Besides eliminating a well-known issue of finished objects shrinking after printing, the lack of solvent also results in improved mechanical properties of the part while maintaining the ability to degrade in the body.

The team's graphic interface lets users design objects in a space that the robot has mapped out. The prototype, which the team built on a modified consumer vacuum robot, can add a range of objects to rooms.

As they don't require semiconductor materials, they represent a step toward 3D printing an entire active electronic device.

The method is faster and uses less material than other approaches.

The process is called holographic direct sound printing (HDSP). It builds on a method introduced in 2022 that described how sonochemical reactions in microscopic cavitations regions -- tiny bubbles -- create extremely high temperatures and pressure for trillionths of a second to harden resin into complex patterns. Now, by embedding the technique in acoustic holograms that contain cross-sectional images of a particular design, polymerization occurs much more quickly. It can create objects simultaneously rather than voxel-by-voxel.

The bricks could be reused many times over in building facades and internal walls. Thu, 19 Sep 2024 17:47:56 EDT https://www.sciencedaily.com/releases/2024/09/240919174756.htm
