How can additive process chains be automated and print quality monitored? How is a component made of metal and plastic created in multi-material printing? Scientists from Lower Saxony ADDITIV have been researching this and more in the past three years.

In this article, a method for automatic visual obstruction detection and mask-type congruent visual obstruction compensation, based on the principal of augmented reality, is presented. The method is based on the superposition of a simulated operator's field of view with information from a scene reconstructed by two RGB-Cameras. These cameras are arranged in a way that they can record the scene information behind the view restriction. Besides the presentation of the test rig, a detailed presentation of the image processing software is given. With a view to the later use of the system in a forklift truck, the real-time capability of the system will be tested and optimization possibilities will be discussed.

Within the project "CoMoGear - Condition Monitoring of Marine Gearboxes based on Wireless, Energy-Autonomous Sensor Nodes", an energy-autonomous, wireless sensor network was developed for condition diagnosis of highly stressed rotating components in marine gearboxes was developed. This allows intelligent, condition-based monitoring and maintenance, paving the way for unmanned shipping.

Due to their design, the lift mast and attachments on industrial trucks, among other things, can restrict the operator's field of vision. In the project "Virtual visibility improvement and intuitive interaction through augmented reality on industrial trucks (Visier)", this situation is to be counteracted with the development of a new driver assistance system. With the aid of augmented reality (AR) goggles, the aim is to create the conditions for the driver to be able to block out visual restrictions and thus take a look behind the cargo and the mast in order to detect hazards and obstacles at an early stage.

Within the CoMoGear project, an energy self-sufficient wireless sensor network for the condition monitoring of highly stressed rotating components in marine gearboxes was developed. This sensor network consists of several sensor nodes and energy harvesters.

Additive manufacturing - also known as 3D printing - includes manufacturing processes in which a component is usually built up layer by layer. This article describes the opportunities, hurdles and the current state of development of additive manufacturing.

By automating process steps, additive manufacturing can be integrated into industrial value chains. The Institut für Integrierte Produktion Hannover (IPH) gGmbH has been designing a process chain linking 3d printers and mounting stations automatically.
