Metal binder jetting is an emerging additive manufacturing technology that has several key advantages over common powder bed fusion processes; high volumes of parts can be printed with minimal spacing; no support structures are needed, and larger lot sizes are possible. It has the potential to replace low-volume, high-cost metal injection moulding for everything from automotive and aircraft parts to medical applications. Because high resolution is possible, it could also reduce the cost and lead times for production of complex and lightweight metallic parts such as gears or turbine wheels.
Made available to existing Simufact Additive customers in August, the new tool extends its capabilities for MBJ processes. Manufacturers can predict the shrinkage caused by factors such as the thermal strain, friction, and gravity during sintering without specialist simulation knowledge. By compensating for these changes, parts can be 3D Printed as they are designed, and production teams can significantly reduce the proportion of parts that must be scrapped or re-processed. Sintering-induced mechanical stress is also predicted before print, indicating where defects might occur. Manufacturers can use this information to make changes earlier in their product development and reduce the need for costly redesign.
Designed for busy manufacturing professionals, the tool can automate the model setup, preparing the CAD or CAE file for manufacturing simulation and simulations can also be automated through Python scripts. To validate the sintering compensation and increase confidence in quality, the optimised geometry from the MBJ tool can be immediately compared to both the initial design (CAD) geometry and a metrology scan of a manufactured part within user interface.
"We are pleased to introduce the first solution for simulating metal binder jetting sintering process to the market so that manufacturers can take advantage of this important new method. We know customers see metal binder jetting as a pivotal technology for manufacturing, particularly where there's a need to need to produce intricate parts at high volumes like the automotive industry.
