3D Printed MakerBot

June 5, 2010 by 12 Comments

[Webca] has made a 3D printed MakerBot with his MakerBot. Using five pounds of plastic, the design replaces all of the plywood used to create a regular MakerBot. This complements the existing designs for the 3D printed extruders, dinos, and other parts already on Thingiverse. An interesting mile marker in the history of 3D printing. We might make one after we make a Mendel and tons of Hack a Day Badges. We also look forward to improvements people will contribute to the design such as using less plastic or a parameterized design to make a really big (or small) MakerBot.

Open3DP Looks At 3D Printing In Common Materials

May 11, 2010 by 11 Comments

[Buddy Smith] sent us a link to Open3DP which he calls “REAL 3d printing hacks”. Open3DP showcases the projects of the Solheim Rapid Prototyping Laboratory at the University of Washington. They’re working on 3D printing in materials that can be commonly acquired and to that end they publish recipes for powder printing in materials such as sugar, ceramic, and glass. Take a look through their archives. We found the post on microwave kilns interesting, as well as the writeup about Shapeways glass printing which is seen above. We’ve also embedded a short video on Open3DP’s work after the break.

Update: [Mark Ganter] dropped us a line to clarify that Open3DP was the first to develop printable glass about a year ago, called Vitraglyphic. They’ll also be presenting papers at Rapid2010 and announcing a new printable material.

CES Update: CES Badges

January 9, 2010 by 8 Comments

In a previous post we had given one of our badges out to [Bre Pettis] at the MakerBot booth. We have been called the “Skull Guys” around CES and were stopped multiple times by people that did not know of this site. [Bre] got an extra of the size we are wearing around. [Leo Laporte] received the very first prototype which he promptly placed in his mouth. The badges are made from natural ABS plastic in [Devlin]’s CupCake CNC machine. There will be a post-CES follow-up with the release of the STL files to make the badge on Thingiverse as well as a step-by-step breakdown of the build process.

Printing Circuits On The RepRap

[Rhys Jones] has been working with the RepRap team to develop a way to print circuit boards. The machine first prints the plastic substrate with channels for the metal to be deposited into. They adapted their pinch wheel feeder to work with solid core solder (flux creates a mess). The extruded solder’s specific heat isn’t hot enough to melt the plastic. They made a video (embedded below) of their test piece: an optical endstop. The team has also been experimenting with decoupling the feed mechanism from the extruder.

3D Printing At Home

We’ve seen a lot of 3d printing lately, with the RepRap and Cupcake, both the fused deposition modeling type. We don’t often see the Inkjet method. This is a great example of one, built in someones home. Instead of laying down layers of molten plastic, he uses the inkjet system to deposit glue like substances into layers of plaster. This project is much higher resolution than the other two, as you can see in the video of it making an RC engine case below. He is currently rebuilding it to be even better and larger.

CupCake CNC Kit

The CupCake CNC Kit is the flagship product of MakerBot industries, a joint venture between [Bre Pettis] and [Zach Hoeken]. At $750, it comes with all the motors, belts, body pieces, bearings, belts, and other pieces to assemble it. You could be printing your own 3d objects in a matter of hours with this. 3D printers with only slightly larger capacities can run thousands of dollars. The only advantage to some of the commercial products might be resolution. They don’t give much as far as technical data as the unit isn’t available yet. They should start Shipping before April 15th, so they can’t be far off. This could possibly be a competitor for the RepRap. Since RepRap doesn’t offer a complete kit, we’ll have to speculate. We’ve seen estimates from $500 to $1000 to build one.
