Study of 4D Printing Uses Grayscale to Create Reversible Shape Change in Photopolymers

Photopolymerization is a process that uses light to combine monomer molecules to create a polymer. It’s the basis of 3D printing, and in a dissertation called “Constitutive Modeling of Photopolymerization and its Application to 3D Printing,” Georgia Tech student Jiangtao Wu discusses the process in relation to both 3D and 4D printing. As Wu points […]

ETH Zurich Researchers Develop 4D Printed Load-Bearing Polymer Structures

There are numerous issues involved with transporting things into space, one being that some of them are just too big and bulky. One solution is to make those items small and capable of being folded up into compact packages which can then be expanded once the destination is reached. 4D printing is frequently used to […]

3D printing is amazing enough on its own, but when it becomes 4D printing, it’s even more incredible. The fourth dimension in 4D printing is time, and 4D printed items can change shape or self-assemble over time, with some kind of a stimulus. 4D print technology continues to become more advanced and complex, and researchers […]

Earwig Wings Inspire Researchers to 3D Print Multimaterial, Self-Folding Origami Elements

Many scientists have been inspired by wings, be they bat, bird, or butterfly, in their 3D printing research projects. A team of researchers from ETH Zurich and Purdue University have taken their inspiration from the wing structure of an earwig, a strange-looking creature with a fascinating wingspan. An open earwig wing can expand 10 times […]

Powerful New 4D Printer Speeds Next-Generation, Next-Dimension 3D Printing

3D printed objects that can move and change shape are technically 4D printed – the fourth dimension comes in the object’s ability to change shape when exposed to environmental stimuli like heat, humidity, and/or light, and then revert back to its original form. At this week’s National Meeting & Exposition of the American Chemical Society […]

LLNL Successfully Creates 4D Printed Flexible, Stretchable Composite Silicone Materials with Shape Memory

Earlier this summer, researchers from the Lawrence Livermore National Laboratory (LLNL) were working on using a direct ink writing (DIW) process to 3D print silicone metamaterials with shape memory behavior – which technically makes them 4D printed, as the fourth dimension is time in this instance. Now we’ve learned that, for the first time, the LLNL […]
