Collaborate Disseminate
Ordinarily, if you want to separate two objects that are glued together, harsh solvents or mechanical force are required – either one could damage the items. A new glue, however, releases its bond by simply turning to gas.Continue ReadingCategory: Mate… Continue reading Temporary glue releases bonded items by turning to gas
Hide glue has been around for thousands of years, and some of it is holding wood pieces three thousand years after application. It is made from animal protein, so vegetarians may want to stick to the petroleum-based adhesives. [Surjan Singh] wanted to see if its longevity made it a contender …read more

While we’ve certainly heard of epoxy resins that harden when exposed to light, usually all of the substance has to be exposed. A new additive causes resin to solidify when even only a bit of it gets lit up, however – plus it works underwater.Continue R… Continue reading Unique light-activated resin hardens even when underwater
Although so-called superglues can be quite useful, they’re typically made from harsh chemicals, plus it’s very difficult to “unstick” them once they’ve set. Now, however, scientists have created a plant-based superglue that can easily be removed when n… Continue reading Eco-friendly “releasable” superglue is made from plants
[CNCKitchen], like many others, is looking to make strong 3D prints. Using a high tech PLA bio copolyester compound, he printed a bunch of hooks in two different orientations. He used several different types of glue including epoxy and superglue. You can see the video of his results, below.

It takes a lot of energy to push a car-sized object a few hundred miles. Either a few gallons of gasoline or several thousand lithium batteries will get the job done. That’s certainly a lot of batteries, and a lot more potential to be unlocked for their use than hurling …read more

The promise of reusable sticky things, from Post-it Notes to Blu Tack, has never quite been fulfilled. They’re just never quite as sticky the second time around, or the third. But now, a team of engineers from University of Pennsylvania and L… Continue reading Snail slime inspires reversible, super-strong glue
Super glue, or cyanoacrylate as it is formally known, is one heck of a useful adhesive. Developed in the 20th century as a result of a program to create plastic gun sights, it is loved for its ability to bond all manner of materials quickly and effectively. Wood, metal, a …read more

The world of glues is wide and varied, and it pays to use the right glue for the job. When [Eric] needed to stick a wide and flat 3D printed mount onto the back of a PCB that had been weatherproofed with an uneven epoxy coating, he needed a gap-filling adhesive that would bond to both surfaces. It seemed like a job for the hot glue gun, but the surface was a bit larger than [Eric] was comfortable using with hot glue for. The larger the surface to be glued, the harder it is to do the whole thing before …read more

We’ve seen all sorts of 3D-printers on these pages before. From the small to the large, Cartesians and deltas, and printers that can squeeze out plastic, metal, and even concrete. But this appears to be the first time we’ve ever featured a paper-pulp extruding 3D-printer.
It’s fair to ask why the world would need such a thing, and its creator, [Beer Holthuis], has an obvious answer: the world has a lot of waste paper. Like 80 kg per person per year. Thankfully at least some of that is recycled, but that still leaves a lot of raw material that [Beer] …read more
