Latest Patents

Hayakawa holds a patent for a method of additive manufacturing. This method involves a stress-controlled layer that includes both a compressive stress applied part and a compressive stress non-applied part. During the solidifying step, a laser beam or electron beam is scanned in different directions for these two parts. This unique approach allows the compressive stress applied part to expand further than the non-applied part or for the non-applied part to shrink compared to the applied part, based on the relationship between scanning direction and temperature changes.
