Stratasys 3D printing slashes manufacturing costs of prototype moulds

Author / Editor: Melissa John / Barbara Schulz

France - French multinational, Schneider Electric, is epitomising the ‘Factory of the Future’ concept and has incorporated 3D printing technology across its manufacturing operations. This has seen the company slash the cost of producing injection mould inserts used for prototyping designs by up to 90%.

Streamlining manufacturing processes to achieve efficiency goals

With efficiency enhancement central to its value proposition and indeed the ethos of the company itself, Schneider Electric was keen to explore ways of streamlining certain manufacturing processes to achieve both short and longer-term efficiency goals. To help meet these objectives, the company has incorporated Stratasys 3D printing technology across its manufacturing operations in Grenoble, France, having originally used it for several years for prototyping new solutions.

Indeed, such is the widespread deployment of the technology that Schneider Electric now uses a combination of Stratasys Polyjet and FDM-based 3D printing solutions for product development, prototypes and industrialisation. This comprises multiple applications, including injection moulding and assembly-line tooling, the design and production of which is managed via the company’s internal model shop, Openlab. This extensive deployment of 3D printing technology also complements the company’s vision of creating the Factory of the Future.

The combination of dramatic financial savings and a greatly enhanced workflow achievable from incorporating Stratasys 3D printing into the process has contributed to the plant’s overall manufacturing efficiencies and reduced the time-to-market in key areas.

“This year, Schneider will launch around 400 new solutions, which is more than one a day,” says Sylvain Gire, vice president of GSC Transformation-Industrialisation at Schneider Electric. “Therefore, it is critical that we adopt technologies that help us reduce time-to-market.”

Efficient design and engineering of assembly-line tooling

One area in particular that underscores the efficiency benefits delivered by the company’s Stratasys 3D printing technology is the production of injection mould inserts used to print functional parts. This has seen the company slash the cost of producing injection mould inserts used for prototyping designs to just €100, compared to €1000 when manufacturing the same item in aluminium.

“We’re witnessing an astronomical cost-saving from 3D printing injection moulds, but we’ve also drastically cut the time taken to produce them, so we’re looking at a win-win every time,” explains Sylvain. “Manufacturing the prototype moulds in aluminium necessitates – in some cases – a lead time of as much as two months, but with Stratasys’ 3D printing solutions, the whole process is completed within a week,” he adds. “That’s a roughly 90% saving again, which would be unfathomable with any other technology.”

These benefits also extend to Schneider Electric’s mechanical design and engineering department, which is tasked with the production of assembly, control and adjustment tools for its diverse product range. Here, the company utilises a mix of both FDM-based materials (including thermoplastic polycarbonates) and PolyJet materials (such as the highly accurate Digital ABS) to produce prototype jigs and fixtures to validate the ergonomics and functionality of final assembly tools. Such tools span a range of items, including welding tool connectors, electromagnetic displacement controls and printed circuit board assembly connection tools.
