It seems like there are still a lot of challenges from the physics of printing liquid aluminum. To me this seems like it overcomplicated the task because they chose to print the aluminum, rather than just printing a form that can hold molten aluminum as a traditional casting might. Maybe that is already done though, this is academic work after all and not necessarily done to seek optimal solutions but to scope out future challenges.
- nullc 3y agoThere are useful shapes you cannot form through casting or subtractive manufacturing, such as shapes with complex cooling channels inside them or weight reducing voids.
