The present invention provides a 3D printing sound guide pad material, a sound guide pad, and a method and device for 3D printing a sound guide pad. The 3D printing sound guide pad material is composed of the following components: 8%-10% polyvinyl alcohol, 1%-2% agar, 5-8% glycerol, 0.01%-0.1% preservative and the balance of ultrapure water. The sound guide pad obtained by using the above 3D printed sound guide pad material not only has good mechanical properties and acoustic properties, but also has similar impedance to the human body, has good biocompatibility, good moisturizing effect, no irritation to the skin, and can be recycled. |
