Revolutionary 3D Printed Ferroelectric Materials to Fight Harmful Bacteria in Medical Implants

Render of the printed material killing bacteria.

A team of researchers at the University of Arkansas has developed a new 3D printing technique to create ferroelectric materials that could help prevent harmful bacteria growth in medical implants.

Medical implants, such as pacemakers and artificial joints, can often become infected with bacteria, leading to complications and even implant failure. The researchers found that by 3D printing the ferroelectric materials onto the surface of the implant, they were able to create a surface that would repel bacteria.

Ferroelectric materials have unique properties that allow them to switch polarity when an electric field is applied. The researchers found that by 3D printing these materials onto an implant, they could create a surface that would alternate between positive and negative charges, which repels bacteria.

Scientists have developed a new method of 3D printing that allows them to print intricate designs into food, including a highly detailed cheesecake. The researchers from the Singapore University of Technology and Design created the technique by using a printer that simultaneously prints and cooks the food. The printer uses a heated nozzle to melt a mixture of cheese and cream, which is then layered to create the final product.

The researchers say the new method could have a range of applications, including creating personalized meals for people with dietary restrictions or swallowing difficulties. They also suggest that the technology could be used in high-end restaurants to create unique and artistic desserts.

Lead researcher Dr. Michinao Hashimoto said, “By using a 3D printer, consumers could order bespoke food designs, specifying not only the shape and size of their food but also its nutritional content.”

MIT 3D prints custom robotic heart replicas

The soft robotic models are patient-specific and could help clinicians zero in on the best implant for an individual.

MIT researchers have developed a new method for 3D printing custom, patient-specific replicas of a heart that could be used by surgeons to plan and practice complex procedures. The researchers used a flexible material that mimics the texture of real heart tissue and printed the replica using a multi-material inkjet 3D printing process.

According to Andrew Capulli, a postdoc at MIT’s Department of Mechanical Engineering, “surgeons often have to rely on their imagination to visualize a surgery from a 2D image, and it’s not always accurate.” The team’s goal was to create a replica that would allow surgeons to practice the surgery beforehand and get a better understanding of the procedure.

The replica is made from MRI data and printed with two different materials: a soft, flexible material that mimics heart tissue, and a hard material that provides structural support. Capulli says that “the materials and methods we used were important because we needed the replica to be flexible enough to mimic heart tissue but also strong enough not to deform during surgical manipulation.”

Drone Fleet Uses 3D Printing to Build Large-Scale Structures

Researchers at Imperial College in London have developed a 3D-printing system that uses multiple drones to build vertical structures while in flight. 

By Mark Crawford

Robotic additive manufacturing methods are being retooled for use in the construction industry. There are currently two ways to use 3D printing in construction: 3D-printing structural components off site, then transporting those pieces on site for assembly, or using ground-based 3D printers to produce structures on site. But ground-based printers are limited in the size of the structures they can print.

Researchers from Imperial College London and the Swiss Federal Laboratories of Materials Science and Technology have developed a system that eliminates this scalability issue by using fleets of drones equipped with 3D-printing systems. Large and complex structures could potentially be entirely built with multiple drone-based printing systems that operate from the construction site.

 
The research team, led by Mirko Kovac, a professor aerial robotics at Imperial College, calls the new process “Aerial Additive Manufacturing” (Aerial-AM), in which a fleet of drones collaborate in flight to create large, intricate structures. A multi-drone approach allows for autonomous 3D printing under human supervision and real-time assessment of printed geometry as construction progresses. Drones can also monitor and adjust their building capabilities on the fly in real time.

To make housing more affordable in the U.S., we need more of it. Millions of additional units, by most estimates.

This shortage of housing has a range of complex causes, but the high cost of construction — which rose even further thanks to pandemic-driven labor and supply constraints — is definitely not helping.

An idea from the tech world holds the potential to make the building process more efficient: 3D printing. Startups have been experimenting with the technology in large-scale construction, and now there’s a push to take it mainstream.

Marketplace’s Meghan McCarty Carino spoke with journalist Rachel Monroe, who took a deep dive into the topic in this week’s issue of The New Yorker.
