Amsterdam Physicists 3D Print Ice Overhangs With No Supports, Using a Vacuum Instead of a Freezer
University of Amsterdam physicists print free-standing ice structures at room temperature by firing a 16-micrometer water jet into a 2 mbar vacuum, where evaporative cooling supercools it to freeze on contact, holding unsupported overhangs down to 14 degrees and melting cleanly to water when the pump switches off.

RMIT 3D Prints a Titanium Lattice That Floats — and Survives Two Weeks in Seawater
RMIT engineers 3D printed a foam-filled titanium lattice that floats despite being 70% stronger than equal-density steel or HDPE, and it barely degraded after two weeks in Port Phillip Bay.
