Siemens implements an Additive Manufacturing Process Simulation solution to transform 3D printing
Global technology giant Siemens has announced its plans to implement new Additive Manufacturing (AM) Process Simulation solution to predict distortion during the 3D printing process. The product is fully integrated into Siemens' end-to-end Additive Manufacturing solution, which works to assist manufacturers in designing and printing useful parts at scale.
Building on Siemens' comprehensive digital innovation platform and the Simcenter portfolio, the AM Process Simulation solution uses a digital twin to simulate the build process prior to printing, anticipating distortion within the printing process and automatically generating the corrected geometry to compensate for these distortions. This simulation is paramount for constructing a 'first time right' print, and necessary for achieving the efficiencies required of a fully industrialised additive manufacturing process.
"Using the Simcenter 3D AM Process Simulation solution at toolcraft will allow us to complete our additive manufacturing workflow," explained Christoph Hauck, Managing Director, MBFZ toolcraft GmbH.
"Through real-world testing, we have gained confidence that the Siemens AM Process Simulation solution will assist us in ensuring quality output from our print process."
When metal parts are 3D printed, the method used to fuse the layers of the print typically involves heat. As the layers build up, the residual heat can cause parts to warp, causing structural issues within the part itself to print stoppage. Simulation of the printing process will therefore seek to resolve or alleviate many of these problems.

The new process simulation product will be integrated into the Powder Bed Fusion Process chain in the Siemens PLM Software Additive Manufacturing portfolio and is used to predict distortion for metal printing. The product provides a guided workflow to the user that allows for the assessment of distortions, the prediction of recoater collisions, prediction of areas of overheating, and other important feedback about the print process. With over 140,000 customers worldwide, Siemens PLM Software works with companies of all sizes to transform the way products and assets in operation are used and understood.
Through the AM Process Simulation solution, users are provided the ability to iterate on a solution between the design and build tray setup steps of the workflow, and the simulation step. This closed feedback loop is possible due to the tightly integrated nature of the Siemens digital innovation platform. The simulation data created feeds into the digital thread of information which informs each step of the printing process. This digital backbone enables the system to develop pre-compensated models and, more importantly, to feed those seamlessly back into the model design and manufacturing processes without additional data translation.
"This solution is the latest addition to our integrated additive manufacturing platform, which is helping customers industrialise additive manufacturing by designing and printing useful parts at scale," commented Jan Leuridan, Senior Vice President for Simulation and Test Solutions at Siemens PLM Software.
"By using a combination of empirical and computational methods we can increase the accuracy of the simulation process, feeding the digital twin and helping customers better predict their real-world print results. We have proven this over months of real-world testing with some selected first adopter companies. Providing corrected geometry and closed loop feedback can ultimately allow our customers to get better results from their additive manufacturing processes, helping to achieve that first-time-right print and realize innovation with this technology."
The AM Process Simulation solution is expected to be available in January 2019, as part of the latest NX software and Simcenter 3D software. For more information about producing quality parts with industrial additive manufacturing software.
Ultium Cells LLC/Li-Cycle: Sustainable Battery Manufacturing
Ultium Cells LLC - a joint venture between General Motors and LG Energy Solutions - has announced its latest collaboration with Li-Cycle. Joining forces the two have set ambitions to expand recycling in North America, recycling up to 100% of the scrap materials in battery cell manufacturing
What is Ultium Cells LLC?
Announcing their partnership in December 2019, General Motors (GM) and LG Energy Solutions established Ultium Cells LLC with a mission to “ensure excellence of Battery Cell Manufacturing through implementation of best practices from each company to contribute [to the] expansion of a Zero Emission propulsion on a global scale.”
Who is Li-Cycle?
Founded in 2016, Li-Cycle leverages innovative solutions to address emerging and urgent challenges around the world.
As the use of Lithium-ion rechargeable batteries in automotive, industrial energy storage, and consumer electronic applications rises, Li-Cycle believes that “the world needs improved technology and supply chain innovations to better recycle these batteries, while also meeting the rapidly growing demand for critical and scarce battery-grade materials.”
Why are Ultium Cells LLC and Li-Cycle join forces?
By joining forces to expand the recycling of scrap materials in battery cell manufacturing in North America, the new recycling process will allow Ultium Cells LLC to recycle cobalt, nickel, lithium, graphite, copper, manganese and aluminum.
“95% of these materials can be used in the production of new batteries or for adjacent industries,” says GM, who explains that the new hydrometallurgical process emits 30% less greenhouse gases (GHGs) than traditional processes, minimising the environmental impact. Use of this process will begin later in the year (2021).
"Our combined efforts with Ultium Cells will be instrumental in redirecting battery manufacturing scrap from landfills and returning a substantial amount of valuable battery-grade materials back into the battery supply chain. This partnership is a critical step forward in advancing our proven lithium-ion resource recovery technology as a more sustainable alternative to mining, " said Ajay Kochhar, President, CEO and co-founder of Li-Cycle.
"GM's zero-waste initiative aims to divert more than 90% of its manufacturing waste from landfills and incineration globally by 2025. Now, we're going to work closely with Ultium Cells and Li-Cycle to help the industry get even better use out of the materials,” added Ken Morris, Vice President of Electric and Autonomous Vehicles, GM.
Since 2013, GM has recycled or reused 100% of the battery packs it has received from customers, with most current GM EVs repaired with refurbished packs.
"We strive to make more with less waste and energy expended. This is a crucial step in improving the sustainability of our components and manufacturing processes,” concluded Thomas Gallagher, Chief Operating Officer, Ultium Cells LLC.
