An Elegoo Mars DLP resin 3D printer, straight to my doorstep for a few hundred bucks. What a time to be alive. Resin-based 3D printers using stereolithography (SLA) and especially digital light processing (DLP) are getting more common and much more affordable. Prosumer-level options like Formlabs and the Prusa SL1 exist, but more economical printers […]
3D printing is a great way to create complex geometric forms. However, it can be very slow, and parts may lack strength compared to other alternatives. There are other ways to take advantage of this technology however, as shown in the build of this tidy voronoi lamp. The lamp is so-called for its voronoi-patterned base, […]
Thermal inserts are a big thing when it comes to engineering with plastic. They make it easy to use threaded fasteners with plastic parts, and they work great with 3D printing too. There’s a bit of a knack to installing them without damaging your workpiece, however, and [John Culbertson] wanted to make using them as […]
It’s interesting to peek into other scenes and niches and see how they intersect with things that one may find commonplace, like 3D printing. In this case, [NewToOldGuns] wrote a guest blog post for PyramydAir (a retailer, so be prepared for a lot of product links) about how 3D printing has completely transformed the experience […]
Many of us are happy to spend hours cooking up a solution that saves us seconds, if success means never having to do a hated task again. [frankensteinhadason] molds enough silicone parts that he grew tired of all the manual labor involved, so he built a silicone injector to do it for him. Now, all […]
A single board computer on a desk is fine for quick demos but for taking it into the wild (or even the rest of the house) you’re going to want a little more safety from debris, ESD, and drops. As SBCs get more useful this becomes an increasingly relevant problem to solve, plus a slick […]
If you’re like the average clock user, you’ve probably gotten annoyed at reading analog clocks before. Typically, the solution is just to use a digital timepiece, but [sjm4306] has opted to make a small word clock that you can carry with you wherever you go to remind you of the time in the English language. […]
It’s a perennial of breathless British tabloid scare reporting that 3D printers will unleash a tide of weapons upon the streets. But perhaps it might actually be time for Brits lock up their children, because London’s Metropolitan Police have announced their first prosecution for 3D printing a handgun. The gun pictured appears to be a […]
An Israeli start-up company, Redefine Meat recently raisedabout $6 million to perfect and commercialize its technology to 3D print meat alternatives, sometimes called alt-meat. The company claims that producing animal protein for consumption is unsustainable but that their product reduces environmental impact by 95% and has other benefits such as containing no cholesterol and a […]
The ballistics of humble potato is a time-honoured research topic for everyone who likes things that go bang. The focus of such work is usually on the launcher itself, with the projectiles being little more than an afterthought. [drenehtsral] decided that the wares of the local organic ammunition supplier were not good enough for him […]
