A-line 4D printing system allows you to create one-dimensional objects that take shape under the influence of heat
The emergence of “4D printing” – Skylar Tibbits
Although technology creating objects that change shape on a 3D printer is not new, but when they can transform after penetration into a narrow hole, then open completely new application possibilities of this process.
Scientists from Carnegie Mellon University have presented the A-line technology, which makes it possible to create objects that are difficult to manufacture using three-dimensional printing (spring, tweezers). Their technique involves the creation of rods from polylactide, taking in advance «programmed» shape at an increase in temperature due to different distances between active and passive segments, their thickness and the direction of printing of each element in the structure.
The developed platform contains a library of eight bending directions, which can be combined for simple or complex geometry. She also includes a specialized design tool to simplify work user with system.
A temperature above 76 is required to start the conversion mechanism. ºC. The effect can be achieved by immersing the object in hot water, using a heat gun or steam. The main advantage is an initial convenience form that changes only in the right place and under special conditions.
By words developers, such rods can be use when creating poles for tents, chair frames or sculptures. By replacing polylactide with a biocompatible hydrogel sensitive to an electric field, they can will be apply in surgery.
Engineers have created a platform that will allow quantum computers to work at room temperature
