Vanderbilt University strikes gold on 3D printed defects

Defects in 3D printed parts can cause tremendous failures in a finished component. Luckily, new research from Vanderbilt University, Tennessee, has gleaned a new way of detecting faults. By introducing gold nanoparticles into the 3D printer material, researchers can now quickly scan parts to help predict failures before they happen. “There are tremendous possibilities for […]

University of Nottingham investigates secret information storage using 3D printing

A new, 3D printable smart material developed at the University of Nottingham in the UK has presented researchers with a novel way of storing, and hiding, information. Laden with photochromic particles, the material changes color in reaction light, then turns back again when exposed to air. “In theory,” explains project co-lead Dr. Graham Newton, “it would […]

Dartmouth smart ink 3D prints, shrinks and transforms smart materials

A 3D printed, shrunken Arc de Triomphe represents the result of the latest research undertaken by the Ke Functional Materials Group at Dartmouth College. Focused on developing innovative materials for 3D and 4D printing applications, the Ke Group’s most recent ink makes objects that change size and color in reaction to external stimulus. Though still far from […]

Evonik material production capacity increases by 50% due to 3D printing demand

Evonik, the largest speciality chemicals company in the world, has opened a new Polyamide 12 (PA12) powder production plant to meet an increased demand for 3D printing materials and metal coatings.  The new Marl Chemical Park facility near Essen, Germany, will primarily produce Evonik’s VESTOSINT brand of PA12 powders, which is optimized for SLS 3D printing. […]

Is 3D printed bacteria the future of electronics?

Wearable tech is the name given to smart electronic devices that can be worn or implanted in the body. An enticing opportunity for innovative tech developers in sports, health, fashion and entertainment, 3D printing is revealing new possibilities for wearable tech such as electronic second skins, and smart fabrics. In the latest research from Massachusetts Institute […]

Rutgers 4D printing makes shapeshifting, drug delivering, soft robots

4D printing is method of 3D printing that allows an object to transform. In many cases, 4D printing has been used as a kind of “origami effect” where a flat, 3D printed net is tuned to fold into a three-dimensional object, such as a tulip. If scaled-up, the method could even make way for self-making flat […]

NIIST 3D prints wearable electronic textiles for remote response

A multidisciplinary research group led by Kuzhichalil Peethambharan Surendran at the National Institute for Interdisciplinary Science and Technology (NIIST), India, has released findings from a project making flexible electronics for use in remote locations. Combining additive manufacturing with screen printing, Dr. Surendran’s team is able to add antennas to polyester, opening up new potential for wireless […]

Study simplifies 4D printing process for self-assembling objects

A study published in Science Advances demonstrates a way of creating 3D printed shapes that assemble when exposed to heat. The study proposes a simplified process …

3D printed “dumbbell molecules” at Dartmouth College allow smart materials to perform heavy lifting

Researching ways to make smart materials capable of autonomous, and often sensory, behaviour The Ke Functional Materials Group at Dartmouth College in Hanover, New Hampshire, has …
