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.

Pekk (Antero 800NA) is the new material of additive manufacturing.  Let’s take a look to its benefits:

  • High chemical resistance

Pekk (Antero 800NA) is the most performing material of the FDM (Fused Deposition Modeling) technology, especially when it comes to chemical resistance. Indeed, Peek is the best choice not only for the aircraft industry but also for the Oil&Gas sector.  Moreover, this material has passed the military standard test MIL-STD-810G for chemical compatibility.

  • High temperature resistance

Pekk (Antero 800NA) has also an extraordinary resistance to high temperature, indeed, it withstands up to 150°C without any change to its characteristics. This exciting  feature has been designed for applications out of the cab or in engine compartments.

  • Customization and just-in-time production

Additionally, thanks to this new material is possible to realize customized and on-demand printing solutions. And as a result, companies can take advantage from storage cost savings and hence from a higher profitability.

  • No geometric limits – No material waste

Thanks to 3D printing  is possible to realize a never-before seen design. With traditional technology, manufacturers bought  Pekk as a semifinished (only available in limited shapes and sizes) and was processed by machines in clear and solid shapes. With traditional technology a big amount of material was wasted. Instead, with additive manufacturing not only is possible to realize complex shapes but also to cut waste.

Design is a core point for companies working in the consumer goods industry. And in the creative phase many models are built and tested , before putting a new product on the market. The success of this placement will largely depend on timing , ergonomics and look and feel of the product.

However, design process can be slow, inaccurate and companies can’t take these risks. That’s why manufacturers like Adidas are working with the additive skills to get top level prototypes in short time.

These new competencies empower Adidas designers to constantly refine its sports shoes. All sorts of design changes are reliable and efficient, thanks to 3D printed prototypes and model test.

Bigger benefits for companies come from additive skills rather than from traditional technology such as hand processing or peculiar tooling.

Especially, thanks to J750 experts, Adidas is getting :

  • High level of conformity: No more gap between the designer’s idea and the prototype. The 3D shoes drawing looks exactly like the 3D printed model in colors, shapes and textures.
  • Creativity freedom: This new printer is pushing the current boundaries of trial and production, indeed, now it is increasingly possible to get a multi-material model with complex geometries.
  • Incredible realism: The prototypes details are so great that the model seems ready to be worn.

At Spring srl a new 3D printing system is now available, its name is Stratasys J750.

This new printer, suitable for the PolyJet technology, offers a  multitude of benefits such as, for example, short building time for prototypes and tooling and high level of accuracy for functional components.

Through this technology it’s possible to work with a wide range of photopolymer materials from rigid resins, to rubber, from transparent materials to opaque ones. Thanks to this new extraordinary system a single model can be built with many different kinds of materials and related properties.

The PolyJet technology process  

Let’s now take a look to the major PolyJet processing steps in building a 3D model:

  • Firstly, a 3D CAD file is needed to get the printing parameters such as the photopolymers and support material placement.
  • Then, the printer settles tiny drops of photopolymers and at once polymerizes them with UV rays. As a result fine layers are collected one above the other on the tray, creating a detailed 3D model. The removable support material, with a gel-like consistency, is settled under geometric protrusions or complex shapes.
  • At the end of the process, the support material is manually removed by an operator. Now the 3D model is ready.

PolyJet technology  application fields and advantages

Polyjet technology is able to realize tiny walls and complex geometries with a wide range of materials and an excellent level of accuracy. This cutting edge technology is a fast, flexible and precise way to build prototypes with different colors and different degrees of hardness. There are a lot of sectors working with this technology: from the automotive manufacturers wanting to build aesthetic elements for the car, both inside and outside, to the packaging sector for the realization of mockup, consumer goods and industrial products.

The packaging and the consumer goods sectors enjoy the huge benefits of 3D printing.

Companies working in these fields need  lots of prototypes during the long and complex design process before putting a new product on the market.

Previously, those prototypes took a lot of time to be built, due to the use of traditional technologies, passing thought the production, finishing and assembly.

Currently, large companies like Adidas are leaving those old technologies to work with new production systems able to meet a wide range of needs.

Indeed Adidas is using  the additive manufacturing, especially the Polyjet technology, to realize sports shoes prototypes. Benefits are exciting.

But why bother using 3D printing?

There are many advantages in using 3D printing.

For example, let’s think about getting  finished prototypes in short time , reducing long production and tooling  process expected by traditional technologies, or about the lack of molds and equipment, or about the possibility of realizing prototypes with complex geometries.  Before there were indeed many geometric limits because of traditional technologies, but now with additive manufacturing is possible to meet the most demanding needs realizing any kind of object.

Unleash the power of imagination

The prototype look and feel must be as close as possible to the designer’s idea. However, with traditional technologies the gap between his idea and the finished prototype is huge. That’s why working with a skilled 3D printing service using ever more performing systems is the key.  The  J750 printer of the Polyjet technology has been embedded in the production site of Spring srl, and now it’s possible to:

  • Realize smooth, detailed and realistic prototypes
  • Produce molds and production tooling with an excellent accuracy
  • Embed the most wide range of colours and materials in one single model

The skills in using this printer allow to realize highly realistic models also thanks to the excellent colour and shape rendering, in this way designers can test what will be the realistic look and feel of the finished product.

Innovation is the key for the packaging and consumer goods sectors, for that reason it’s important to develop strategic alliances with an highly qualified company.

Spring srl is one of the top players in Additive manufacturing at an European level and is continuously working with the largest companies in these sectors. Spring srl after 20 years of experience in 3D printing is able to help these companies on their path of innovation.

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.”
