    Real Time Control of additive manufacturing with IVS 70

    A new VINNOVA-funded project develops quality control and digital product storage for additive manufacturing. As a project partner, Unibap contributes expertise and technology in intelligent machine vision.

    Sepehr Hatami, researcher at Swerea IVF and project manager of the recently launched VINNOVA project.

    The project, led by Swerea IVF in Mölndal, aims to improve the additive manufacturing process using tools that become available through digitization. One of the goals is to implement quality control of 3D-printed details, and this is where Unibap’s IVS-70 is used.

    – We want to use Unibap’s technology to monitor the process, says Sepehr Hatami, researcher at Swerea IVF and project manager of the recently launched project. By comparing, layer by layer, high-resolution photos from IVS-70 with the CAD drawing which is used as a basis for printing, we can detect deviations and take corrective action. The intelligence built into the Unibap system is used to make the right decision.

    In additive manufacturing, a detail is printed with a 3D printer. The project uses a small SLM printer (Selective Laser Melting) of the brand SLM Solution 125HL, where a laser beam melts metallic powder to build up – layer by layer – a metal object. SLM is currently used to manufacture complex parts for, among others, the automotive, engineering, biochemical and aerospace industries.

    – It may take several days to print a metal detail, and it is a costly process also in terms of machine time and materials, says Fredrik Bruhn, CEO at Unibap. If something goes wrong, it is a great advantage to immediately be able to rectify or cancel printing.

    The companies involved in the research project include, apart from Unibap, AGA, GKN Aerospace, SKF and Höganäs. VINNOVA provides 50 percent of the project funding through “the smart digital factory” call for projects, and the participating parties provide the remaining 50 percent by in-kind contributions of time. The project will be completed by the end of 2018.

    – It is an exciting project where several prominent companies bring their knowledge and latest technology to help build up the new processes. By improving the quality of a future-oriented manufacturing method, we hope to help strengthen the competitiveness of Swedish industry, says Sepehr Hatami.
