Efficient production of high-strength lightweight components
The Fiber Patch Placement (FPP) systems developed by a Bavarian technology company constitute a step change in additive manufacturing. Thanks to high-performance robotics, the process has the potential to revolutionize the series production of geometrically complex lightweight parts in the automotive industry.
Weight reduction is a top priority in vehicle production. Safety equipment and luxury features have been pushing unladen weights up and up in recent years. In order to reduce fuel consumption and pollutant emissions, manufacturers are now endeavoring to reverse this trend. Lightweight construction is in great demand, yet the relevant materials and manufacturing processes will only find their way into the factories if they pass the test of cost efficiency.
Additive manufacturing Fiber Patch Placement (FPP)
The pioneering additive manufacturing process known as Fiber Patch Placement (FPP) constitutes a major breakthrough. FPP is a layering method in which a three-dimensional mold, positive or negative, is layered with carbon fiber strips, the so-called patches. The part is built up from individual adhesive fiber strips.
Just how fast, efficient and cost-effective Fiber Patch Placement can be in practice is already being shown by SAMBA Pro which has been developed by the Taufkirchen-based company Cevotec. This fully automated production line is equipped with two Stäubli robots. Between them, the ultra-nimble TP80 FAST picker and the six-axis TX200 bring a total of ten robot axes to bear on the free positioning of the patches.
And this is how Fiber Patch Placement works. Station 1 is where a continuous
