Different concepts were identified around the realms of KRAKEN in 2016, these correspond to both current challenges and solutions proposed in the project. The challenges are still relevant in 2019, and include shrinkage, residual stresses, warpage, part deformation, inability to sustainably deal with small series or ad-hoc production, horizontal shortcomings of AM across different markets, excess of inventory,excess of waste material, excess of needed workfloor space, too complex supply chains and others.
It is for this reason that the KRAKEN consortium has been working during 2016-2019 in the fields of hybrid manufacturing, control and CAM software, dissemination, exploitation and demonstration through a number of industrial examples.
KRAKEN's objectives were to merge the MEGAROB subtractive machine (working area 20x6x3 metres) together with high efficient metallic (10 kg/h deposition rate) and novel non-metallic (180kg/h deposition rate) additive technologies. KRAKEN aimed at developing a hybrid manufacturing machine to equip industry with an all-in-one affordable machine for the customised design, production/repair and quality control of functional parts (made in aluminium, thermoset or both materials combined) from 0,1m to 20m through subtractive and novel additive technologies. KRAKEN also aimed at being able to produce and repair functional parts with dimensional tolerances under 0.3 millimetres and surface roughness under Ra 0,1 μm.
The KRAKEN consortium, coordinated by AITIIP, is integrated by 15 partners from 8 different countries. The project lasts 36 months and has a budget of 5.9M€, 30% of which is allocated to SMEs. Other partners who participate are Acciona (Spain), Planit and Vero UK Software (United Kingdom), Leica Geosystems (Switzerland), CSEM (Switzerland), Pininfarina (Italy), Vision Business Consultants (Greece), Autonomous Systems (Romania), Centro Richerche FIAT (Italy), Cecimo (Belgium), Espace 2001 SA (Luxembourg), Alchemie Ltd (United Kingdom), Arasol (Spain), TWI (United Kingdom) and Teamnet World Professional Services (Romania).
At M36, KRAKEN has progressed and ended satisfactorily and its key objectives – sustaining the expected impact – have remained strong, achieved and relevant. There is still room for progress and improvements in the future, mainly in the development of new resin materials and further automation of the processes.
