The Eiffel Tower recovering its shape using 4D Printing

4D printing

The Eiffel Tower recovering its shape using 4D Printing.Unlike 3D printing, 4D printed structures have the potential to transform shape in a pre-programmed way in response to a stimulus (e.g. changes in temperature). These types of structural transformations currently exist outside of additive manufacturing, with research having already demonstrated “shape memory” and “smart material” properties.

SLA Technology

SLA Technology Used for Shaping Memory Polymers for the First Time.While 3D printing is currently poised at the forefront of technology, 4D printing is nipping right at its heels. This next dimension in fabrication is really just 3D printing accentuated with the use of smart materials such as shape memory polymers (SMPs) that can be reformed into new shapes, and then counted on to revert back to their original shapes when an external stimulus, such as heat, is applied. (We’ve written a lot about 4D printing in the past, and you can find a quick, good overview here.) Continue reading “SLA Technology Used for Shaping Memory Polymers for the First Time (Video)”
