Embodiment Construction
[0022] The 3D printing drug shell of the present invention can control the drug release rate to be constant, and its structure is a sphere with four cylindrical cavities with an included angle of 109.47°; the printing material is a polyvinyl alcohol wire; the application Occasionally, controlled-release drugs and occasions with high requirements for drug stability; the active ingredients of the drug are released at a constant speed; the manufacturing method is printing using an FDM type 3D printer.
[0023] First carry out the digital modeling of the enclosure. Use CAD computer-aided drawing software to build a regular tetrahedron with a side length of 10mm. Find the geometric center of the tetrahedron. Use this geometric center as the center of the sphere to make a sphere with a diameter of approximately 12.4mm. At this time, the tetrahedron is connected to the sphere. Connect the four corners of a regular tetrahedron to its geometric center to form four straight lines with th...
