Yep, it???s a QR code stencil generator! We present QR_STENCILER, a free, fully-automated utility which converts QR codes into vector-based stencil patterns suitable for laser-cutting. Additionally, we present QR_HOBO_CODES, a series of one hundred QR stencil designs which, covertly marked in urban spaces, may be used to warn people about danger or clue them into good situations. The QR_STENCILER and the QR_HOBO_CODES join the Adjustable Pie Chart Stencil in our suite of homebrew ???infoviz graffiti??? tools for locative and situated information display.

Exporting STL files from SketchUp gets easier

Exporting STL files from SketchUp gets easier

A small modification to export STL files more easily.

Thingiverse user Brett Beauregard has tweaked a SketchUp plugin by Nathan Bromham and Konrad Shroeder to speed up his own work. Their plugin exports files from the free version of SketchUp to STL or DXF (an extremely useful addition). Brett always exports his STL files with the same settings, so he altered the code of the plugin to allow the setting to be hard-set into the program.

It???s a small change, but if you???re exporting dozens of STL files, it would save a lot of aggravation. This is one of the wonderful things about working with open-source software; you can just crack open the code and change things if something bothers you.

Deliciously tasty 3D printing???

University of Exeter develops first 3D chocolate printer!

3D Chocolate printer

Researchers at the University of Exeter in the UK must all have a sweet tooth as they???ve developed a working prototype 3D food printer. Instead of polymer, metal or ceramics this printer uses chocolate as an ink. Yum! Video after the jump???

The research led by Dr. Liang Hao was conducted as part of the Research Councils UK (RCUK) Digital Economy Programme by the University of Exeter in collaboration with the Brunel University and software developer Delcam to look into practical applications of novel design & technologies.

Already interest has been expressed to further develop and commercialise this technology. Clearly, chocolate as a printable material is just the beginning, its conceivable that multiple ingredients or food colour additives could be printed by one machine. Ingredients could be cooked or processed as part of the printing too ??? allowing Gordon Ramsey-esque chefs to focus more time on yelling and swearing.

Most of all I???m impressed the researchers are looking at the larger picture of what chocolate means to consumers ??? the idea that chocolate is a shared cultural activity. As such they have plans for an online shared community of 3D models. Sounds like a foodie???s version of Thingiverse to me! I think the way we design, select and buy chocolate gifts is about to take a jump into the digital age???

Staining wood sheet materials ??? 7 different woods, 6 different stains

Staining wood sheet materials ??? 7 different woods, 6 different stains

Josh Reuss makes 42 wood stain samples

Ponoko???s own Josh Reuss is always putting up nifty experiments, tips & tricks in the Ponoko forum.

Earlier this year, Josh decided to try out a variety of stains on some scrap pieces of wood material. (These are all wood materials for laser cutting with your Personal Factory btw.)

He reported on his staining experiments, detailing the best methods for applying and which stains looked best on which materials. Check it out, and if you???ve done any staining or painting yourself, feel free to add your results and what you???ve learned to the forums.

Links to each material and stain used are after the jump.

The materials:
??? Bamboo (blonde)
??? Bamboo (amber)
??? Bamboo (amber 3ply)
??? Walnut (veneer mdf)
??? White Oak (veneer mdf)
??? EuroMaple
??? MDF

The stains:
??? Behlen Solar-Lux Stain (Jet Black)
??? Butch Block Conditioner
??? Teak Oil Finish
??? Danish Oil (dark walnut)
??? Danish Oil (natural)
??? Minwax Ebony
