Strategies for metallic powder reuse in powder bed fusion: A …
6. Conclusion. Additive manufacturing is a growing field, and metal powder bed fusion is a popular subset of this new manufacturing class. Part of the advantage of additive manufacturing lies in its additive rather than subtractive nature, meaning that less material is wasted during the manufacturing process.

Direct Recycling of WC-Co Grinding Chip
II. Grinding: conduct an oil-free dry grinding using a centerless grinding machine with segmented wheels [16,62] to produce high-purity and fine (smaller than 60 mesh) chips. III. Post grinding: reduce the total internal oxygen content of the ground chips to avoid defective power, which in turn leads to a subsequent defective sintered product [68].
