FORMNEXT 2016 DAY 4 _ What is news in software for Additive Manufacturing?

Day four of FORMNEXT 2016, the catch-up of Additive Manufacturing & 3D-printing industry


AUTODESK

Alexander Oster (Director Additive Manufacturing at AUTODESK) talking about Generative Design and the AIRBUS Partitioning- project


AUTODESK has invested heavily in AM over the last years. Alexander Oster (Director for Additive Manufacturing at AUTODESK) explained in his presentation on the TCT-Stage how AUTODESK has strategically invested in additive manufacturing since 2008. The acquisition of NETFAB and WITHIN TECHNOLOGIES, two key players in AM software, but also the earlier acquisitions like Moldflow fit nicely into the portfolio. More recently Autodesk invested in hardware companies like FIT TECHNOLOGY GROUP, OPTOMEC, Carbon3D and XJET to drive Additive Manufacturing.

Process Simulation software

They idea of process simulation is not new at all, looking at injection molding or laser welding industry which have been using simulation for years and years. But more and more vendors are taking on this technology to improve geometric accuracy of additively manufactured metal parts. High-temperature gradients in the laser based powder bed fusion process (SLM / DMLS)  are leading to residual stress. Temperature gradients over the build height are leading to further deformations of the parts. After a heat treatment for stress-relief, the parts simply deform. Simulating this distortion enables to digitally invert the deformation on the nominal models. So the parts are built on purpose deformed, allowing them to bend back into the shape of the nominal model during the annealing. Further, build-up orientation of parts can be optimised. Looking at components which can take up to hundreds of hours to be built and parts which have to be first-time-right, this software solutions can mitigate risks and ensure higher part quality. It will be interesting to see when these tools will fit seamlessly into the data preparation process.


“Software is the key”

Watch this interview with Sean Keith, Machine Technology Integration Leader at GE Additive was recorded at FORMNEXT. Sean is pointing out how important the software is for the future of Additive Manufacturing. Interview link: youtu.be/ecnbb2XUwbM
