3DPrintedFishTags

The latest fish tag design is streamlined and looks different from earlier tag designs.
CSIRO scientists are using 3D printing to build a new generation of hi-tech fish tags made of titanium. The aim is to use the tags to track big fish such as marlin, tuna, swordfish, trevally and sharks for longer periods.

CSIRO is printing the tags at its 3D printing facility, Lab 22, in Melbourne. The tags are printed overnight and then shipped to Tasmania where marine scientists are trialing them.

Tags are made of titanium for several reasons: the metal is strong, resists the salty corrosiveness of the marine environment, and is biocompatible (non-toxic to living tissues).

One of the advantages of 3D printing is that it enables rapid manufacture of multiple design variations which can then be tested simultaneously. "Using our Arcam 3D printing machine, we've been able to re-design and make a series of modified tags within a week," says John Barnes, who leads CSIRO's research in titanium technologies.

"When our marine science colleagues asked us to help build a better fish tag, we were able to send them new prototypes before their next trip to sea," he adds.

CSIRO's 3D printing facility prints metal items layer by layer out of fused metal powder. Had the scientists been using conventional tags which are machined out of metal blocks, it would have taken a couple of months to design, manufacture and receive the new designs for testing.

"Our early trials showed that the textured surface worked well in improving retention of the tag, but we need to fine-tune the design of the tag tip to make sure that it pierces the fish skin as easily as possible," says John.

"The fast turnaround speeds up the design process – it's very easy to incorporate amendments to designs. 3D printing enables very fast testing of new product designs, which why it's so attractive to manufacturers wanting to trial new products."

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don't forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you've made a cool project that combines 3D printing and electronics, be sure to let us know, and we'll feature it here!

srf08 making audible "chrimp" while ranging

Hi,

I am using an ultrasonic rangefinder srf08 with an arduino and almost everything is working well. Signal is stable and accurate. But for my suprise every time the sensor emitts the 40khz ping it also has an audible, much lower frequecy sound to it....

DLD Conference: “The 3D printing and manufacturing revolution” #3dthursday

Posted: 14 Feb 2013 01:00 AM PST

Check out this video of a 3D printing industry panel at DLD13 that includes Eric de Bruijn, co-founder of Ultimaker, Peter Weijmarshausen, CEO of Shapeways, Indo Ederer, CEO of Voxeljet, and Pablos Holman, "an advisor to MakerBot," to get a sense of a range of the approaches to 3D printing right now:

Spit out of the open mouth of the Makerbot, a complete bracelet lands on the floor. It doesn't lie there for long until it is collected by one of the audience. Three-dimensional printing is ready to conquer the masses. Toys? Cars? Even food? It's all imaginable.

"My six-year-old daughter prints out her own shoes," stated Pablos Holman of Intellectual Ventures Lab, where he is part of a wide variety of futuristic invention projects. "I'm sure in no time we'll be printing out smoothies, strawberries and other foods." Most beautiful to him is that we can all realize our own projects with those machines, from jewelry to robot parts.

"We've heard about parts of micro satellites that have been printed and sent to outer space," said Peter Weijmarshausen, CEO of Shapeways. His company makes it possible to create one single product for the same price as thousands of them. Any material or product is possible as the technology is evolving fast. For now, Shapeways allows users to choose from 25 different materials, including metals, ceramics and glass, in order to give shape to an individual's product vision.

In the industrial sector where Ingo Ederer works as CEO of Voxeljet, 3D printing cannot be missed anymore. More money is involved here, and bigger printers.

You will know when 3D printing has reached mainstream, Weijmarshausen argued: "when it's not about the technology anymore but when we just like what it provides!" The most alluring characteristic, he said, is that it's environmentally friendly as there is no shipping involved.

I'd like to see children getting taught in school how the technology works, added Erik de Bruijn, Co-Founder and Designer at Ultimaker. In his view, 3D printing will enter the masses within the next five years. He was also the one standing for many hours in the hallways of DLD and enthusiastically explaining anyone interested of what this great new thing is all about, how "it improves people's lives."

Shapeways’ 3-D Printing Factory Tour Reveals the Handmade Future #3dthursday

ShapewaysTour

From WIRED Design:

The first thing you notice when you visit the Shapeways Factory of the Future in Long Island City is the dust. It's the white nylon material that is used in laser sintering. It gets everywhere.

The second thing is the sheer number of people involved. When we talk about 3-D printing, we emphasize its seamlessness and ease of use. "Your ideas made real with Shapeways 3-D printing," says Shapeways' front page. It's easy to overlook the number of steps between sending in a CAD file and getting the result delivered to your home. All of those steps involve a human.

We'd like to show you how Shapeways makes ideas real.
