AITTIP releases the KRAKEN: a 4-in-one particular hybrid additive producing program


For the earlier three years, a European collective has been doing work on the KRAKEN – a hybrid subtractive and additive production certification system. The equipment is able of building objects up to 20 meters very long, applying 3 interchangeable 3D printing certification systems and a fourth subtractive device head. Accomplished at the conclude of September 2019, the KRAKEN has now been launched to the industrial market place.

“The equipment is completely ready for the industry, it has been tested in actual manufacturing setting and undertaking demonstrators have been validated by [collaborators] in serious circumstances,” announced José Antonio Dieste, researcher and KRAKEN Undertaking coordinator at Spain’s AITTIP Technological know-how Middle.

“We can now supply items or install Kraken cells in accordance to consumer demands.”

New degrees in hybrid manufacturing 

Active considering the fact that 2013, the KRAKEN Project was made attainable by funding from the European Union’s Horizon 2020 software. Throughout 8 countries in Europe, the venture provides alongside one another the skills of fifteen industry specialists and investigate institutes, like United kingdom engineering consultancy business TWI, Spanish civil infrastructure sustainability winner ACCIONA, Centro Ricerche FIAT (CRF) in Italy, and CECIMO, the European Affiliation of the Machine Resource Industries.

The objective of the challenge was to produce a machine able of generating 20-meter-extended components manufactured from aluminum, thermoset polymer components, and a mixture of the two. In the implementation of the equipment next the project’s achievements, the collaborative also aims to develop 150 new work opportunities in just associate firms, and 600 far more in the EU.

Additive and subtractive manufacturing in the KRAKEN

Now at completion, the KRAKEN system has interchangeable software heads for resin extrusion, wire arc additive manufacturing certification (WAAM), arc spray metallisation, and reducing/milling.

Resin extrusion on the KRAKEN is a committed method for depositing a polyurethane (PU) paste. The PU paste utilized in the system has been formulated by the KRAKEN collaborative and, with it, the process is capable of reaching a deposition rate of 120 kg/h. KRAKEN’s WAAM head, on the other hand, is tuned to 3D print aluminum at a level of up to 15kg/h. Arc spray metallization is integrated for the addition of metal coating or internet shapes on top of a polymer part, and the final, subtractive head of the KRAKEN targets 2mm cut depths at a velocity of 10m/min.

As a 4-in-one particular output machine, the KRAKEN efficiently decreases the quantity of floor place that would generally be needed for equipment possessing every single of these systems. It is developed for set up on the ceiling of a facility, and presently will work throughout a 20m x 8m x 6m footprint.

Validated with automotive and construction types

KRAKEN output is supported by a modified Pc Aided Production (CAM) application. Utilizing EDGECAM computer software as a base, the KRAKEN workforce additional new algorithms for hybrid production, such as planar horizontal layer additive approaches and immediate 3D freeform approaches. In-course of action monitoring, high-quality inspection and automobile-calibration is enabled by a stereoscopic scanner and digicam method with closed-loop regulate. To assist diminish knowledge limitations to the adoption for hybrid manufacturing and the KRAKEN equipment, the consortium has also made a detailed, absolutely free-to-use e-Understanding system.

Validation of the KRAKEN has been done through a amount of case scientific studies done for select associates inside of the consortium. CRF in specific created metal frames for the front and back of an Alfa Romeo 4C on the method. “Within KRAKEN,” the undertaking brochure states, “CRF demonstrated the great performances of equally polymeric and metallic products that are acceptable for automotive apps even for significant spot components.” In one more instance software, ACCIONA developed lining panels for tunnels with built-in electrical wiring and metal profiles. Obviously observing the probable of additive in development, ACCIONA has also collaborated in the past with the Institute for Innovative Architecture of Catalonia (IAAC) to generate a 3D printed bridge.
