Case Study: Siemens Energy achieves up to 75% faster print times and 60% reduction in carbon fiber use with Markforged Simulation

Siemens - Customer Case Study

Siemens Energy’s Technology Application Center (TAC) needed faster, lower‑cost, structurally reliable fixtures and modular robot‑arm backpacks to support gas turbine vane hot‑air thermography and robotic inspection work. Traditional machined metal fixtures and molded gaskets were slow and expensive, and large 3D‑printed parts risked unwanted flexibility. Siemens turned to Markforged—using Markforged printers (Onyx One, Mark Two, X3, X7) and Simulation integrated into the Eiger workflow—to test, iterate and validate continuous fiber‑reinforced Onyx parts.

Markforged’s Simulation tool guided Siemens in applying appropriate boundary conditions, optimizing fiber placement and print orientation, which reduced continuous carbon fiber use by up to 60% and cut print times by as much as 75%. Measured savings include a vane fixture moving from a machined estimate of 48 hrs / $250 to a 3D‑printed Onyx+CF part at 18 hrs / $52.79, and robot‑backpack parts dropping to ~27–30 hrs and ~$77–$78 versus ~48 hrs and $150–$200 for machined equivalents—delivering faster iteration, lower cost and validated structural performance thanks to Markforged.
