Nowadays, thanks to the knowledge and expertise in state-of-the-art additive manufacturing technologies like fused deposition modelling (FDM), manufacturers can develop high-performance solutions.

One outstanding example is Genesis Systems Group, specialist manufacturer of robotic systems for welding and water-jet cutting.

The company needed to develop more high-performance positioning systems, so the technical staff decided to revolutionise their conventional approach to building components and try out the FDM process, using ULTEM 9085 to create their complex monolithic parts.

It was a success, bringing together the elements which help them reach their set project targets. These elements are:

·       Professional additive manufacturing systems

·       High-performance materials

·       Knowledge of the FDM technology

In the past, the company used to build their metal parts using conventional technologies and lead time was about 20 days. Today, thanks to the new solutions offered by additive manufacturing, parts are ready after only 3 days, with an 85% reduction in time and 94% in costs.

Another benefit of this new engineering approach is that it significantly reduces the weight of the finished component, now weighing only 1 kg compared to 15 kg.

SPRING Srl for production excellence

Spring Srl has been using additive manufacturing technologies for 20 years and its technical staff is the driving force behind the company. The technical skills which Spring brings to the table mean it can co-design components with its clients to deliver the best possible technological solutions.

Over the next couple of years, passenger traffic will grow exponentially, forcing airlines to order thousands of new aircraft.

Major investments will be made primarily in innovating interiors. The solutions will not only offer passengers a positive flight experience but will also meet construction standards in terms of sturdiness, cost-effectiveness and reduced weight.

Interiors: the main areas of development
Peacock Suites by Paperclip Design can be transformed from a suite with two bedrooms into a family room with bunkbeds.

Redesigning interiors will lead to the creation of new modules for cabins, seating, onboard kitchens and bathrooms. The innovations will also include the air conditioning, electric, electronic cabin management, drinking water and waste systems.

Another interesting area of development is the in-flight entertainment and connectivity market. This sector includes software and design aimed at entertaining passengers as they travel.

The “windows” in the centre suites of the Emirates’ B777-300ERs are actually displays.
The dawn of a new age

Unlike other sectors, such as the consumer electronics market, whose regulations are less stringent, the aerospace industry is rather conservative. However, we are at the dawn of a new age which is witnessing widespread implementation of innovative technologies.

According to Airbus, amongst others, 3D printing will have a revolutionary effect on the sector. So, it is no surprise to learn that the company has introduced more than 2,700 3D-printed plastic parts in its A350 XWB.

3D printing with FDM technology

FDM technology is a 3D printing process. Thermoplastic material is heated and goes from a solid to a semi-liquid state, enabling adjacent layers to be welded together. The FDM technology used by Spring S.r.l gives a significant reduction in time, weight and costs compared to producing the same parts using more conventional methods. Furthermore, 3D printing can produce highly complex geometries. This technology opens up a new world of possibilities, meaning engineers can completely rethink every single object. These important benefits have caught the attention of the aerospace industry.

Spring S.r.l: the number one partner for the aerospace industry

Companies can benefit from the wealth of knowledge, know-how and expertise Spring S.r.l has built up in over 20 years in the additive manufacturing business. The level of excellence achieved by Spring in manufacturing parts for the aerospace industry has led to the company being awarded AS9100:2016 certification, designed to meet the strict requirements of the sector.

For more than 20 years, prototyping and high-end production have been our core business. We use the latest cutting-edge 3D printing technologies (Additive Manufacturing).

3D printing is revolutionising product development in the fashion industry, and five aspects are the main focus of its interest:

1 – Product personalisation

2 – Prototyping

3 – Experimentation

4 – Production efficiency

5 – Cutting lead time

Product personalisation is the main objective of many companies, ranging from accessory to clothing manufacturers.

3D printing, which takes personalisation to the next level, is being used more and more to create products tailored to consumer tastes.

“We offer designers an extremely high degree of personalisation. There are hundreds of thousands of colour combinations we can experiment with on shoes, bags and eyewear. Innovative materials allow us to come up with new accessories. We invest our resources in expertise and this enables us to deliver consistently high results.” – Fabio Gualdo, owner.

The company has acquired a new production system called Stratasys J750. It enables highly qualified personnel to produce prototypes and products in multiple colours and materials.

“As a frontrunner in design and fashion, it’s no surprise that Italy is one of the leading adopters of the J750. The ability to produce ultra-realistic parts that match Pantone color standards and in a range of materials like no other, makes the J750 the only 3D printing technology that can truly deliver the needs of these industries. Spring is a testament to this – incredibly, buying its thirteenth 3D printer from us. With its impressive expertise in optimizing the use of additive manufacturing, we’re excited to see how Spring continues to push the boundaries of the technology with this latest addition.” – Giuseppe Cilia, Area Sales Manager, Stratasys.

Technological revolution

Being able to print multi-colour and multi-material objects is a recent accomplishment. Aesthetic prototyping was limited in what it could achieve and 3D models could only be produced in one colour or material. This was holding back innovation in the fashion world. The advances in additive manufacturing and the Stratasys J750 printer now enable Spring, one of the leading companies in the field in Europe, to produce multi-colour and multi-material prototypes. This is a milestone for the sector.

