Living in the future is pretty great. And Nokia thinks so too. The first cellphone company to embrace the at home 3D printing community, Nokia will release a “3DK” toolkit with all the info needed to make your own case for their Lumia 820 smartphones. Yet another reason to stroll over to the AOC and rock those 3D printers! Read more about it at Gigaom.com and on Nokia’s blog.

It is what it says it is, and it does a pretty good job. Make a protest poster you can be proud of! Make some t shirts for your band that look like you know someone who knows how to draw! The Online Stencil Generator can make a working stencil out of any image in your database or on the web. The program also gives you a little freedom to edit, with 17 different versions of the image in stencil form, from mostly white to mostly black, and the ability to make a stencil out of either the positive or the negative of the image. Unfortunately the Stencil Generator generates jpegs, not vector art. But you’re two steps away from having a file ready for cutting on the laser cutter or our vinyl cutter!
If it’s your dream to work with the kinds of rapid prototyping, laser cutting, and other 3D technology that we write about on this blog, now’s your chance.
The AOC is hiring a new Advanced Output Center Manager. Details can be found here.

One thing that many people have not tried to laser engrave here is food items. In the past I had experimented with engraving into an apple and the results worked pretty well. Here is another example we’ve come across by somebody else where they engraved into a banana. The result is a banana with a custom pattern that is still very much edible.
This is a pretty impressive if yet crude hack. The inkjet printer prints into the powder and the combination of the ink and powder will create a solid. The solid is built up layer by layer by removing one sheet at a time and printing the next layer. It appears to be a very tedious method but it works. This is also how Z-Corp 3d printers work, however their method is a lot less tedious. The Z-Corp printers have a built in tray and as the print cartridge places ink into the powder, the tray automatically lowers and repeats until the part is complete.
Join Chris Reilly and Taylor Hokanson for a demo and short lecture on the DIYLILCNC project at Dorkbot Chicago. We’ll be covering the history and evolution of the DIYLILCNC project, some general background of CNC technology, some of the shortcomings of the present state of CNC and how those are addressed by open-source hardware projects like the DIYLILCNC. We’ll also go over the specs of the DIYLILCNC, giving details about how it is built and its functions.

Dorkbot: People doing strange things with electricity. The main goals of Dorkbot are: to create an informal, friendly environment in which people can talk about the work they’re doing and to foster discussion about that work; to help bring together people from different backgrounds who are interested in similar things; to give us all an opportunity to see the strange things our neighbors are doing with electricity. Dorkbot isn’t really a forum for formal artist talks or lectures, but rather a chance for diverse people to have friendly conversations about interesting ideas.
The Mcor Matrix is a desktop 3D printer that uses standard letter-size office paper to print 3D objects from digital CAD files. The Matrix uses a technique called laminated object modeling, reproducing 3D objects by layering thin sheet material, similar to a topographical map. A file sent to the printer is divided up into horizontal cr0ss-sections; a blade or other cutting device (many other LOM printers use lasers) cuts each profile into a sheet of material, which is then laid down on a work bed. Subsequent layers are glued to previous sheets, eventually forming the whole model. Waste paper is left in place, acting as a support material for undercuts in the object. After printing, waste paper is removed (presumably by hand) for recycling. The print resolution is about 0.003″ using standard 20lb. bond paper; thicker paper can be used for a coarser resolution (0.007″) and increased printing speed. Wired has a great pdf outlining the Matrix’s printing process.
The Matrix retails for about $30,000, comparable to many other 3D printers. Where it shines in terms of cost is it’s material; paper, of course, is relatively cheap, especially in comparison to other plastic or resin-based materials used in other printers. You can even use printed-on photocopy paper. Other consumables are a PVA-based adhesive used to glue the layers together; currently Mcor has no specific pricing information available for the adhesive, but generally PVA-based glues are cheap on the order of Elmer’s glue or wood glue. Replaceable tungsten-carbide blades are used to cut profiles out of each layer; currently Mcor has no specific pricing information available for the blades.
Paper as a prototyping material has the advantage of being highly recyclable/reusable, giving the Matrix a leg up on 3D print users who make sustainability a priority. Parts durability is obviously fairly low, making the Matrix more suited to visualizing 3D designs as opposed to making more durable/usable parts. I haven’t handled an Matrix print personally, but my guess is the durability would be a bit more than that of a Zcorp print.
Just wanted to do a quick post to show off the latest from Claudia Hart. She often uses the Rapid Prototyper to print out manipulated 3d figures. The latest model to be printed is a woman laying across the back of a bear.
Erich Ginder’s new “Materialized” vase is the first in a series of objects created by scanning and decimating heavily adorned forms with high resolution laser scanners, resulting in jewel like abstractions free of the designer’s hand.
Myungah Hyon’s bookmaking class has some awesome examples of laser cutting from last semester. These students used various methods of laser cutting to create interesting books and other objects.
SangHee Jun used the laser cutter to cut sheets of matboard and overlaid them in a book format to create this amazing looking forest book.
EunSon Kim uses the laser cutter to etch various designs into acrylic.
Ayla Kindle used the laser cutter to create this really nice looking layered design that is inset in the middle of a book.
Sangeetha Ravichandran used the laser cutter to etch into wood blocks.
This laser etched and cut piece of masonite by Georgiana Rhua has a little backpack that holds a passport.
Christine Waller uses the laser cutter to etch images into acrylic. These remind me of cyanotype photographs when placed on the light blue paper.
This design by Xin Yao reminds me of topographical maps.
