Desktop CT and 3D Scanner With Arduino

jbumstead

Computed tomography (CT) or computed axial tomography (CAT) is most often associated with imaging the body because it enables clinicians to see the anatomical structure inside the patient without having to do any surgery. To image inside the human body, a CT scanner requires X-rays because the radiation has to be able to penetrate through the body. If the object is semi-transparent, it is actually possible to conduct CT scanning using visible light! The technique is called optical CT, which is different than the more popular optical imaging technique known as optical coherence tomography.
To acquire 3D scans of semi-transparent objects, I constructed an optical CT scanner using an Arduino Nano and Nikon dSLR. Halfway through the project, I realized that photogrammetry, another 3D scanning technique, requires much of the same hardware as an optical CT scanner. In this instructable, I will go over the system I constructed that is capable of CT scanning and photogrammetry. After acquiring images, I have steps on using PhotoScan or Matlab for computing 3D reconstructions.

FlashForge Targets Education With Inventor 3D Printer LineTyler Koslow 

FlashForge has unveiled their latest 3D printer line. It includes the Inventor, a desktop printer geared towards educational use.

Like many other Chinese 3D printer manufacturers, FlashForge has thrived by balancing its efforts between affordability and performance. At the recently held Inside 3D Printing New York conference, the company was on the scene with their latest product line.

The new Inventor series is comprised of two different desktop 3D printers, both of which seem exceptionally intuitive. The Inventor is engineered for the educational sector, while the “II” 

model is said to operate with the intuitiveness of a smartphone

...

The build volume of this printer is 230 x 150 x 160 mm, and even includes dual extrusion via a MK9 extruder head. This allows for multi-color prints, as well as use of soluble support structures. It’s compatible with PLA, PVA, ABS, HIPS, and other speciality materials.

This new printer is also equipped with a heated build plate, while offering 0.1 to 0.4 mm layer thickness.

Single Cylinder Air Engine

gzumwalt 

Before starting with this Instructable, I would like to express my sincere thanks to Instructables for featuring Single Cylinder Air Engine. I am indeed honored and humbled, again, many thanks.

Single Cylinder Air Engine runs on compressed air, a vacuum cleaner, a balloon, or even lung power. I've included three adapters in the design to interface with each. Please note the friction test video; your engine needs to pass this test before being successfully operated on balloon power.

The design incorporates two ports, one upper and one lower. When Single Cylinder Air Engine is viewed from the port side, "Wheel Piston.stl" rotates clockwise when pressure is applied to the upper port, and counter clockwise when a vacuum is applied to the upper port. As pressure or vacuum is applied to the upper port, the lower port functions as an exhaust (when pressure is applied) or an intake (when vacuum is applied). The opposite occurs when the lower port is used for pressure or vacuum.

MakerBot says its new print process reduces times and costs by around 30 percent

Brian Heater  

MakerBot’s MinFill arrived quietly last night as a firmware upgrade for existing customers, and the company is already calling it a “big benchmark in speed and widespread adoption of 3D printing.” Many are understandably a bit cautious around such grandiose proclamations from players in this space, particularly when it comes to something as unabashedly unsexy as infill — the support structures inside a model that keep it from collapsing.

At a bare minimum, however, the newly released MinFill setting boasts some potentially impressive numbers. The technology, designed in-house for the company’s Print software, runs an algorithm that determines the minimal amount of material required to create sufficient infill for a model, saving on material and print costs — both major sticking points in the technology’s adoption.

“You can imagine as you print a complex shape, you get a lot of interesting internal geometries that support the shape in the right places,” the company’s VP of Engineering Dave Veisz tells TechCrunch. “The net effect is that it’s going to reduce the amount of filament used and reduce the print time. So, you’re printing less to get your finished product.”

The time and cost savings varies, naturally, from project to project, owing much to different sizes and shapes of objects, but Veisz says the savings to both average out around 30 percent, effectively cutting the amount of material required to print an object by nearly one-third. Really geometrically complex objects, on the other hand, can have savings of upwards of 80 to 90 percent.

