Table Held Up

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

If you’ve never heard of a tensegrity structure, you should stop now and watch the video below. In it, [The Action Lab] shows a 3D printed table that is held up only with strings. We didn’t say suspended by strings but held up. Or so it appears. The model is from Thingiverse, but it is one of those things you have to see to believe.

The basic idea is pretty simple. Strings have a lot of tensile strength but collapse under the slightest compressive force. The arrangement of strings puts the force on the center string which is essentially hanging — the force is pulling the string down. The other three strings aren’t just for show, though, they keep the structure from tipping over in any one direction.

Raspberry Pi Project Uses Artificial Intelligence to Detect License Plates

Posted by in categories: 3D printing, information science, internet, robotics/AI

When you’re a software and hardware engineer sometimes you need a little challenge. Engineer Robert Lucian Chiriac’s latest Raspberry Pi creation can detect license plates and read the characters with fairly decent accuracy. This is an involved project that relies on machine learning to properly interpret images from the camera into discernible text.

The primary license plate reading function is constructed using three separate applications (there are more used throughout the project, but these three are critical). Chiriac used the YOLOv3 object detection algorithm to create a bounding box around each license plate it detects from the camera input. The image within the bounding box is sent to CRAFT, a text detecting application. Once the location for each character in the plate has been identified, the information is passed along to CRNN to predict the actual text.

Chiriac mounted the Raspberry Pi, GPS module, 4G module and Pi camera to his car’s rear-view mirror with a 3D-printed unit he designed. The Pi camera is even adjustable with a ball-joint swivel mount.

There’s A Shortage Of Ventilators For Coronavirus Patients, So This International Group Invented An Open Source Alternative That’s Being Tested Next Week

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

Topline: A group of 300-plus engineers, designers, tech founders and others galvanized on Facebook with a goal of building a ventilator using readily available materials, 3D printing and open-source hardware resources. In just seven days, they built a prototype that will be validated as a solution to the global ventilator shortage by Irish authorities as early as next week.

Custom-Made Bones Are Being 3D Printed in a Lab Then Implanted in People

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

But using porous TCP to print bones does have some drawbacks. Its compressive strength is much lower than that of some human load-bearing bones, such as our thighbones. Compressive strength would rise over time, but it could be years before it would match pre-operation strength levels.

3D Printing Bones for Mars?

Several other groups are working on similar approaches. At NYU School of Medicine and NYU Langone Health, scientists have been developing 3D printed scaffold implants that could help patient groups such as children with skull deform ities. Early research results show that up to 77 percent of the bone scaffolding had been absorbed and replaced by natural bone 6 months after surgery, and that the newly-grown bone was just as strong as the original.
