Escape from this dimension – well, in your mind – with Dave Dalton’s cool replica of Rick’s portal gun from Rick & Morty. Like other fan-made replicas, it has the green bulb and LED display, but it also projects an animation of the portal.
That made up word up there is actually in a research paper, thanks to the Carnegie Mellon University researchers who came up with a technique to make FDM 3D printers print strands of hair, fiber or bristles, without any hardware modification.
Back in April we checked out a 3D printed violin that looked more like a Predator’s weapon than a musical instrument. But 3D printing isn’t just about making new physical forms. The technology can be tuned for very practical purposes as well, as exhibited by violin maker Hovalin.
The railgun is one of the most popular sci-fi weapons, perhaps eclipsed only by the lightsaber and anything with lasers on it. Part of its appeal is that it’s based on real physics. It could exist, and it does exist!
We’ve featured a 3D printed Bulbasaur planter before, but that one’s no longer on sale. Fortunately, Etsy shop PrintAWorld has a similar product as well as an Oddish planter.
The Bulbasaur planter is made of ABS plastic.
Last month we featured the Dobot, a precise robotic arm that can plot, laser engrave and pick and place objects. But if you’re looking for something even more versatile, the Makerarm might be for you. It can also draw, use a laser head and assemble objects, but you can also use it as a 3D printer, a PCB fabricator, a soldering station and even a screwdriver.
One of the advantages of LED bulbs over incandescent ones is that they generate significantly less heat. Product designer David Graas capitalized on that benefit by creating lamps with 3D printed “bulbshades”, which are diffusers that sit directly on the LED bulb.
Electronics maker Rohm Semiconductor entertained attendees of this year’s CEATEC with flying origami cranes. Rohm made the cranes to promote its new microcontroller, the Lazurite Fly.
Aside from its paper body and the Lazurite Fly, the Orizuru crane has a carbon tube skeleton, 3D printed nylon motors, a radio receiver and a battery that lasts up to five minutes per charge.
A few months ago, we featured Instructables employee DJ aka Aleator777’s Apple II Watch. He recently shared another impressive retro watch, one that’s arguably more useful than the current Apple Watch. He calls it the Communicator Watch, because it’s also a GSM cell phone.
Attention 3D modelers! The 3D marketplace Pinshape and 3D design resource center Mold3D have launched a robot design contest. Create one or more 3D printable parts for their MakerTron robot and you could win a 3D printer and more.
A couple of months ago, we checked out Sergey Grishchenko’s DIY scale model of the Curiosity rover. Michael Larkin’s Moon One is a very similar remote-controlled rover, but he optimized it for agility, maneuverability and mischief.
Last March, the performing arts group Extant held a unique rendition of the novel Flatland. The installation was set in complete darkness inside a disused church. But the audience members were able to make their way around the set with the help of the Animotus, a haptic navigation device that points to the destination by changing its shape.
Redditor mrdeepimmersion wanted to apply for a game design job at Wizards of the Coast’s Dungeons & Dragons team. Thinking that his electrical and computer engineering background put him at a disadvantage, he decided to show off his creativity by making a 70lb.
Aside from the usual plastics and composites, we’ve seen 3D printers use food, sand, metal and even paper to make objects. MIT adds glass to that ever-growing list of materials with its Glass 3D Printing (G3DP) platform.
A new company called Cultivate3D has developed a large format 3D printer that won’t devour your budget. The Beast has a 470 x 435 x 690mm (~18.5 x 17.1 x 27.2″) build area in a single extruder setup, and can be equipped with up to four extruders for faster printing.
What’s better than a magic 8 ball? A magic 20 icosahedron. Adafruit and Phillip Burgess made a guide that shows us how to make a D20 that talks about the resulting roll.
The die’s accelerometer helps it figure out which face is up.
