We are proud to introduce you to the new Spring srl’s additive manufacturing service regarding the Multi jet Fusion technology, that will allow our clients to have thermoplastic components with the usual and high quality level guaranteed by Spring.

The combination between these elements is our daily challenge and today, even more, this is what we offer, thanks to new investments in terms of Know-how and production systems.

The new in-house arrival, as a result of an internal analysis, is the HP Multi Jet Fusion 5210 additive manufacturing system.

Multi Jet Fusion technology: how does it work?

Multi Jet Fusion (MJF) is a powder-based AM process that uses fusion energy and two agents; such are selectively jetted, with the fusing agent used to weld the particles that make up the finished part, while the detailing agent is used to define edges and details.

PA 12 thermoplastic of the Multi Jet Fusion technology

PA 12 is a thermoplastic used with the Multi Jet Fusion technology.

This material allows to produce structural, isotropic and watertight parts.

Companies intending to replace traditional production processes with innovative methods, such as Additive Manufacturing with FDM technology, are obtaining significant savings in terms of production time and costs; AM in fact allows them to gain an advantage over the competition.

Usually, when engineers need to produce a component with complex geometries, the process steps that are needed for its production can be several, such as milling, other CNC machining, welding etc.

The production of parts that need all these process steps requires utilization of huge economic resources and a long lead time.

A production tool, for the assembly of mechanical parts, printed with FDM technology.

The knowledge and skills in the use of FDM technology, industrial production systems and the use of high-performance materials allow you to have in a few hours light and resistant components, which can also replace metal parts.

FDM technology is particularly advantageous in the realization of small lots or single pieces with complex geometries.

Parts such as grippers, fittings and pallets for automated production lines, air ducts and distributors achieve the maximum benefits from production through the FDM process.

In the following example, we will present how the technical department of Spring srl, a 3D printing service specialized in FDM technology, has created a suction duct achieving 3 key objectives: lowering costs, reducing delivery time and producing a component with high mechanical performance.

 Air intake duct

Previously the duct was made of steel, thus requiring cutting the various sections, welding them and milling the ends to guarantee their geometry. The traditional process involved a considerable economic expenditure and the production times were particularly long.

Spring’s proposal made it possible to produce the monolithic part without joints and welds, thus significantly reducing production times and costs.

During the “Design for manufacturing” phase, the 3D model was optimized according to the FDM technology, inserting structural ribs at the ends of the component, to ensure greater resistance in fixing the coupling sleeves.

To fulfil the requests, Spring selected Nylon 12 CF for this project. Nylon 12 CF is a thermoplastic blend consisting of Nylon 12 and 35% carbon. This material offers very high values ​​of rigidity, resistance to impacts and to chemical agents. These characteristics make such material particularly suitable for metal replacement applications.

The final component that was re-engineered and produced by Spring Srl weighs 0.15 kg, compared to 1 kg of the previous solution, a weight saving of 85%.

Spring srl increases its productive capabilities in the medical and healthcare field, making materials available that are resistant, biocompatible and ISO 10993 certified, such as:

-ABS-M30i Acrilonitrile Butadiene Stirene: This thermoplastic is ideal for the production of medical, surgical and pharmaceutical tools. Components manufactured with this material are sterilizable through gamma rays, ethylene oxide (EtO) or hydrogen peroxide gas plasma and can be used in direct skin-contact applications.

-PC-ISO Medical Polycarbonate: This thermoplastic is used for the production of tools for doctors, surgeons and dentists. Pieces manufactured with this material are sterilizable through gamma rays or ethylene oxide (EtO). PC-ISO offers excellent mechanical features, an outstanding traction strength and a temperature resistance up to 133 °C.

ULTEM 1010 Polyetherimide: This thermoplastic is used for the production of medical applications and tools for food manufacturing (NSF 51). Parts produced with this material are sterilizable through gamma rays, ethylene oxide (EtO), hydrogen peroxide gas plasma or in autoclave. ULTEM 1010 is a self-extinguishing thermoplastic, that offers a notable mechanical resistance and high temperature strength, up to 216 °C.
