With the development of technology, 3D printing has been widely adopted across various industries, becoming an important tool for design and production. At the same time, pearlescent pigments, known for their unique optical properties and aesthetic appeal, have gradually been incorporated into 3D printing materials. This combination not only enhances the visual quality of products but also offers new possibilities for creating more personalized and diverse items.

2. Technical Principles of Pearlescent Pigments

2.1 Composition and Classification of Pearlescent Pigments

Pearlescent pigments are typically made from high-quality inorganic or organic materials, with main components including titanium dioxide, mica, and other minerals. Depending on their optical effects, pearlescent pigments can be classified into the following categories:

· Interference Pearlescent Pigments: These generate interference effects through varying thicknesses of coatings, commonly used in high-end cosmetics and decorative items.

· Metallic Pearlescent Pigments: Containing metallic components, they exhibit significant metallic luster and are widely used in automotive coatings and electronic products.

· Functional Pearlescent Pigments: Featuring specific functions, such as UV resistance and antibacterial properties, they find applications in medical and daily-use products.

2.2 Optical Properties: Interference and Scattering Principles

The optical effects of pearlescent pigments primarily rely on light interference and scattering. When light hits the surface of a pearlescent pigment, part of the light is reflected, while another part penetrates the pigment and interferes with the coating interfaces, resulting in rich color variations. This unique optical characteristic allows pearlescent pigments to display different colors from various angles.

2.3 Achieving Pearlescent Effects in 3D Printing Materials

In 3D printing, pearlescent pigments can be mixed with resins, plastics, and other materials. By optimizing the pigment's particle size and distribution, it can be ensured that the pigments are evenly dispersed during the printing process, achieving the desired pearlescent effect in the final product.

3. Applications of Pearlescent Pigments in 3D Printing
