A research team has found that island scanning, a printing scheme commonly used to prevent stresses from degrading or destroying 3D-printed metal parts, may not be a cure after all. Laser powder bed ...

Inexpensive 3D printers often have a problem called "warpage," in which objects printed by them tend to curl up as they harden. Now, however, scientists have harnessed the power of warpage to create ...

3D printing was first introduced in 1984 by Charles W. Hull. The inventor developed computer-aided software that designs and creates three-dimensional objects. After more than 30 years, 3D printing ...
