Researchers Use 3D Printing to Create Organoids for Drug Testing in Monitored Body-On-A-Chip System

Researchers Use 3D Printing to Create Organoids for Drug Testing in Monitored Body-On-A-Chip System

An organ-on-a-chip is a micro physiological system – a small cell culture chip that can mimic the structure and function of living human tissue. Organs-on-chips are helpful in terms of drug testing, and may one day even render animal testing non-essential, which would be great news. However, these small systems are not foolproof, and it’s just as […]

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

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 […]

Powerful X-Rays Put to Use in Study of Physics Behind Metal 3D Printing Process as Researchers Seek to Eliminate Structural Defects

Powerful X-Rays Put to Use in Study of Physics Behind Metal 3D Printing Process as Researchers Seek to Eliminate Structural Defects

From medical tools and aerospace turbines to components for race cars and satellites, it may seem like metal 3D printing can be used to magically make just about anything, for less money and weight. However, we know that the technology is not foolproof, and definitely not magic – issues like micro cracking and spattering abound, and […]

3D Data Shows What Makes the Heart Beat - in High-Resolution Detail

3D Data Shows What Makes the Heart Beat - in High-Resolution Detail

I’ve often read the phrase “my heart skipped a beat” in novels where it was used to describe a giddy, romantic feeling. I understand what authors are going for, but I can’t imagine that your heart actually skipping a beat, or having any kind of irregular rhythm, is a good thing; in fact, atrial fibrillation, […]

LLNL Researchers Use Direct Ink Writing to 3D Print Silicone Metamaterials with Shape Memory Behavior

A research team from Lawrence Livermore National Laboratory (LLNL) has used a direct ink writing (DIW) process to 3D print property-specific, silicone metamaterials that possess shape memory behavior, which technically makes them 4D printed. LLNL has worked with both 3D printed metamaterials and 4D printing before, but by using a DIW process, the material becomes more […]

3D Printing Inspires Artificial Blood Vessel Engineering Process in Teeth to Reimagine Root Canals

3D Printing Inspires Artificial Blood Vessel Engineering Process in Teeth to Reimagine Root Canals

Over the last few years, there has been a lot of research conducted on how to 3D print artificial blood vessels. In December, live 3D printed blood vessels were successfully implanted in Rhesus monkeys, and even more recently, researchers were able to get a 3D printed blood vessel network to survive and function within laboratory […]

MIT, Autodesk & Stratasys are Working With 'Secret' Materials to Develop New 4D Printing Applications

3D printing has come a long way since its inception in 1984. Today, we can print amazing things — from toys on home desktop 3D printers to replacement parts for hardware to advanced prostheses to living tissue. The array of materials available for printing is also widening, from standard plastic resins to chocolates to DNA. […]
