Matthew Davis’ Arcus is a 3D-printable rubber band gatling gun. Its unorthodox appearance is more than just for show. Unlike most rubber band guns, the Arcus uses the energy from the rubber bands being shot out to rotate the barrels and continue the barrage. Grab the 3D models and directions on Instructables.
Nexi Tech shows us how to make some truly unique speakers using value-priced parts. The electronics are set into organic looking enclosures designed by Ondra Chotovinsky. The 3D printer he used is the $500 Creality3D CR 10S, which makes great big prints cheap.
Because of their relatively slow speed, time-lapse videos are the best way to showcase 3D printer builds. Make Anything shows off a neat technique that perfectly synchronizes each layer printed with a still camera’s shutter, resulting in a really slick and smooth visual effect.
LEGO fan Matt Denton managed to 3D print another jumbo-sized version of a classic LEGO Technic kit – their 1979 bulldozer model. Just like the original, this supersized version was assembled from nearly 400 parts. Unlike the original, this one took 600 hours to print.
Maker Ivan Miranda shows off one of the cooler 3D printed objects we’ve seen – an oversize replica of one of those rotating rubber stamps, made possible thanks to pliable, rubberlike Fiberflex 40D filament. He neglected to mirror the letters, but it’s still a nifty build.
LEGO makes regular size bricks, and larger Duplo bricks for little kids. But the bricks in Matt Denton’s awesome build are way bigger. He used a Lulzbot 3D printer to render all 98 pieces from a classic LEGO Technic go-kart kit, resulting in a 5x larger version of the original.
While 3D printers typically use filaments made purely from plastic, Make Anything shows off how a special composite filament called Timberfill can be used to create sandable, stainable wooden objects, like the cool acorn-shaped storage containers shown in the video.
We’ve all seen laser beams which project images using a persistence of vision effect. While the professional gear does it with moving mirrors, Yertle Vert shows off a neat build using 3D-printed cams and a laser pointer to achieve a similar effect. Instructions on Thingiverse.
Designer Paul Braddock of the Mold3D Channel demonstrates how to use objects made with a 3D printer to create silicone molds for casting items from a mix of metal powder and resin, giving them a sturdy and substantial part with a weathered metallic look with actual rust.
Eric Harrell used his 3D printer to render an accurate, fully-functional scale model of the LS3 V8 engine from a Chevrolet Camaro. It took him over 200 hours to print the finished model. If you’ve got the time, the printer, and the filament, grab the plans from Thingiverse.
High tech design studio Nervous System has outdone themselves, with the creation of truly stunning neckties which double as wearable works of art. The interlocking pieces are printed from nylon, and are hinged to move fluidly. Each is printed to order, so be patient.
