Here is a cool project on Kickstarter:

http://www.kickstarter.com/projects/920064946/oscilloscope-watch

it is an oscilloscope watch! Now, how cool is that! Oscilloscope you wear on your wrist!




The enclosure is 3d printed, you can see an Afinia in background of the video. Gabriel (the creator) planes to have plastic case similar to modern watchers, but I like this rough 3d printed style. It is more geek kind of cool.

From the 3Dsimo project Indiegogo page:

3Dsimo as a first on the world provides to user the possibility to choose print options on a digital display. The adjustability of temperature and speed of materials throughput now offer amazing opportunities for your creativity. We can handle various materials as ABS, PLA, PVA (water-soluble material), nylon at different temperatures in order to achieve fast filling or even print in the air.

Other options include backlight, turn on preheating or memory for storing settings. These parameters are used to determine the appropriate method of drawing.
Do not be limited by the choice of materials, for example choose between golden, silver, wooden or flexible PLA. Over time, new materials will be increasing due to the growing trend of 3D printing. Our 3Dsimo is fully prepared for this due to configurability of all parameters and thermal feedback for determining the exact temperature.

How it works?

3Dsimo is so simple to use as a pencil. Everyone who have ever draw with pencil will not have a problem to use 3Dsimo. After plugging it in you set the desired speed and temperature according to the material (these data will be appended together with 3Dsimo and new materials will be updated). 3Dsimo is based on the principle of FDM technology thus extruding plastic material through the hot end. If you want to print into the air or create infill of any object you can do it easily and quickly. There is no problem just make your choice. After a while of use you will find that with 3Dsimo you can create fantastic objects.

3Dsimo has many utilization:
Repairing of plastic devices
Bonding and assembling models of 3D printers
Repair abortive print (due to repair you don’t need to enter new several hours lasting print)
Creating jewelry
To implement your ideas
Simply for the joy of modeling

From Fundable campaign:

Built upon the philosophy of freedom, Aleph Objects, Inc. is transforming the 3D printer industry. Based in Loveland, Colorado, we founded the LulzBot brand on a dedication to the free and open exchange of information and innovation, and in doing so, have made a name for ourselves in the growing maker community. In fact, LulzBot 3D printers are the only 3D printers to carry the Free Software Foundation's Respects Your Freedom certification. Our TAZ printer is our fifth generation printer and is representative of the best and brightest ideas sourced from a global community of passionate innovators.
Why TAZ 2 is the Best Desktop 3D Printer for You:

• TAZ offers the largest build area of any assembled desktop 3D printer. Print your large part in one complete piece or multitask by printing many smaller prints simultaneously.
• New to TAZ 2 — print without being attached to a computer. TAZ 2 comes with a LCD display with a SD card reader for untethered printing. 
• You have the flexibility to use the optimal material for your project by choosing from the broadest selection of printing material.
• Minimize your ongoing printing cost with free software upgrades, free upgraded designs and the ability to do self repair.
• Create detailed, higher quality prints with 75 micron print resolution.
• Finish your prints faster and more reliably with excellent hot-end control and 200mm/s print speed.

By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
In a recent experiment they demonstrated that a community of Staphylococcus aureus, which can cause some skin infections, became more resistant to antibiotics when it was contained within a larger community of Pseudomonas aeruginosa, a bacteria involved in various diseases, including cystic fibrosis.
The work was published this week in the Proceedings of the National Academy of Sciences.
The researchers use a novel 3-D printing technology to build homes for bacteria at a microscopic level. Their method uses a laser to construct protein "cages" around bacteria in gelatin. The resulting structures can be of almost any shape or size, and can be moved around in relationship to other structures containing bacterial microcommunities.
The method should enable an entirely new class of experiments that better approximate the conditions that bacteria encounter in actual biological environments, such as those in the human body.

Desktop spin casting machine would enable you to make series of objects with rapid molding process. This could develop into very interesting sector of machines and products.

Co-Founder of TeMAAK and Inventor of the RotoMAAK, Mark VanDiepenbos presents the RotoMAAK desktop rotational molding machine and demonstrates its use.
The RotoMAAK evenly distributes 2 part epoxies, as well as other rotational mold materials, to make parts out of 3d printed molds, silicon molds, or other types of molds in as little as 5 to 10 minutes. More details and specs coming soon, including the date for the Kickstarter campaign. Sign up on their website www.rotomaak.com to receive email notifications about its development and Kickstarter Launch.
Mark VanDiepenbos is a part of Makerspace Goshen, the same group that John Oly and Steve Wygant of www.seemecnc.com (Rostock Max and Orion 3D printers) are a part of.

If you are not sure what spin casting is (like I was) here is wikipedia page on it: http://en.wikipedia.org/wiki/Spin_casting

Here is a link to another DIY spin casting centrifuge that illustrates the process:

There are many 3d printing projects in the field of archery. This 3d printed arrow fletcher has very organic and futuristic design.


























From project page:

Where is the future of 3D printed product design headed and why? Niche and pricy markets like arrow fletchers may see the soonest market disruption. A good arrow fletcher holds feathers accurately and securely in place while glue dries. This fletcher was printed and delivered at the market price of current ones.
