[Deviant Ollam], lockpicker and beverage cooling contest host, was recently in Vienna, presumably for DeepSec. While there, he stopped by the Metalab hackerspace and checked out their RepRap rapid prototyping machine. You can see video of his visit above. He had them construct a custom fitted cover for the flash of his point and shoot camera. That’s what we love about rapid prototyping. Many of the projects we cover here solve a particular problem, but would never be considered commercially viable enough to put into production. With the availability of rapid prototyping increasing, hackers can start moving toward producing even more complex objects specific to their needs with a finish closer to commercial products.

Lasercut RepRap Kit

October 19, 2008 by Eliot 19 Comments

The RepRap is a self-copying 3D printer. The project has published plans for creating a lasercut acrylic version of the device. They call it a RepStrap since once assembled it could produce printed plastic versions of the machine components, bootstrapping true RepRaps. The plans are available for Ponoko an on-demand product service, and it would cost ~$380 if you used their service. The plans are free, so you could get them manufactured by other means. [vik] is still putting together the assembly instructions. He hopes to have an all inclusive electronics kit at some point too. This is another great step towards putting desktop manufacturing within reach of everyone.

Sanguino ATmega644P Board

October 5, 2008 by Jason Rollette 23 Comments

The RepRap project, which is a printer that can make components using rapid prototyping technology, and it is designed so that it can eventually self replicate. Has released a new breakout board for the Sanguino that provides access to all the pins as screw terminals. The Sanguino is an Arduino compatible board based on the ATmega644P chip. You can populate the full board with all the components and have a fully functional single board. You could populate only the screw terminals and plug your Sanguino, and use it as a breakout board as well. The board design is released on Google Code.

HOPE 2008: Community Fabrication

July 19, 2008 by Eliot 4 Comments

Today at The Last HOPE, [Far McKon] from Philadelphia’s Hacktory presented on community fabrication. Over the last few years we’ve seen a lot of different accessible rapid prototyping machines created. There’s the RepRap, a fabrication machine that has achieved self replication; our friends at Metalab have gotten their own version of the machine running too. The Hacktory has recently acquired a Fab@home machine. Fab@home hopes to make manufacturing using multiple materials accessible to home users. Multiple materials means people have constructed objects that vary from embedded circuits to hors d’oeuvres. We can’t talk about edible prototyping without bringing up the CandyFab machine, which fuses sugar. The Hacktory has enjoyed their machine so far, but have found the learning curve fairly difficult. While it’s great to see the cost of rapid prototyping dropping, we’ll be much happier when the ease of use improves.

Turn Any Motor Into A Servo With RepRaps New Board

July 16, 2008 by Will O'Brien 20 Comments

[Zach] just let us know about a new board that’s available from the RepRap project. It uses an AS5040 magnetic rotary encoder to measure the absolute position of the rotor of whatever motor you’re using. This is actually pretty damn exciting. Powerful servo motors are expensive, but with one of these, you can use whatever motor you can get your hands on. Big DC motors are cheap, but even used DC servo motors expensive. Best of all, the encoder is open source and you can score a kit version for a paltry $20. Now we can make that 8 horse power servo…

FABR: Another 3d Printing Project

July 13, 2008 by Will O'Brien 7 Comments

[Lou]’s been working on his own 3d printer: fabr. We find it appealing because the entry cost is quit a bit lower than something like the reprap. 80/20 isn’t that cheap, but you don’t need a large commercial laser cutter to build the chassis. The steppers he used appear to be inexpensive ones that can be salvaged from dot matrix printer. To drive it, he’s working on a custom microstepping board and hopes to eventually develop an Arduino shield to control the stepper drivers. That’s right, it’ll get an Arudino to act as the CNC control interface.

RepRap Universal Constructor Achieves Self-replication

June 4, 2008 by Juan Aguilar 14 Comments

RepRap, the self-replicating universal constructor has had our attention since it first started spitting out globs of shapeless goo, but its speculative potential turned in a real benchmark recently when a RepRap machine made parts for an identical machine in a few hours (a child, in other words), then the second RepRap successfully made parts for a third or grandchild machine.

RepRap does not fully assemble copies of itself, but produces the 3D-printed plastic components necessary to assemble another copy. It has also successfully produced other plastic goods like sandals and coat hooks. [Dr. Adrian Bower] is the leader of the RepRap team, and he will be exhibiting its capabilities at this week’s Cheltenham Science Festival.
