5 Traditional decoration methods for complex designs Adhesive Film Application of adhesive film and overcoating with clearcoat Airbrush Build up design layer-by-layer with multiple working and drying steps Dot / Hexagon Stencil Process Build up design layer-by-layer with multiple working and drying steps Advantages All freedoms of design Disadvantages High material costs Durability at high erosion areas 5 Advantages Individual design with one paint system Disadvantages High lead time Repeatability of design Advantages Reproducibility of color gradations Disadvantages High recurrent costs (development & stencil production) Limited appearance and complexity

6 Traditional decoration methods for complex designs New Technology vs traditional methods - Traditional methods become insufficient with airlines desire for artistic designs Development of a new technology to create complex livery paintings automatically and increase flexibility 6

8 Direct Printing - technology Printer head is similar to an inkjet-printer CMYK* color spectrum * Cyan, Magenta, Yellow, Key (Black) Solvent ink instead of paint 3D-surface printing technology 8

9 Direct Printing - aerospace paint system integration Direct printing is applied directly on base colour The livery has to be covered by a qualified aircraft clear coat, which provides the necessary protection from external influences Layer thickness of printed film only 3 µm (average value) Total layer thickness of paint system up to 330 µm Current paint system Future paint system 9

10 Direct Printing - pilot device Direct printing device - Printing device is moved across the aircraft part by a gantry unit Cartesian automation system Line-by-line, from top to bottom 10

11 Direct Printing current technical application area Current technical application area ~600 11

12 Direct Printing - benefits Benefits - Full compatibilities to qualified paint systems All degrees of freedoms to create unique designs No extra adhesive film required to have high complexity design layouts 12

13 Direct Printing environmental improvements Environmental improvements - Extended lifetime due to less erosion effects Saving of resources Less weight due to minimum layer thicknesses Fuel savings Less consumptions of material VOC reduction 13
