's Jonathan Bachrach and Saul Griffith, former BB guestblogger and MacArthur "Genius" received a DARPA grant to develop algorithms that convert 3D objects into 2D pattern pieces. Those pieces can then be fabricated out of myriad materials and fastened together to make the 3D object. While DARPA is a defense department outfit, Saul and Jonathan were encouraged to find other non-defense uses for their futuristic design/manufacturing tech. Of course, they had lots of fun doing just that. Last year, Saul showed me some ingenious snap-together kids toys they had prototyped. And now, they've teamed up with Betabrand to apply their algorithm to clothing, such as this new "DARPA Hoodie." From an interview with Bachrach:
My end-to-end software tool chain takes 3D surface files and produces 2D vector files with nested flat parts with all the necessary part numbers, bend lines, angles and joinery ready to cut and easy to assemble.
The bend and joinery mechanisms are completely customizable for the particular material type and desired look such as pop rivets, welded seams, and press fit.
The tool creates the opportunity for greatly lowering the time of manufacturing and for creating a unique algorithmic design quality.
The 2D panels are created based on a customizable goodness measure that first ensures that panels are flattenable with low distortion and from there guides the formation of panels towards a user’s desired shape, for example, equal sized, fewest number, etc.
We have previously applied this algorithm towards making a better t-shirt and more recently have been working with Betabrand on making a hoodie.
For clothing, the automatic panelizer opens up the possibility for custom clothing and better fits for stiffer materials.
The hoody was created algorithmically from a 3D triangular mesh for an average six foot male, downsampled to 100 triangles, deconstructed into 12 panels of high grade nylon, and finally sewn together with externally visible red thread.
A group of tech firms will meet today to plan the filing of an amicus brief in support of lawsuit to challenge U.S. President Donald Trump’s “Muslim Ban.” Trump’s order was issued on Friday, and restricts immigration from seven Muslim-majority countries in which Trump has no business interests. Adjacent Muslim-majority nations in which Trump does […]
The World Economic Forum asked “leaders from business, government, academia and nongovernmental and international organizations” to take a survey on the potential risks and benefits of different emerging technologies. They seemed to think the space technologies will have little benefit and pose little risk. Energy capture, storage, and transmission has the great promise and little […]
The graphene temporary tattoo seen here is the thinnest epidermal electronic device ever and according to the University of Texas at Austin researchers who developed it, the device can take some medical measurements as accurately as bulky wearable sensors like EKG monitors. From IEEE Spectrum: Graphene’s conformity to the skin might be what enables the […]
Making people aware of goods and services in the digital age requires an array of new strategies from social media and email to number-crunching tools like Google Analytics. To get a handle on the techniques used to capture attention and convert traffic into dollars in a crowded online environment, the Full-Stack Marketer Bundle offers 22 hours of training to get […]

Python is immensely popular in the data science world for the same reason it is in most other areas of computing—it has highly readable syntax and is suitable for anything from short scripts to massive web services. One of its most exciting, newest applications, however, is in machine learning. You can dive into this booming […]
