Exciting exhibits from ARBURGadditive – 20 years 3D printing showcase in Erfurt

• ARBURGadditive: Specialised range for industrial
3D printing
• Exhibits: Freeformer 750-3X and LiQ 5 3D printer process granulate and liquid silicone
• Good things come in threes: Congress, 3D printing exhibition and networking

Rapid.Tech in Erfurt has established itself as an important event in the 3D printing scene, and ARBURGadditive will be among those taking part in its 20th anniversary event from 14 to 16 May 2024. The company will be presenting two exciting exhibits: a large 750-3X Freeformer, which works on the basis of plastic granules, and an LiQ 5 for 3D printing liquid silicone (LSR). Visitors will find ARBURGadditive in Hall 2/2-215 at Rapid.Tech.

It is the triple combination of congress, exhibition and networking that makes this event special and interesting for the entire industry. As Dr Victor Roman, Managing Director of ARBURGadditive, explains: “Alongside the world’s leading trade fair Formnext in Frankfurt, Rapid.Tech is one of the most important German trade fairs in the field of additive manufacturing. It offers researchers and developers in particular a great platform for exchanging ideas.”

Focus on automotive, aviation and medical technology
The main areas of focus will be transport, aviation and medical technology, as well as software/AI and design for additive manufacturing and 3D-printed electronics. Commenting on the ARBURGadditive exhibits, Dr Victor Roman adds: “Demand for additively manufactured components for industrial applications is increasing and the requirements for part quality and material properties are becoming more stringent as a result. With our Freeformers and 3D printers from the TiQ and LiQ series, ARBURGadditive offers a suitable solution for practically every requirement.” The LiQ 5 3D printer will be demonstrating LAM (liquid additive manufacturing) technology for processing liquid silicone. This can be used to produce customised orthopaedic accessories and products for the food sector, for example.

Freeformer 750-3X – a very hot machine
With the large Freeformer 750-3X in the high-temperature version, the build chamber can be heated up to 200 degrees Celsius, with plasticising taking place at up to 450 degrees Celsius. This means that geometrically sophisticated ventilation ducts for the aerospace industry can be produced from Ultem 9085, for example. With its large build chamber (max. 330 mm x 230 mm x 230 mm), the Freeformer 750-3X also offers the option of additively manufacturing larger functional parts or small batches industrially – such as orthopaedic insoles up to shoe size 50. The possibility of additively manufacturing components from soft materials and high-temperature plastics or in hard/soft combinations is an impressive illustration of the machine’s wide range of applications. Short fibre-reinforced parts made of PA with 25 percent glass fibres and sealing components made of coloured LSR are other innovations that will be presented on the trade fair Freeformer in Erfurt.

The “comprehensive carefree package” from ARBURG
However, it is not only the premium-quality AM systems that make ARBURGadditive products so attractive to customers. The company also offers extensive and intensive training courses at the Arburg headquarters in Lossburg. Highly qualified application and service technicians also support customers on site with commissioning and trials as well as with material qualification in the form of a constantly growing material database.

“OPC UA delivers significant client process simplification”

Industry interview with Georg Kiesl, General Manager, Billion SAS

Mr. Kiesl, why is Billion working to promote the OPC UA standard in the USA?
For us, the biggest advantage is interoperability, which enables the use of different machine types, but also different brands of the same type within a factory’s digital network. This interoperability is a basic building block for many existing concepts, such as predictive maintenance – plus it is extremely important for future concepts. One single system for the entire factory, into which everything can be integrated, is a major advantage, and also the reason why we are strongly in favour of it.

That said, you and the other players in the plastics machinery industry will initially incur costs for your efforts. 
Yes, there are advance payments on our part, that are necessary to win our customers over. Networking machines with digital instruments as part of Industry 4.0 has been around for some time. Until now however, it has often been the case that everyone has tried to bring their own approaches closer to the customer. These are always individual implementations with individual communication protocols. By launching a standardised product, we can make it clear to customers that it will simplify their processes. It is true that OPC UA entails initial implementation efforts, but all subsequent steps are much simpler because the implementation logic remains the same. This means that the implementation costs for the second, third or fourth application are significantly lower.

The manufacturers of injection moulding machines have been working on the so-called Companion Specifications for a long time. What is the current status?
From our perspective, the basic framework has been established. There are basic Companion Specifications, plus we already have customers who are utilising them. At present, it’s a matter of expanding these specifications and adapting them to individual customer requirements, but because we have the basic concept, we can already demonstrate the benefits to customers. Our major French customer Schneider Electric is very much in favour of OPC UA. For example, they are looking to connect all the machines in their factories to their predictive maintenance tools, regardless of the machine type.

