To enable the human being to reach the Space, and sail the Oceans, teams of the aerospace and aeronautic industry need to work with high performance materials, last generation technologies and continuous innovation process, reducing  time and costs of production. This is possible also thanks to Additive manufacturing.

Spring srl, with 20 years of experience in 3D printing , is the ideal partner for these teams, infact, this entreprise guarantees certified process and high-performance materials. The Vicenza-based company has achieved the certification AS 9100:2016 for the production of prototypes and functional components for the aerospace sector. Process quality and know-how enable  Spring srl to produce functional components suitable for critical production environments.

Since the creation of 3D printing this technology provided only prototypes, but in the last 10 years the most innovative aerospace companies changed its use. Now additive manufacturing can produce functional components with materials such as ULTEM 9085, ULTEM 1010 and PEKK (ANTERO 800NA) to replace metals and composites.

ULTEM 9085, is a flame-retardant thermoplastic  V0 that with its FST (Flame, Smoke, Toxicity), Far 25.853 certification and chemical resistance is the best material for the aerospace sector. This thermoplastic is also extremely light, feature that enables weight reduction and fuel saving.

ULTEM 1010 is used for functional tests under extreme conditions, infact, it can withstand up to 216°C.

Spring srl has been the first company in Europe to produce parts in PEKK (ANTERO 800NA), the new thermoplastic of FDM technology (Fused Deposition Modeling).  This material is extremely resistant to high temperatures and chemical agents, for these reasons is suitable  for components exposed to hydrocarbons and  chemical fluids. Many spacecraft parts are realized in Pekk as equipment for shore-based support and to perform functional tests.

Spring srl owns the new professional 3D printing system: F900 certified AICS (Aircraft Interiors Certification Solution)  that provides the traceability of the production of components for the aerospace and aeronautic industry.

At present, Spring srl offers an extraordinary service of professional Additive manufacturing, producing monolithic parts by up 1 m 2.

The company is continuously evolving, putting the customer first and providing innovative solutions, qualitatively superior to those that are present in the market.

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.”
