Twenty years of experience in the motorsport sector, taking Formula 1 and Moto GP teams to victory.

Spring Srl is the evolution of 3D printing service. The Italian company, which was established in 1998, has earned itself a reputation for its fast turnaround time and its technical and qualitative approach. As well as producing functional parts using the top additive manufacturing systems, it helps its clients optimise and re-engineer their components to guarantee maximum performance in minimum time.

Spring Srl has a reputation in Italy and overseas as a company that can take you to victory. It manufactures direct use parts, spare parts and low-volume production. It gives more flexibility to designers, engineers and technicians, dramatically cutting production time.

It has done ground-breaking work in 3D printing of soluble cores and equipment for carbon processing. “Soluble cores are made using thermoplastic materials such as ST-130 or ULTEM SUPPORT – explains Fabio Gualdo, co-owner of Spring Srl. – The newest alterative for hollow composite parts is FDM soluble cores. Composite is wrapped directly on a core that is dissolved away after the part has cured. This approach eliminates all tooling, which makes one-day delivery possible and design revisions practical.” Thanks to this particular production technique, the company is able to produce complex and highly precise geometries, something that would not be unthinkable using conventional technologies. “We recently produced a mould for carbon using a high-performance thermoplastic material. The geometry was complex, but our experience and hard work meant we were able to bring the project to a success conclusion” – explains Fabio Gualdo.

The company offers an extensive range of materials which includes technical thermoplastics such as ULTEM® 9085 and ULTEM 1010, which are used because of their outstanding strength, their heat resistance up to 220C° and the fact they are self-extinguishing. The company recently introduced PEKK, a new material it uses with its systems. This thermoplastic has extremely high chemical resistance, so is ideal for parts which come into contact with hydrocarbons, aggressive liquids or petrol.

“We are the first company in Europe to produce large monolithic parts (36 x 24 x 36 inches) in Nylon 12CF™ (carbon-filled thermoplastic) – continues Fabio Gualdo. – The material is comprised of a blend of Nylon 12 resin and chopped carbon fiber, at a loading of 35% by weight, which makes it one of the strongest and most flexible thermoplastic materials used in the world of additive manufacturing and one with the highest strength-to-weight ratio. Give its outstanding technical characteristics, it can be used in motorsport as a metal replacement”.

In the racing car sector, cutting production time is crucial and rely on the Spring Srl know how guarantees unbeatable lead times and quality. But this is not the only advantage: the service offers maximum design freedom, the possibility of producing highly complex geometries and a tangible reduction in costs compared to traditional technologies, without having to worry about the constraints of producing tooling and moulds.

“The leading companies we work with have understood the benefits of additive manufacturing – concludes Fabio Gualdo. – Thanks to our professionalism and know-how, we have accomplished things no one thought possible, the outstanding results to date are testimony of this.”
