Fresh hacks every day
[Quentin Harley] must really have wanted to test his snuff when it comes to mechanical engineering. He’s been hard at work for a couple of years now designing his own SCARA arm 3D printer. That link leads to a recent summary article in which he shows off the build as seen above. It’s not fully functional yet, but he’s … Read the rest
Here is yet another way to get into the holiday spirit at your local Hackerspace (or at home if you’re happen to have your own 3D printer). [Ralph Holleis] wrote in to show off his 3D printed Christmas cookies. The majority of the info on this project comes from the video embedded after the break. The extruder head he’s … Read the rest
Here’s the situation: a kilogram of 3D printer filament costs about $50. A kilogram of plastic pellets costs less than a tenth of that. Does anyone have a solution to this problem?
For years now, the general consensus was making your own 3D printer filament at home was nigh impossible, dealing with temperatures, pressures, and tolerances that home-built machines simply … Read the rest
There’s one problem with the popularity of plastic-extruding 3D printers such as the RepRap and Makerbot; since they’ve become so popular, the price of plastic filament has skyrocketed over the past few years. Without a way to produce filament at a hackerspace or home lab, the price of 3D printed objects will remain fairly high. Project Spaghetti hopes to rectify … Read the rest
Wow, building a precision 3d printer is amazingly easy if you can get your hands on an industrial-quality robot arm. [Dane] wrote in to tell us about this huge extruder printer made from an ’80s-era SCARA robot arm. It is capable of printing objects as large as 25″x12″x6.5″.
This 190 pound beast was acquired during a lab clean out. It … Read the rest
3D printers such as the RepRap and Makerbot turn spools of plastic filament into just about any object imaginable. There’s a problem though: this filament costs about $40 a kilogram, and raw plastic pellets cost about 1/10th of that. Obviously, there’s a lot of room for improvement. The folks at Inventables are throwing $40,000 at the problem in a contest … Read the rest
Chocolate has got to be one of the worst choices as a printing medium. It’s extremely fussy when it comes to melting point, and even in the right state the flow of the material is not going to play nicely with high-resolution designs. With this in mind, we applaud the progress the student team from Carnegie Mellon University has made … Read the rest
