Matt Denton of Mantis Hacks has been working on a LEGO-inspired go-kart made with larger than life 3D-printed plastic bricks. After countless hours on the project, he’s ready to take his creation for a test drive. You can check out the full series of build videos here.
THE BEST 3d Printed
Using a high-tech 3D printer that can print up to 8 different materials with a single nozzle, engineers from Wyss Institute and Harvard SEAS are showing how they can create tiny soft robots which use a mix of hard and flexible substances. By introducing a vacuum into its chambers, it’s able to walk without motors.
Engineer James Bruton is always building amazing things in his workshop. He recently got his hands on a LiDAR scanner unit which can enable 3D computer vision and capture navigational data. He used the device to guide a robot that looks for movement all around it, then turns to fire at what it detected. Demo starts at 17:54.
UK shop ReadyPlayerTwo creates neat 3-dimensional logo signs inspired by classic video game and computer systems. Each one is 3D printed from PLA plastic to accurately replicate the original color scheme, and has neodymium magnets securely mounted inside. They also make personalized C64 and Sinclair ZX logos.
DIY Machines shows off a really creative design for a wall shelving unit. Not only does it provide 12 illuminated cubbies for items like small plants or collectibles, but its light-up edges double as a colorful digital clock. To build one for yourself, you’ll need a 3D printer, plus the items listed on the project’s YouTube page.
There are places where you can get some really nice, professional business cards these days, but if you really want to stand out from the crowd, you need to do something extra special. 3D designer Stian Ervik Wahlvag (aka agepbiz) did just that, and made himself some custom cards that look like packaged toys.
Dogs love tennis balls. To celebrate this cherished relationship, architecture firm CallisonRTKL created a very special doghouse, covered with 1,019 tennis balls – each of which can be removed to play with. The 3D-printed doghouse was auctioned off to benefit the SPCA of Texas, but we’d love to see this sold in kit form.
One of the cooler LEGO parts out there is the stud shooter, a tiny weapon for minifigs that fires a single round stud. LEGO fan agepbiz decided to see if he could supersize the plaything into something humans could wield, and managed to pull it off with aplomb. He previously made a human-scale LEGO space blaster.
Roman Khramov of 5 min Minibricks shows us how to create a tiny diorama of a boat and ocean waves inside of a tea cup using 3D printing, paint, cotton, and resin. The base was created with a Snapmaker 3D printer, but it required craftsmanship and skill to bring the scene to life with such detail. (Thanks Niklaus!)
This mind-bending creation is a full color, 3D-printed spherical object that’s been layered with a full-color 360° panoramic image. If you don’t have a full color 3D printer handy, there are a couple of options for these on the market including Scandy Spheres and the less expensive Snapspheres.
Mojoptix’s nifty 3D-printed object works like a traditional sundial, casting a shadow as the sun moves overhead, but it displays the time using dot-matrix digits, thanks to some very clever engineering. You can buy a pre-printed version from 3D Expressions on Etsy, or download the STL files on Thingiverse if you’ve got a 3D printer.
Designed by Ben Liew, this bold writing instrument features a body with a slick open-weave design. The complex geometry is made possible using 3D printing technology, and the pen will be offered in resin or titanium, or as a glass nylon prototype, which doesn’t share the smooth feel of the production versions.
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.
