Prints In Space (Said In “Pigs In Space” Voice)

3D Printing on Earth is soooo last year. Recently, NASA has sent a 3D Printer to the International Space Station in order to test printing capability in space. The agency’s ultimate goal is to have a means to make parts and tools for astronauts that are far away from earth.

So, why should NASA have all of the extra-terrestrial printing fun? Three 15 year-olds thought that same thing and decided to build their own space printer. It’s goal, however, is a bit different from the one on the ISS. This printer is made to print on other celestial bodies such as the moon or Mars, not in a space station. The students call their project the DELTA 3 and as its name implies, is a delta-style printer and that’s where all similarities with conventional printers end. This printer has tank tracks so that it can maneuver itself around the planet. There is no print bed. The printer prints directly to the surface of which it is resting on. The frame is open at the front of the printer so that it can back up leaving a free-standing print in its wake. It certainly beats the hot-glue versions seen before and we think this is the Automated Build Platform of the future, today!

The DELTA 3’s electronic controls are also quite different from the norm. There is a Lego EV3 controller that is responsible for navigating the printer around obstacles to find a suitable print area. Once a location has been picked out, the EV3 triggers the standard Arduino Mega/RAMPS combo to coordinate the printing.

The young creators brought their DELTA 3 to the World Robot Olympiad just last month. They came in 4th in their division.




Hackaday Links: July 27, 2014


Taking apart printers to salvage their motors and rods is a common occurrence in hacker circles, but how about salvaging the electronics? A lot of printers come with WiFi modules, and these can be repurposed as USB WiFi dongles. Tools required? And old printer, 3.3 V regulator, and a USB cable. Couldn’t be simpler.

The Raspberry Pi has a connector for a webcam, and it’s a very good solution if you need a programmable IP webcam with GPIOs. How about four cameras?. This Indiegogo is for a four-port camera connector for the Raspi. Someone has a use for this, we’re sure.

The one flexible funding campaign that isn’t a scam. [Kyle] maintains most of the software defined radio stack for Arch Linux, and he’s looking for some funds to improve his work. Yes, it’s basically a ‘fund my life’ crowdfunding campaign, but you’re funding someone to work full-time on open source software.

Calibration tools for Delta 3D printers. It’s just a few tools that speed up calibration, made for MATLAB and Octave.

[Oona] is doing her usual, ‘lets look at everything radio’ thing again, and has a plan to map microwave relay links. If you’ve ever seen a dish or other highly directional antenna on top of a cell phone tower, you’ve seen this sort of thing before. [Oona] is planning on mapping them by flying a quadcopter around, extracting the video and GPS data, and figuring out where all the other microwave links are.

PowerPoint presentations for the Raspberry Pi and BeagleBone Black. Yes, PowerPoint presentations are the tool of the devil and the leading cause of death for astronauts*, but someone should find this useful.

* Yes, PowerPoint presentations are the leading cause of death for astronauts. The root cause of the Columbia disaster was organizational factors that neglected engineer’s requests to use DOD space assets to inspect the wing, after which they could have been rescued. These are organizational factors were, at least in part, caused by PowerPoint.

Challenger was the same story, and although PowerPoint didn’t exist in 1986, “bulletized thinking” in engineering reports was cited as a major factor in the disaster. If “bulletized thinking” doesn’t perfectly describe PowerPoint, I don’t know what does.

As far as PowerPoint being the leading cause of death for astronauts, 14 died on two shuttles, while a total of 30 astronauts died either in training or in flight.
