In a significant leap for additive manufacturing, Purdue University researchers have pioneered methods to add a ‘fourth dimension’ to traditional 3D printing by embedding sensors directly into printed materials. This advancement marks a critical step toward smart and bio-embedded materials that can sense, respond, and adapt to their environment. What Happened Purdue’s research team has … Read more
What Happened Recent advancements in 3D printing have paved the way for the emergence of 4D printing, a technology that incorporates time as the fourth dimension, enabling printed objects to change shape or properties after fabrication. A key enabler of this innovation is smart filament, materials embedded with responsive properties that react to external stimuli … Read more
What Happened Researchers have developed biobased cellulose-filled filaments designed specifically for 4D printing of humidity-responsive smart structures, as detailed in a recent publication by Mary Ann Liebert, Inc.. This work involves the codesign of filament material formulations and mesostructures to enable controlled shape changes in response to humidity, marking a significant step forward in smart … Read more