Mechanical Xylophoneneilmendoz 

This Instructable will actually show you how to make a mechanical glockenspiel as the keys are metal rather than wood (xylophone is a far better word though featuring very underused letter X). This instrument was a part of The Rock Band, composed of instruments that make music with rocks by throwing them through the air, slapping them and making them vibrate. The project was created at Autodesk's awesome Pier 9 digital fabrication workshop as part of their artist in residence program.
The rock parts of this instrument are the small pebbles that are launched at the keys. However, any small hard object would probably work. The aluminium keys were fabricated using a water jet cutter. If that tool is not available to you, then wooden keys could be used instead provided that the rest of the design is updated to accommodate their design. The xylophone will be controlled by MIDI so it is possible to control it to using most common music composition software, e.g. Logic, Cubase or Ableton.

The Easiest Arduino High Altitude Balloon Data Logger

Spaceshark 

High Altitude balloons are effective tools in conducting experiments and measuring data in the stratosphere. A successful launch can cost less than $200 and give insight and video of how our planet functions.

For hundreds of years, humans believed the Earth to be flat. High altitude weather balloons prove the Earth is in fact round. The idea of high altitude balloons or HABs is to mount a payload on a giant helium balloon. The balloons are then released, flying to heights of 100,000 feet. Once at these altitudes, the balloon pops and uses a parachute to float back to the ground often many miles from where it was first launched. HABs are great vehicles to get footage from the stratosphere, conduct science experiments, and collect data from high elevations.

3D Printer Buyers Guide

Alastair Jennings 

Frustrated with Fused Filament Fabrication? Read our 3D printing troubleshooting guide to the most common 3D printing problems and their solutions.

It’s amazing what your 3D printer can produce. But we’ve all had those infuriating moments when, despite everything, a seemingly simple model just refuses to print successfully.

You’ve checked the model, seen countless others make it without issue, but try as you might it just won’t print. What is it that keeps going wrong?

Here at ALL3DP, we’ve had our fair share of print failures. But the upside to those failures is that we’ve become finely tuned to recognizing and solving many common 3D printing problems.

Print, Assemble, Drive: The 3-D Printed Plastic Car
France Diep

In a convention center in Chicago, there's a living-room-sized 3-D printer that's just finished printing the parts for a driveable plastic car. The engineers working on the car -- including those involved in developing the plastic, the printer, and the car design -- are hoping to have something ready to drive off the premises by the end of the week.

The printer is the world's first large-scale 3-D printer that works with polymers, Oak Ridge National Laboratory engineer Lonnie Love told the Chicago Tribune. Oak Ridge worked with a company called Cincinnati Incorporated to develop the printer. "It builds some of the biggest parts in the world, faster than anything else," Love said.

Toyota’s Unveils New Maker Vehicle Concept — to Makers

Nathan Hurst

On Wednesday, Toyota unveiled a concept car not at an auto show, but to a panel of makers. It was a first of its kind and it was hosted by Make:, and with good reason — the car, called the U², was designed with makers in mind.

The makers, nearly a dozen, from bay-area institutions like the University of California and NASA, to startup founders and artists, crowded around the vehicle at San Francisco’s historic Palace of Fine Arts. Toyota was here, said the company’s American president, Kevin Hunter, to get feedback from makers, asking “How’d we do with this thing?”

Make Professional Quality Knives at Home

Zaphod Beetlebrox

Custom knifes are a staple of most professional cooks and chefs and can range in price from $200-$3000; however, you should be able to complete one knife for about $10 worth of steel and without power tools!

I wouldn't say that this is a very difficult project more that it requires a lot of patience and time, so get your audio books ready. Each knife requires about 20hr of work, there are ways to reduce this but it will require more money and probably more waiting.

Adolescente de 12 anos usa LEGO para criar impressora Braile

Um garoto de apenas 12 anos está mostrando ao mundo que não existe idade certa para serem iniciados os estudos sobre tecnologia. Shubham Banerjee vive em Santa Clara (nos Estados Unidos) e acabou de criar uma impressora Braile com peças de LEGO Mindstorms, sendo que ela possui funcionalidades completamente aplicáveis à realidade.

Shubham Banerjee gastou US$ 350, menos de 20% do que seria gasto por uma impressora comum, que gira em torno dos US$ 2 mil. Além das peças de LEGO Mindstorms, também há algumas outras adicionais, como é o caso do rolo de papel de calculadoras. Com os braços robóticos, a impressora é capaz de mover os módulos responsáveis pela perfuração do papel, podendo criar cartas completas em menos de 10 segundos.
