While the consumer sector struggles somewhat to sell the case for open source desktop 3D printers for everyday users, the adoption and exploration of open source printing platforms in science and research continues to ramp up and amaze. It is in the spirit of science to share your findings and your experimental frameworks, so this is no surprise.
Besides, who can pass up an article with a dropquote: “First time that robot-assisted evolution has been done in chemistry…”?
…The system is wonderfully simple. Using the RepRap 3D-printing platform a team of chemists at Glasgow University created a robot that can do incredibly precise experiments with no human input. The PlayStation camera then snaps pictures for further analysis.
“Right now, evolution only applies to complex cells with many terabytes of information but the open question is where did the information come from? We have shown that it is possible to evolve very simple chemistries with little information,” professor Lee Cronin from the department of chemistry at Glasgow University tells WIRED.co.uk.
Creating life from scratch is hard — and we know little about the origin of life before biology — but the use of simple robots is speeding up our understanding. The robot places four droplets of the same chemical composition into a Petri dish and uses the camera to see what happens. This process is repeated over and over again with randomly different compositions of droplets.
The droplets behave differently: some shake, some split up, some clump together and some wobble. Using a computer algorithm the robot selects the “fittest” molecules and carries these into the next experiment. The research is detailed in the journal Nature Communications.
“By hacking together this kit we have in effect built a highly sophisticated machine that can fully automate the life cycle of a chemical protocell model. We’ve then used the robot to explore lots of different types of ingredients to try and come up with interesting recipes that show ‘life-like’ behaviours,” Cronin says….
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! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. 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!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
