Penn State Researchers Make 3D Printing More Efficient with Five-Axis Fabrication

When you 3D print objects that have overhangs, supports are traditionally added to the print before the build begins, because the overhangs are not supported by anything below and your…

Through a Glass Clearly: 3D Printing Glass with Lasers and Clear Silica Resin

3D printing glass is a pretty tricky feat, mainly because it’s hard to maintain the material’s mechanical properties at its very high melting point. But a trio of researchers from…

Circular Economy Under-explored in 3D Printing, Say Researchers

Researchers from UNIDEMI at the Universidade NOVA de Lisboa in Portugal took note of the fact that, while 3D printing could serve as a key technology in a circular economy,…

Soft, Sensitive Robotic Gripping Fingers Made with Multi-material 3D Printing

Soft grippers enable robots to manipulate delicate objects, but this doesn’t necessarily mean that they’re safe to use around living organisms, such as elderly people, so researchers continue working to…

How Satisfying is Your 3D Printer? Researchers Improve Operator “Emotional Fusion” to 3D Printing Equipment

Researchers from the School of Mechanical Engineering at Shenyang University of Technology in China think that the emotional relationship between laser powder bed fusion (LPBF) 3D printers and their operators…

3D Printed Insoles Absorb Sweat to Power Electronics

Sweating is not really pleasant, but it’s a normal, natural way for the human body to regulate body temperature by decreasing thermal stress, which can occur for a number of…

3D Printing + Laser Cutting Opens Interesting Possibilities for 3D Printing Wood

If anything, 3D printing has been an inspiration for out-of-the-box thinking. The plethora of additive technologies out there have become a jumping off point for an entirely new landscape of…

New Process Directly Integrates Liquids into Materials During 3D Printing

If you thought 3D printing with hard materials, like plastic, could be hard, wait until you’ve tried 3D printing with liquids, which sounds like it’s even more difficult. A pair…

Natural Fiber Biocomposites in 3D & 4D Printing: A Review

In an article published in the journal of Materials & Design, titled “A review of 3D and 4D printing of natural fiber biocomposites,” researchers review the fascinating evolution of natural materials and…

Reality or Hype: 3D Printing Improving Performance in Sports Industry?

I’m not a big sports fan, but even I’m aware of the many possible 3D printing applications, from helmets and mouthguards to surfboards and shoes and so much more. But,…

Argonne National Lab Tests Weather Stations with Low-Cost Sensors and 3D Printed Components

For two years right out of college, I worked as an associate producer at a local CBS affiliate, and spent a lot of time learning the ins and outs of…

LLNL Researchers Bioprint Living Aneurysm and Watch it Heal Post-Op

Cerebral aneurysms, caused by the artery walls in the brain weakening, affect roughly one in every 50 people in the US, and are distinguished by a bulging blood vessel, which…

I-nteract Allows User to Design, Feel and 3D Print Objects in Mixed Reality

Due to their general ubiquity, it may not be readily apparent just how unintuitive computers are for the process of 3D computer aided design (CAD). A mouse or trackpad along…

Smallest 3D Printed Boat Yields Possibilities for Nanotechnology

We’ve seen some big 3D printed Benchy boats before, but I bet you’ve never seen one this small! A team of researchers from Leiden University in the Netherlands have published…

Researchers 3D Print Tunable Ferroelectric Metamaterials

Researchers from the University of Buffalo (UB) have developed a unique method for 3D printing ferroelectric materials, that is materials that can have their polarization switched through the use of…

US Army and Researchers 3D Print Microfluidic Channels on Curved Surface in an Open Lab

The field of microfluidics continues to grow as it’s used in a variety of applications: tissue engineering, drug screening and delivery, sensors, bioprinting, and more. Microfluidics involves manipulating and controlling…

UCSD Researchers 3D Print Shape-Shifting Liquid Crystal Elastomers

A team of materials science and engineering researchers from UC San Diego (UCSD) closely studied the qualities of liquid crystal elastomers, or LCEs, in order to figure out how to…

4-Axis 3D Printing Enables Tubular Implants with Controllable Mechanical Properties

Disease and other trauma can cause hollow, tubular human tissues, like the trachea, intestine, bone, and blood vessels, to be negatively affected by long-segmental defects. Autologous grafts can help fix…

3D Printing Silk to Make Scaffolds for Regenerative Medicine Research

Silk isn’t just used to make gorgeous, expensive clothing—this biocompatible, natural protein fiber is much stronger than it looks. The protein is made of 75% biocompatible fibroin, and 3D printed silk…

Self-Learning Robot Autonomously Moves Molecules, Setting Stage for Molecular 3D Printing

If you know even just a little bit about science, you probably already know that molecules are often referred to as “the building blocks of life.” Made of a group…

How Do 3D Printed Molds Stack Against Traditional Sand Casting Molds?

Aluminum alloys feature low density, as well as good corrosion resistance and mechanical properties, which is why casting them is an oft-used manufacturing technique. But, defects in molded parts is…

Microwave Electronic Circuits Made via Low-Cost 3D Printer & Plastic Filament

In the electronics industry, 3D printing has been used to fabricate sensors, stretchable electronics, and conformal electronics, and to make waveguide devices and antennas for microwave devices. That’s because the…
