 15b) which is configured for accommodating a pressure sensor device (9) and an electronic control unit (14) to which said pressure sensor device (9) is connected; and fastening means (7; 2b) cooperating with said housing (8) and being configured for mounting said arrangement (2) in a human skull bone (3). Furthermore, the housing (8) is arranged with an opening (11) which is covered by a membrane (12) being made of titanium or a similar thin and flexible material, and is configured for generating vibrations in accordance with an existing outer pressure, said vibrations being transferred to said pressure sensor device (9) via a medium which fills the internal space (15a); wherein said pressure device (9) is located within the internal space (15a) which is formed by said housing (8) and the membrane (12) covering the opening (11); and wherein the sensor arrangement (2) is enclosed within a duct (24) extending from an inlet (25) connected to a cavity within said skull bone (3) and connected to an outlet (26), said duct (24) being configured for guiding a fluid from said inlet (24) to said outlet (26) via said sensor arrangement (2).

The application discloses a bone conduction mobile phone shell and a manufacturing mold and method thereof, which comprises a mobile phone shell body, the mobile phone shell body comprises a first shell and a second shell, the first shell is configured to accommodate a mobile phone body, and the second shell is configured to form an electronic element chamber and realize processing and playing of mobile phone media sound; the first shell is provided with a first opening and a first storage cavity communicated with the first opening; the second shell is arranged on one side of the first shell, the second shell is provided with a second opening and a first accommodating cavity communicated with the second opening, the first accommodating cavity forms the electronic element chamber, and the opening direction of the second opening is opposite to that of the first opening; the bottom plane of the second shell is flush with the first opening, and the bottom plane of the second shell is configured to form a bone conduction surface and contact a human skull; after being processed, the media sound of the mobile phone is conducted to the skull through the bottom plane of the second shell, and the bone conduction surface of the mobile phone shell has good conduction performance.
