Titanium
Titanium is a strong, lightweight, and biocompatible metal widely used in the aerospace, medical, and automotive industries. 3D printing with titanium offers the benefits of reduced material waste and the ability to create complex shapes and structures. However, printing with titanium requires specialized equipment due to the high melting point and reactive nature of the metal.
Copper
Copper is an excellent conductor of electricity and heat, making it ideal for electrical components and heat sinks. 3D printing with copper offers the advantage of cost-effective production of complex copper components with high thermal conductivity. Copper prints can be further polished or patinated to achieve different surface appearances.
Nickel
Nickel is a strong and corrosion-resistant metal commonly used in the aerospace, oil and gas, and chemical industries. It is often alloyed with other materials to enhance its properties. 3D printing with nickel allows for the creation of complex structures with high precision and repeatability. Nickel prints can be heat-treated or machined for additional strength and surface finish optimization.
Bronze
Bronze is an alloy of copper and tin, offering a balance between strength, ductility, and corrosion resistance. 3D printing with bronze allows for the production of decorative objects, jewelry, and artistic sculptures. Bronze prints can be further polished or patinated to achieve desired surface appearances.
