HP Multi Jet Fusion technology is a relatively new 3D printing technology, offering breakthrough speed and quality, with a significant reduction in manufacturing costs compared to other additive technologies. It can complement and improve production processes based on CNC machining, allowing greater design freedom and weight reduction. It allows the use of complex geometries, which is not possible in CNC machining, 3D printing lighter parts than those made of aluminum or steel, while maintaining optimal mechanical properties.
Thanks to the use of HP MJF, the French company Aereco, which develops innovative ventilation solutions in residential and office buildings, can design prototypes, avoiding costly investments in metal molds required for injection molding, which they previously used in the production of e.g. fan wall brackets. Aereco solutions are based on modulating the air flow rate to achieve the highest energy efficiency and indoor air quality.
The company wanted to match the wall mount to the air extraction for a specific customer, which is why it modified both its design and branding, adding a company logo.
The first tests with new production technology – HP MJF 3D began at Aereco two years ago and concerned only selected plants, and then gradually spread to all company departments responsible for prototyping and production. Currently, Aereco in HP MJF technology produces about 150 different elements: instruments, tool assemblies and end parts, reducing their time to market.
The choice of HP MJF was due to the fact that other available technologies, such as FDM, SLA and SLS, did not offer such precision and durability of the produced components. Pierre Kraus, head of Aereco’s laboratory said:
Our employees were surprised by the scale of the technology’s capabilities, as well as the quality and reliability of HP 3D HR PA 12, which exceeded all their expectations compared to other technologies tested.
The Special Machines team, which is one of the main users of HP MJF technology at Aereco, has radically changed the way we work, design and even come up with new solutions. More and more custom solutions began to be created, using 3D printing as the main production method. Nicolas Muris, project manager at Aereco adds:
Thanks to HP MJF technology and high quality plastic parts supplied, we are able to produce light and versatile components that would otherwise be made of metal using decreasing (subtractive) technologies, which would result in higher costs, longer production times and less ergonomic solutions.
The introduction of HP Multi Jet Fusion technology, according to Nicolas Muris, helped the Aereco team not only easier and faster to create prototypes, but also the product concept itself – without restrictions due to the method of production.
At the same time, the company has made significant savings in tooling and instrumentation, which cost € 3,000 in traditional processes involving aluminum and stainless steel, and € 300 in HP MJF, which means a cost reduction of 90%.
HP3D.pl, offering entrepreneurs in Poland the opportunity to implement HP MJF technology, draws attention to the fact that the use of this 3D printing method in production processes based so far on CNC machining allows to reduce production costs, eliminate downtime and speed up the assembly of complex elements. Initial investments, which are high in traditional production methods, using HP MJF technology can be significantly reduced, which will enable companies from the SME to provide tailor-made products or services tailored to the needs of Industry 4.0.
