About This Product
In addition to metal powder bed fusion bonding, AUTODESK Local Simulation can perform DED (directed energy deposition) simulations of powder feeding and wire feeding to simulate builds.
■DED – Directed Energy Deposition
Directed energy deposition method (DED) is a general metal additive manufacturing method. It is a method of melting metal by irradiating the metal powder material or filament with energy such as high-power laser light, electron beam, or plasma arc. This is an image of an application of so-called overlay welding.
Directed energy deposition is a modeling method that can be used not only for special materials such as stainless steel and nickel alloys.
■Why simulation is necessary
・Injector test
・Manufacturing cost – ¥594,000 Powder – ¥34,560 (5.82 kg) Post-process – ¥21,600 Plate resurfacing – ¥21,600
・Total modeling cost – ¥671,760 4 failures + 1 success total cost ¥3,358,800
■You can avoid the cost of 4 failures with a 15 minute simulation.
By running a simulation, you can understand what is happening during printing and take preventative measures. There is no need to spend material costs on modeling tests and confirmations, and you can check modeling trends in a short time.
Run simulations with different placements for the same shape. It is thought that when placed horizontally, the temperature change during modeling was greater, resulting in greater warping. It is thought that the vertical type, which had a small sintered area, experienced little temperature change, so no large strain occurred. The actual printing time is about 35 hours, but in the simulation, it was possible to judge the quality of printing in about 4 hours for vertical printing and 2 hours for horizontal printing, significantly reducing costs and wasted printing time due to printing failures.
