A group of researchers from Singapore's Nanyang Technological University successfully created a 3D-printed flower using additive manufacturing that blossoms when exposed to a source of light.
The researchers set out to create a printed object that could respond to stimuli—and something other than just a change in temperature. The printed flower itself is made with a modified polyurethane material, which is able to remember its original shape. Since carbon black is also integrated into the material, the plastic object generates a slight amount of heat and causes the shape of the object to change in response to light or sun exposure.
This example of photoresponsive 4D printing, the process of printing objects that boast the ability to transform, sets a new precedent for artificial flowers and plants of the future.
