AI Technical Summary

Problems solved by technology

However, when using materials such as additive manufacturing that require additional processing (debinding and sintering to form the final part), conventional support strategies and techniques fail in many ways, such as support structures deforming or morphologically shrinking to fail to match The supported object, or the support structure is sintered with the supported object to form a single inseparable structure
