ReactionWare 3D Printed Medicine

August 5, 2012 by Richard Steele 33 Comments

The University of Glasgow has released a Chemistry research paper covering the applicational process of printing pharmaceutical compounds.

Yes thats correct actually printing medication. Using various feedstock of chemicals they see a future where manufacturing your medication from home will be possible. Using standard 3D printing technology it is possible to assemble pre-filled “vessels” in such a way that the required chemical reactions take place to produce the required medication. This will be like having a minature medication manufacturing facility in your home. The possible implications of this could be far reaching.

There would need to be a locked down software etc or certain chemcials restrictions to prevent the misuse of this technology. Prof [Lee Cronin], who came up with the paper’s principal has called this process “reactionware”

Professor [Cronin] found, using this fabrication process, that even the most complicated of vessels could be built relatively quickly in just a few hours.

Printing Organs With A 3D Printer

July 2, 2012 by Brian Benchoff 24 Comments

[Jordan Miller], [Christopher Chen], and a whole bunch of other researchers at the department of bioengineering at U Penn have figured out a way to print 3D tissues using a 3D printer. In this case, a RepRap modified to print sugar.

Traditional means of constructing living 3D tissues face a problem – in a living body, there’s a whole bunch of vasculature sending Oxygen and nutrients to the interior cells. In vitro, these nutrients can’t get to the cells in the core of a mass of tissue. [Jordan], [Chris], et al. solved this problem by printing a three-dimensional sugar lattice. After encasing this lattice in a gel embedded with living cells, the sugar can be dissolved and the nutrients pumped through the now hollow capillaries in the gel.

If you have access to Nature, the full text article is available here. There’s also a great video showing off this technique after the break.

Don’t Bring Your 3d Printer To MakerFaire

June 25, 2012 by Caleb Kraft 48 Comments

This could easily be called “the year of the 3d printer”. They are in the news, in every hackerspace, and at every event. This last one is the one I’m going to focus on here. All the coverage we’ve seen as well as our personal experience shows that MakerFaires are filled with 3d printers. At MakerFaire K. C., there were so many that I lost count. I didn’t even bother taking pictures or stopping to look after a while. Many were makerbots, though a few repraps were present too.

If you want to be noticed at MakerFaire, DON’T BRING A 3D PRINTER AS YOUR SOLE DISPLAY.

InMoov: A 3d Printed Animatronic Hand You Can Download

June 9, 2012 by Caleb Kraft 20 Comments

[Hairygael] has been hard at work designing and building this robot structure that can be completely 3d printed. He’s admittedly not a big electronics person, so most of his focus has been on the design and construction of the bot frame. So far, he as a fully 3d printable (and available for download) hand that you can see in action after the break. Once printed, you’ll have to drill it for your own servos and add your own control system.

You can see the action is quite nice and sturdy in the video. [Hairygael] laments his lack of electronics knowledge when you see him hit roadblocks like multiple finger control. But, just as he points out in the video, we’re positive that some of you who are more familiar with that end of things will undoubtedly make this work well.

3d Printing, The New Frontier Of Piracy?

May 31, 2012 by Caleb Kraft 89 Comments

We’ve all heard the countless arguments about piracy in digital media. However, it appears that 3d printing or other rapid prototyping systems are bringing legal issues to a more physical world. The story goes like this: [Thomas] bought a 3d printer. He’s a big fan of warhammer figurines. He spends tons of time creating some custom warhammer figures, and uploads them to thingaverse. Games Workshop, the owners of Warhammer, unleashed the lawyers and had the items removed.

There are so many angles to this story, the mind boggles. If I were an artist, and someone else was uploading copies of my work, essentially stopping my revenue, it would suck. Then again, if I were lucky enough to have a fanatical fan base that spread the love for my product with excitement and zeal, I might want to encourage them. Neither of those thoughts however, cover the legal issue at the base here. We don’t have an answer for you. Sorry. You’ll probably be seeing this issue pop up more and more often in the future.

We encourage you to make our logo. Though we haven’t bothered to ask our lawyers.

3d Printing Ice Sculptures

May 30, 2012 by Caleb Kraft 18 Comments

[Jared Kotoff] asked an interesting question on Facebook. He asked if we had ever seen 3d printing in ice before. Though we couldn’t find anything in our archives, he managed to find a project that makes 3d printed ice sculptures. To do this, they actually print two materials inside a chamber that is -8 degrees Fahrenheit. The first material is Shortening Methyl Esther (SME) that is used as a scaffold or mold. The second material is just water, but the tip is heated to 68 degrees to keep it from freezing in the nozzle. They do two passes of water for every layer of SME, and scan with a laser and perform corrections after every five layers.

Once the print is completed, the sculpture has to be scraped clean of SME and then soaked in kerosine to remove the last of it. There are several pictures at the linked article, but sadly no video.

3d Printing A Mini Lathe

May 21, 2012 by Caleb Kraft 21 Comments

While browsing on one of our regularly visited sites, RobotsDreams, we found this interesting little video. Here, [Sublime] is showing off his 3d printed mini lathe. In the video he mentions that all the files are available for download so you could make one for yourself, but there were unfortunately no links. A quick bit of googling and we found some more information. We found the project on Thiniverse, though reading through the comments it seems that [Sublime] no longer uses Thingiverse. You can now find the files on his GitHub account to make your own.

The design seems very solid and looks like it could handle some basic jobs. As [Sublime] points out in the video below, you already know what parts are going to wear out fast and can simply print a few extras to have on hand. While that may seem somewhat wasteful, he also points out that he’s using PLA which is compostable and much easier to recycle.
