Kidraulic open source 3D printable toy modules

KidRaulic is an innovative open-source toy project developed by Idan Zilzer in which anyone with a 3D printer can download the basic building blocks and easily design and create with them any toy you can imagine. It uses syringes to change air pressure and move parts of a toy.





Here is video of it in action:



You can download the files for it here:

Make your own aluminum frame Ultimaker 2 clone

Jason developed Ultimaker 2 clone made with aluminum extrusion frame and 3d printed parts. According to his posts it work very well.

He describes it as:
This is not The Greatest UM2 Clone, no.
This is just a tribute.
This project began as a fun way to learn AutoDesk Fusion 360. I started by importing the entire Solidworks CAD file into a new Fusion 360 project, dropped the frame (walls) from the printer, built 20x20 Misumi aluminum extrusions to wrap the printer guts and then worked to build brackets to support all the parts that previously attached to the frame.
I've been printing nonstop on this new printer with the same precision and quality as my real UM2. In fact, I can use the same GCODE in either machine with identical results.

GrabCAD CubeSat Challenge

Here is a great contest for all you guys interested in 3d printed satellites and space. It has some great awards also.

One of the contest entries. 

The contest is organized by Stratasys, MakerBot and GrabCAD.

About This Challenge

The goal of this challenge is to design a small satellite frame optimized for additive manufacturing. By using the benefits of design for additive manufacturing (DFAM) principles:
  • Mass distributions and materials can be rethought to minimize weight 
  • Part count can be reduced to improve producibility 
and ultimately, cost can be reduced.

Awards for TOP 10 places:

1st Place

- $2,500 cash
- Your design printed by Stratasys Direct Manufacturing
- Makerbot® Replicator® and material pack.
- Featured story in Stratasys online communication and use of your design as an example part in Stratasys trade show and conference appearances.


2nd Place

- $1,000 cash
- Your design printed by Stratasys Direct Manufacturing
- Makerbot® Replicator® and material pack


3rd Place

- $500 cash
- Makerbot® Replicator® and material pack.


4th - 10th Place

- $100 cash
- Makerbot T-Shirt
- 3D Printed Sample Part

also don't forget about NASA 3d printed habitat contest:


Good luck people! 


So, WHAT is 3d printing?

... well it is different things to different people ...




























Do you have similar experiences? :-)

DIY digitizer with detailed construction guide

Nikolaj Møbius from Fablab RUC developed a simple and cheap DIY digitizer 3d scanner that can record points in a physical space and convert them into a 2D vector drawing for laser cutting or 3D printing.
It is made with three rotary encoders and gets a points measures controlled by Arduino. Since it currently does only measures more suitable for 2D capture it is ideal for CNC or laser cutting with very good results.
Since the software is in early development phase we can expect better 3d scanning or 3d point cloud capture soon.





Check out the project homepage with very detailed build guide and software:

http://fablab.ruc.dk/diy-digitizer/

It looks very easy to build even for the beginners.

Here is the description of current limitations:
So far the system is designed to record a 2D surface and convert it into a PDF vector file. The Z axis is simply ignored in the output. Since the system actually records in a 3D space it is possible to export a 3D object for post processing. This is mainly a matter of implementing a another export method.
However, since the arm is not able to reach around an object in a 3D space it will not be possible to record all the points necessary to make a full 3D object (Update: In the source files we have a version with a rotating platform now). One possible workaround would be to implement a rotating base which would enable the arm to approach the object from all sides. Further, the software is only a usable prototype, but could be evolved into a much more solid tool.
I like the plywood frame arm!

PS:

I was wondering how to convert point cloud in some solid mesh by using free software and I found this tutorial with Meshlab:



DIY 3d printed hand exoskeleton

The first thing that came to my mind was: CAN YOU PUT SOME MOTORS ON IT AND GET SUPERSTRONG? The project was developed by 3DPrintIt.com.au from Australia (two words: MAD MAX) ...

Testing 3D printed DIY arrowheads

Here you can see a video of a test featuring DIY 3d printed arrowheads and their effect on 3d printed chain mail and fruit :-) While 3d printed compound bows seem functional, these arrowheads seem completely useless.




Two arrowheads were tested:


NASA 3D Printed Habitat Competition

Here is a great competition with some big prizes. NASA wants you to help them explore and inhabit the space with help of 3d printing! I wish you the best of luck if you are going to compete!










Competition details from the NASA page:
NASA and the National Additive Manufacturing Innovation Institute, known as America Makes, are holding a new $2.25 million competition to design and build a 3-D printed habitat for deep space exploration, including the agency’s journey to Mars.

The multi-phase 3-D Printed Habitat Challenge, part of NASA's Centennial Challenges program, is designed to advance the additive construction technology needed to create sustainable housing solutions for Earth and beyond.

The first phase of the competition runs through Sept. 27. This phase, a design competition, calls on participants to develop state-of-the-art architectural concepts that take advantage of the unique capabilities 3-D printing offers. The top 30 submissions will be judged and a prize purse of $50,000 will be awarded at the 2015 World Maker Faire in New York.

The second phase of the competition is divided into two levels. The Structural Member Competition (Level 1) focuses on the fabrication technologies needed to manufacture structural components from a combination of indigenous materials and recyclables, or indigenous materials alone. The On-Site Habitat Competition (Level 2) challenges competitors to fabricate full-scale habitats using indigenous materials or indigenous materials combined with recyclables. Both levels open for registration Sept. 26, and each carries a $1.1 million prize.
