Important results from the project
The aim of CoHM-3D was to use 3D-printing to integrate fiber optic sensors (FBG sensors) into metallic components used in demanding environments, where today´s traditionally used techniques are not sufficient. Another focus of the project was to combine different digital solutions regarding data collection and data visualization from critical areas that had not previously been possible. The use of additive manufacturing opened up for the opportunity to optimize the products in terms of weight, design, functionality and in some cases to develop also unique material solutions.
Expected long term effects
FBG sensors were integrated into two different components, a hot-forming tool die and a part for land based gas turbines. In the case of the tool segment, approx. 10 sensors were integrated follwing a bending radius to monitor the temperature, and for the gas turbine part, approx. 30 sensors were integrated, also to monitor the temperature over a large area, unlike conventional approach with one sensor. 3D technology created the conditions for optimizing the products in terms of their functionality and some of the project partners are looking at how they can continue what has been developed in COHM-3D.
Approach and implementation
We worked with several different tracks at the same time, ranging from process optimization of 3D technology, cleaning of internal channels, simulation of products, fiber integration during printing, digital solutions for VR and AR and connection of the products as well as testing and verification. Furthermore, the results of the project have also been communicated with external partners in the form of external conferences, scientific and popular scientific journals. As a whole, the project has led to a new working method for how state measurement can be done effectively.
