Laser printing materials mainly include core consumables such as toner and photosensitive drums (light guide drums), as well as special materials for different application scenarios (such as ceramic 3D printing materials). The following are the specific classifications:

1 Carbon powder

Single-component: Contains only toner and needs to be transferred to the photosensitive drum after being charged through the developing roller.

Two-component: Containing toner and magnetic carrier, it is adsorbed and transferred through a magnetic roller. ‌

Photosensitive drum (light guide drum

Organic photoconductive materials (OPC drums) : Mainstream materials, low cost, environmentally friendly, and performance enhanced through nano-coating technology. ‌

Toner cartridges, cadmium sulfide cartridges, etc. : Early materials, gradually phased out due to pollution or cost issues. ‌

Ceramic 3D printing materials

Oxidiz-based ceramics: such as alumina and zirconia, are suitable for high-hardness components.

Nitrided ceramics: such as silicon nitride and aluminum nitride, have excellent high-temperature resistance.

Bioceramics: Used in the medical field, such as artificial bones. ‌

2. Other consumables

Developing roller, cleaning scraper, charging roller, etc. : They need to be replaced regularly to maintain print quality. ‌

Fixing roller: Heat to solidify the carbon powder, and the material needs to be heat-resistant. ‌

3. Environmentally friendly materials

Bio-based inks and degradable toner cartridges: Reduce pollution and conform to industry trends. ‌
