Advantages and uses of PEEK, the advanced and extremely performing material that is revolutionizing the Additive Manufacturing world
What is PEEK?
PEEK, the most advanced material among the semi-crystalline thermoplastics, guarantees extreme performances combining excellent mechanical and thermal properties, as well as unbeatable chemical resistance against high temperatures (up to 200°C) and in corrosive environments.
The advantages of using PEEK in Additive Manufacturing
There are several advantages resulting from the production of PEEK functional prototypes and finished parts through additive manufacturing compared to traditional methods, including:
• reduction of time-to-market
• considerable material saving
• possibility to obtain a functional prototyping
PEEK printed with Roboze FFF 3D technology guarantees great advantages even in terms of processing time and realization costs. In the Oil&Gas sector, for example, the necessity of extracting raw materials in environments that are particularly hard to join because of high temperatures and the presence of very corrosive chemical agents, is parallel to the need of using equipment that are able to work in extreme conditions.
In this sector the use of super polymers like PEEK instead of metals, increases the lifetime of the components, thanks to the excellent chemical resistance and the absence of corrosion phenomena.
Use of PEEK: the challenge of Automotive and Motorsport sector
One of the greatest challenges in the Automotive and Motorsport sector is the reduction of weights with lighter parts, keeping the high performance standards of the produced components. Using super polymers like PEEK instead of light alloys, like aluminium, ensures high performance with a further reduction of weight.
The Automotive sector is always looking for new ways to reduce the CO2 emissions and increasing the fuel saving. The use of materials, able to respond in terms of resistance in the most extreme conditions, would allow to achieve these goals.
PEEK in the Aerospace industry
Even the aerospace industry is facing several challenges in the design of aircrafts that allow to reduce CO2 emissions, while ensuring high passengers’ safety. Over the next 20 years, it is estimated that the aerospace industry will need 35 thousand new airplanes, to be realized with production processes increasingly more efficient in terms of manufacturing costs and reduction of weight.
The use of materials like PEEK, combined with the FFF 3D printing technology, would allow to save up to 60% of the weight compared to metals.
