Titanium is a very strong, lightweight, corrosion-resistant material and is used mostly for medical parts production. 3D printed titanium has a matte gray finish with a slightly rougher and less defined surface.
Aluminum alloys feature good chemical resistance, are very lightweight, and feature one of the best strength-to-weight rations of any metal. It is the choice of many in the aerospace and automotive industries for its abilities to withstand harsh conditions.
Stainless Steel is a good material for printing both functional and spare parts in 3D. The material is easy to maintain because it attracts little dirt and never rusts. Stainless is used to offer solid pieces and essential hygienics in medical, aeronautical, automobile and domestic products industries.
Inconel is a high strength, corrosion resistant nickel chromium super alloy ideal for parts that will experience extreme temperatures and mechanical loading.
Copper is a metal known for its fantastic thermal and electrical conductivity. Ideal applications for 3D printing in copper include induction coils, heat exchangers and electrical wiring.
Maraging Steel is a steel powder that’s characterized by having excellent strength combined with extreme toughness. Parts are easily machinable after the building process and can be easily post-hardened.

Super alloys are an important group of high-temperature materials used in the hottest sections of jet and rocket engines. They are based on nickel, cobalt or iron with large additions of alloying elements to provide strength, toughness and durability at high temperature.
- PA 6
- PA 11
- PA 12
- Glass filled
Nylon is a polymer know for its high durability, strength and flexibility. It is ideal for printing functional parts and prototypes due to outstanding mechanical properties, and good chemical, impact and heat resistance. Parts printed in Nylon can be easily post-processed in any color.
ULTEM 9085 resin is a flame-retardant, high-performance thermoplastic. It features a high strength-to-weight ratio, excellent heat resistance and high impact strength. It is an ideal material for use in the aerospace industry.
Carbon PA is a composite material in which chopped carbon fibers are incorporated into a polyamide matrix, creating one of the highest performing 3D printing polymers in the industry. It is ideal for high-end mechanical applications.
There are many different photopolymer resins available for 3D printing. They vary in strength, heat resistance, static dissipative qualities and other mechanical properties that allow engineers to produce unique parts for niche applications.
- Carbon PEEK
- Ceramic PEEK
PEEK (Polyetheretherketone) is an engineering thermoplastic characterized by properties ranging from high-temperature performance to mechanical strength and excellent chemical resistance. PEEK 3D printing is likely to be a key driver for the use of AM technologies in mass production.
