OpenStructures is a Modular Building System for the RepRap Age

Modular construction toys like LEGO and Meccano are great for prototyping, but they aren’t so great for large builds. OpenStructures promises to be a modular building system for projects large …read more Continue reading OpenStructures is a Modular Building System for the RepRap Age

Phase Change Materials for Flexible and Strong Robots

Top left of image shows a picture of a purplish-grey sea cucumber. Above the cucumber is the word "bio-inspiration." Arrows come from the cucumber to anthropomorphized cartoons of it saying "rigid" at the top with a cartoon sea cucumber standing straight up with spikes and the arrow captioned "soft" pointing down showing a crawling sea cucumber that looks more like a slug. To the right of the cucumber images is a set of three images stacked top to bottom. The top image is of a silver sphere with a zoomed-in atomic diagram with aligned magnetic poles next to it saying "solid state." The middle image shows arrows going up and down next to a snowflake and an artistic rendering of magnetic fields labeled "transition." The bottom image of this section shows a reddish sphere next to a zoomed-in atomic diagram where the magnetic poles are not aligned labeled "liquid state."

Shape shifters have long been the stuff of speculative fiction, but researchers in China have developed a magnetoactive phase transitional matter (MPTM) that makes Odo slipping through an air vent …read more Continue reading Phase Change Materials for Flexible and Strong Robots

5-Axis Printer Wants to Design Itself

The underside of the rotational base of the Gen5X 3D printer. A belt connects a pulley on the bottom of the stage to a stepper motor on the right side. The carriage for the stage looks organic in nature and is printed in bright orange PLA. The stage can rotate within the carriage which is mounted on two stainless steel rods connected to teal mounting points on either side of the printer (ends of the X-axis).

RepRap 3D printers were designed with the ultimate goal of self-replicating machines. The generatively-designed Gen5X printer by [Ric Real] brings the design step of that process closer to reality. While …read more Continue reading 5-Axis Printer Wants to Design Itself
