MIT researchers develop rapid 3D printing process with liquid metal

2024-01-30T12:40:00-05:00

News is circulating about a novel method for 3D printing liquid metals that was developed by researchers working at the Massachusetts Institute of Technology (MIT) Self-Assembly Lab.

The invention can print furniture-sized components using molten aluminum and a ceramic nozzle graphite printer. They say their discovery works without re-melting the recycled materials, as is the case with many current technologies. It resembles a small furnace into which book-sized blocks of the material are fed. The technique, called liquid metal printing (LMP), creates material that is durable enough to withstand CNC milling and other steps in the post-design delivery process.

The hope now is to refine the technique to allow for more consistent and higher-resolution prints. Such rapid and deployable solutions could become an attractive choice for architectural designers looking to scale up development and building projects in the future.

Aleatory Architectures: the bright future of self-assembling granular materials

2015-11-10T20:30:00-05:00

But some designers are toying with another idea—that there’s a different way to build that exploits randomness rather than avoids it. This kind of building will rely on new kinds of granular materials that when tipped into place, bind together in ways that provide structural stability. [...] Sean Keller at the Illinois Institute of Technology in Chicago and Heinrich Jaeger at the University of Chicago explain how this kind of “aleatory architecture” is finally becoming possible.

That will have a profound effect on the process of design. “As a result, preplanning is freed from considering the local structural detail,” say Keller and Jaeger. “Instead, the main task now becomes generating the proper particle shapes as well as the overall boundary and processing conditions to guarantee that the desired target structure will be mechanically stable when realized.”

NASA looks to robots and 3D printers for huge, self-constructing, orbiting structures

2013-09-04T18:09:00-04:00

Instead of specially engineering spacecraft components to fit into a rocket, NASA could densely pack materials like fiber and polymer into existing spacecraft and create the components while orbiting the planet. This cuts down on cost and opens up the possibility for larger spacecraft.

The Self-Assembly Line

2012-03-12T14:24:00-04:00

The Self-Assembly Line is a large-scale version of a self-assembly virus capsid, demonstrated as an interactive and performative structure. A discrete set of modules are activated by stochastic rotation from a larger container/structure that forces the interaction between units. By changing the external conditions, the geometry of the unit, the attraction of the units and the number of units supplied, the desired global configuration can be programmed.

Skylar Tibbits and Arthur Olson, have presented a large-scale installation, The Self-Assembly Line, at the 2012 TED Conference in Long Beach, CA. The Self-Assembly Line is a large-scale version of a self-assembly virus module, demonstrated as an interactive and performative structure. A discrete set of modules are activated by stochastic rotation from a larger container/structure that forces the interaction between units. The unit geometry and attraction mechanisms (magnetics) ensure the units will come into contact with one another and auto-align into locally-correct configurations. Overtime as more units come into contact, break away, and reconnect, larger, furniture scale elements, emerge. Given different sets of unit geometries and attraction polarities various structures could be achieved. By changing the external conditions, the geometry of the unit, the attraction of the units and the number of units supplied, the desired global configuration can be programmed.
