Researchers at Saarland University in Germany have developed Hotflex, a computer-controlled, 3D printable composite structure that allows 3D printed objects to be precisely bent and deformed after printing. Consider the following statement about 3D printing: “After printing, the 3D object is static. You can no longer change it or adapt it to your needs.” Whether you agree with that statement or not probably depends on how you define “change.” After all, 3D printing does allow you to print an object, see how it functions, and then print a new version (or several new versions) if necessary.
