An artificial nipple is formed of an elastomeric polymer by use of 3D printing after imaging of a mother's breast in an active state of lactation. The artificial nipple used as an attachment to a baby bottle or as the nipple component of a pacifier. Use of an artificial nipple formed in this manner mitigates a problem with nipple confusion, as may otherwise manifest in newborn offspring.

A filming method of probe and the probe made by the filming method, the method includes following steps: spraying hydrophilic matrix material on the rigid member; injecting liquid polyethylene glycol into an interior, letting the polyethylene glycol coagulate; cutting out the solid polyethylene glycol, letting the cutting surface and the perimeter of the rigid member to be formed in a smooth plane; letting the wedge end of the rigid member insert a liquid latex vertically for immersion, picking up the rigid member and dripping residue, air drying the adhesive layer of the rigid member; upward setting the wedge end of the rigid member, and letting the latex film be heated, melting the solid polyethylene glycol and letting the polyethylene glycol drain away. The method can minimize the nonlinear deviation, simplify the technological process, improves product quality and manufacturing efficiency.
