Meagan Moore, a Biological and Agricultural Engineering student from Louisiana State University (LSU) has 3D printed a full-size model of the human body for use in radiotherapy.

Such models used in radiotherapy mimic the human tissue, and in medical terms are known as imaging phantoms or phantoms. They are used in radiotherapy to estimate the amount of dose delivery and distribution. A customized phantom of a patient can make the whole process more precise.

Engineers designed a new nanoscale 3D printing material that can be printed at a speed of 100 mm/s

Posted by in categories: 3D printing, drones, energy, nanotechnology, satellites

It’s all thanks to nanoclusters.

A new nanoscale 3D printing material developed by Stanford University engineers may provide superior structural protection for satellites, drones, and microelectronicsAn improved lightweight, a protective lattice that can absorb twice as much energy as previous materials of a similar density has been developed by engineers for nanoscale 3D printing.

According to the study led by Stanford University, a nanoscale 3D printing material, which creates structures that are a fraction of the width of a human hair, will enable to print of materials that are available for use, especially when printing at very small scales.

3D-printing microrobots with multiple component modules inside a microfluidic chip

Posted by in categories: 3D printing, biotech/medical, chemistry, nanotechnology, robotics/AI

Scientists from the Department of Mechanical Engineering at Osaka University introduced a method for manufacturing complex microrobots driven by chemical energy using in situ integration. By 3D-printing and assembling the mechanical structures and actuators of microrobots inside a microfluidic chip, the resulting microrobots were able to perform desired functions, like moving or grasping. This work may help realize the vision of microsurgery performed by autonomous robots.

As medical technology advances, increasingly complicated surgeries that were once considered impossible have become reality. However, we are still far away from a promised future in which microrobots coursing through a patient’s body can perform procedures, such as microsurgery or cancer cell elimination.

Uganda’s New Satellite Contains Equipment to 3D Print Human Tissue in Orbit

Posted by in categories: 3D printing, bioprinting, biotech/medical, food, security

With the help of NASA and Japan, Uganda has officially become a spacefaring nation — and its newly-launched PearlAfricaSat-1 craft has some pretty nifty tech onboard.

As the Uganda-based Nile Post reports, the satellite launched out of NASA’s Mid-Atlantic Regional Spaceport facility in Virginia on the morning of November 7 will not only provide important agricultural and security monitoring features for the developing nation, but will also conduct experiments involving the 3D printing of human tissue.

Per the Ugandan news site, the tissues printed on PearlAfricaSat-1 will be used in research into the effects microgravity has on ovary function — and as Quartz notes in its write-up of the NASA and Japan-supported mission, the microgravity aspect of the experiments is key because “bioprinting” human organs is difficult to achieve with Earth’s gravity.

Inside NASA’s most mind-blowing Mars base designs — including inflatable homes

Posted by in categories: 3D printing, space

THE most impressive designs for near-future Mars bases have finally been revealed.

These elaborate celestial plans are the difference between human life surviving on Mars – and thriving.

When it comes to planning how to live on a planet like Mars, 3D printing has provided scientists with the easiest way of navigating an environment that has similarities, but ultimately boasts a vastly different environment from Earth.

Water-Braiding Technology Invented For Next Generation Wireless Devices

Posted by in categories: 3D printing, mobile phones, nanotechnology

To produce the next generation of high-frequency antennae for 5G, 6G and other wireless devices, a team at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has invented the machine and manufacturing technique to manipulate microscopic objects using 3D printing and braid them into filaments a mere micrometre in diameter.

How small is this? One human hair varies in diameter between 20 and 200 micrometres from tip to root. Spider web silk can vary from 3 to 8 micrometres in diameter. So that’s teeny tiny. And for us to pack in the many antennae that go into mobile phone technology today, the smaller the better.

Engineering students have developed a 3D-printed prosthetic arm for people with disabilities

Posted by in categories: 3D printing, biotech/medical, cyborgs, engineering

More affordable than the regular ones.

The Arm2u biomedical engineering team from the Barcelona School of Industrial Engineering (ETSEIB) of the Universitat Politècnica de Catalunya designed and constructed a configurable transradial prosthesis that responds to the user’s nerve impulses using 3D printing technology.

Arm2u is a prosthesis that can replace a missing arm below the elbow. It can be controlled with myoelectric control, which means that it is controlled by the natural electrical signals produced by muscle contraction.

Is the future of solid-state batteries 3D-printed?

Posted by in categories: 3D printing, energy

The race to create a solid-state battery that could compete with today’s lithium-ion cells is heating up. In the past few years, there’s been a lot of R&D around solid electrolytes that promise to be safer and more powerful. In this video, we visit Sakuú, a company that doesn’t just want to make solid-state batteries, they also want to 3D-print them.

Compact and flexible fiber design ensures efficient focusing and razor-sharp images thanks to 3D printing

Posted by in categories: 3D printing, biotech/medical

An interdisciplinary team of researchers from Korea, Australia, Great Britain, and Germany—with participation of Leibniz Institute of Photonic Technology (Leibniz IPHT)—were able for the first time to optimize an optical glass fiber in such a way that light of different wavelengths can be focused extremely precisely. The level of accuracy is achieved by 3D nanoprinting of an optical lens applied to the end of the fiber.

This opens up new possibilities for applications in microscopy and endoscopy as well as in laser therapy and sensor technology. The researchers published their results in the journal Nature Communications.

Lenses at the end faces of optical fibers currently used in endoscopy for medical diagnostics have the disadvantage of chromatic aberration. This imaging error of optics, caused by the fact that light of different wavelengths, i.e., different spectral colors, is shaped and refracted differently, leads to a shift in the focal point and thus to blurring in imaging over a wide range of wavelengths. Achromatic lenses, which can minimize these optical aberrations, provide a remedy.