3D printing or additive manufacturing is a production process based on deposition of material layers to make three-dimensional objects.

This process is different from a more traditional one in which objects are produced by material removal from a starting block. Additive manufacturing is not suitable for mass production, indeed, 3D-printing is very competitive when it comes to produce prototypes in small batches or singles pieces for aesthetic and functional assessments or for making  end-use parts.

A 3D-printing company or an additive manufacturing company is a production center that is specialised on this manufacturing process.

There are different 3D-printing technologies, classified according to layers printing process, and among these the most spread is FDM (Fused Deposition modeling) technology.

Some of the main benefits coming from a partnership with a 3D-printing company are:

  • Design freedom: 3D-printing experts are able to produce any kind of geometry also the most complex one.
  • More lightness : The FDM-technology materials are thermoplastics that can reduce the product weight, especially when it comes to metal replacement.

Further benefits come from FDM-technology materials, to find out more click here!

3D printing: useful applications for automotive field

3D-printing experts can provide you with:

  • Pre-series molds: Design is key for automakers. Companies need many iterations of design (from 50 to 200 prototypes) before finding the perfect one. For example, let’s think about matrices, our experts can help you to test the best ones, saving time and costs.
  • Customization: More and more customers choose a car as a means of expressing themselves. Our skilled experts can produce for your company custom parts for car interiors and exteriors: custom panels, compartments, dashboards, GPS, satellite navigation systems and more.
  • Components for tests: Thanks to additive manufacturing services, automakers can do different kinds of tests, such as, for example functional tests: tests drive, engine tests, fit and form testing and more.

Prototypes are key for companies when it comes to design and realize new products. A company specialized in additive manufacturing optimizes production process, drastically reduces the Time to Market and provides the best mockups, samplings and short batches.

Spring srl owns a new Polyjet 3D printer that opens up new horizons for prototyping: so let us show you how this new machinery works, what its benefits are, its application fields and materials.

How does the Polyjet technology work?

Polyjet is a 3D printing technology with which it is possible to realize multi-color, multi-material prototypes and equipment. More than 360.000 colors are available with this machinery and it is also possible to print with realistic textures.

A 3D Polyjet technology uses a printing process similar to that in the 2D printer. However, a 3D Polyjet printer doesn’t work with ink drops but it deposits on a tray liquid-photopolymer layers and then it dries them with UV rays.

To realize a 3D model the printer deposits layers one by one. As the drying  process is finished, models are ready to be used.

What are the main application fields of the Polyjet technology?

The Polyjet benefits are the highest print quality and accuracy, a wide range of materials and the possibility to print with realistic textures. This printer enables to realize smooth surfaces and very thin walls.

Below you can find the main application fields of the Polyjet technology:

  • Highly realistic and multi-material prototypes. No more limits for designers that can work with very realistic prototypes, thanks to the possibility of mixing more materials in the same 3D model, realizing  transparent components and combining more than 360.000 colors.  Designers and developers can get prototypes and realistic models with multi-color elements, labels, realistic textures in a single operation, before sending them to mass production.

  • Aesthetic components with precise and smooth surfaces. 0,032 mm layers enable to realize prototypes and aesthetic parts with very smooth surfaces.  The level of detail is around 0.1-0.3 mm and it also depends on the geometry, on the size and the object orientation.
  • Master molds for overmolding. With J750 it is possible to realize, in low-volume, technical- rubber matrices for overmolding. The polyjet process is faster and less expensive  than more traditional methods that produce metal master molds.

  • Components for medical industry and dental labs. Multi-color and flexible materials enable to realize realistic anatomical models. These models are used in doctor training and surgery prep, cutting costs of surgery room and improving patient care solutions.

What are the materials of the Polyjet technology?

  • Vero family. The vero family materials are ideal for fit and form testing, for moving and assembled parts, concept and exhibition models. Unleash your creativity, we will provide you with the brighter colors.
  • Simulated Polypropylene. These materials simulate the appearance and functionality of polypropylene. These materials are ideal for prototyping containers and packaging, flexible snap-fit applications and living hinges, toys, battery cases, laboratory equipment, loudspeakers and automotive components.
  • Rubber-like. It offers various level of elastomer characteristics. It combines rigid materials for a variety of shore A values, from Shore A 27 to shore A 95. It is ideal for rubber surrounds and overmolding, soft-touch coatings and nonslip surfaces, knobs, grips, pulls, handles, gaskets, seals, hoses, footwear, and exhibition and communication models.
  • Digital ABS. These materials simulate ABS plastics by combining strength with high temperature resistance. Ideal for functional prototypes, snap-fit parts for high or low temperature usage, electrical parts, castings, mobile telephone casings and engine parts and covers.
  • High temperature : The only material with extraordinary thermal characteristics is RG525. Ideal for form, fit and thermal functional testing, high-definition models requiring excellent surface quality, exhibition models that endure strong lighting conditions, taps, pipes and household appliances, hot air and hot water testing.