Are American customers more risk-averse? 
American customers know very well that sooner or later they will not be able to avoid networking their systems. However, some aspects there are different to Europe: the market in the US is very dynamic and open to new technologies. As a result, you see a lot of technologies come and go there. That’s why American customers are more cautious and don’t want to jump    on the first bandwagon that comes along. We have to convince customers that OPC UA will still be around in five, ten or even twenty years’ time. It’s a standard that makes a lot of sense, and that’s why it’s here to stay. There is an initial implementation effort, but that will decrease over time.

In other words, the system is able to grow with little effort.
Exactly, and even if new Companion Standards materialise that are perhaps not yet foreseeable, the server-client logic will always remain the same. If everyone uses their own individual Industry 4.0 approach, then the basic logic will be so diverse that someone who wants or needs to connect multiple brands and machine types to their network will have to start from scratch every time. With OPC UA standards, there is an initial hurdle for the implementation, after which everything is reusable: this is the main point for our American customers to consider.

How important is it for Billion that American customers accept OPC UA?
It is very important for us for two reasons: firstly, the USA is a huge sales market. On the other hand – and this is even more important for us at Billion – the USA is a significant economic trendsetter. The American influence is very strong in North, Central and South America – regions in which Billion has multiple operations. American thinking and American standards are widespread there, which is why it’s important to have the Americans on board with OPC UA. If you’re really looking to create a global language for machines, you can’t bypass the Americans.

SABIC Signs Memorandum of Understanding with Pashupati Group to Target Recycling Opportunities in India

The Ecosupply P Core Minimizes Paint And Rinsing Agent Losses

The new EcoSupply P Core is a modular paint   supply system based on pigging technology. This paint supply method   has already proved beneficial in the automotive painting world, but Dürr   has gone one step further and enhanced it for use in other industries for   the first time. The EcoSupply P Core is now adaptable wherever different   paint colors are applied in small quantities, such as in the construction, woodworking or automotive supplier industries. This system efficiently recovers unused paint, minimizing rinsing agent consumption and  speeding up color changes. Dürr will demonstrate how this works at the  PaintExpo from April 9-12 in Karlsruhe, Germany.  

The desire for a comprehensive color palette extends beyond the automotive industry. Customers use their color preferences as unique identifiers in other industries, whereas companies use distinctive colors as a unique selling point for themselves and their products. Manufacturers from the construction and plastic industries, for example, require a multitude of available shades to cater to their customers’ needs. However, each color change in the supply line results in paint and rinsing agent waste during the painting process. This can involve disproportionately high costs, particularly with very small quantities. This is because current paint supply systems clean the hoses using solvent and compressed air to remove all paint and rinsing residues left behind before preparation of the next color run can begin. This process is laborious and time-consuming, with longer and thicker hoses resulting in higher paint losses.

Pigging technology reduces paint consumption

For pigging technology, Dürr uses a fitting body tailored to the internal diameter of the hoses – the so-called pig – to make the process more efficient and reduce paint and rinsing agent consumption. The paint, flowing through the pigging hose, pushes the pig from the source to the destination module. This process removes any rinsing agent residue in the hose. Distributor stations, with the option of integrating up to four into one pigging line, provide the connection to the application technology. After the paint application, compressed air blows the pig back towards the source module. In the process, the paint left in the hose is transported back into the paint container. Rinsing agent then flows through the pigging hose towards the destination module. After cleaning, the process repeats.

Faster color changes and simplified maintenance

The EcoSupply P Core comes in single-pass and circulating versions and is suitable for applying both water and solvent-based paints. In both instances, reduced effort makes for faster color changes. Additionally, the modular design simplifies maintenance, allowing flexible configuration of individual components to adapt to user requirements and integrate into existing systems. Thus, the EcoSupply P Core can also integrate with other Dürr systems, such as the EcoSupply2 Core paint supply station.

Starter kit with everything you need

Dürr’s starter kit contains all important components, including a source and destination module, a distributor station for connecting to the application technology, hoses (which come in lengths of up to 100 meters), and the pig
itself. The starter kit also includes sensors for monitoring the pig position, maintenance and commissioning tools, and EcoDocu-technical documentation in digital format, complete with system examples.

Twenty-five years of experience in pigging technology

The EcoSupply P Core offers the manufacturing sector a cost-effective, easy-to- use paint supply solution for smaller quantities and applications in the low- pressure range. The new development is the culmination of Dürr’s 25 years of experience with the pigging technology featured in the EcoSupply P. Globally recognized, this tried-and-tested paint supply system with pigging technology has established its effectiveness in automotive painting. PaintExpo attendees can learn about the new EcoSupply P Core at Dürr’s stand 3320 in hall 3. The sales launch for the EcoSupply P Core is planned for early summer.
