Projects Students built a device with a series of 15 pendulums in a row, each one slightly longer than its neighbor, then set them in motion and filmed the result. The resulting patterns in the short video below are fascinating to watch. Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and random motion.
Open Source Wedding Rings [update 1][update 2] I lost my wife’s wedding band a few years ago. She handed it to me while I was driving and asked me to take it to a jeweler to get it hammered back “in round”. Blender Tutorial: Blender 3D printing tutorial This tutorial was made for Blender users with an interest in 3D printing. It covers the essential information for taking your 3D model and turning it into a 3D object using the free CAD software. Through this tutorial, you will learn some of the best practices for modeling, correcting and exporting a 3D file for 3D printing with Blender 2.7. Specifically this tutorial covers the following points:
Online 3D Converter Convert 3D models between file formats (i.e. FBX to OBJ or OBJ to STL for 3D printing, DAE to JSON for use with WebGL, ..). Supported input file formats include 3DS, FBX, Blender, OBJ, DXF, LWO, STL, PLY and more than 25 others. Output formats include Collada, 3DS, X, OBJ, PLY, STL (Text and Binary), JSON (Assimp2Json) and more. i love sketch Seok-Hyung Bae, Ravin Balakrishnan, and Karan Singh are about to present “ILoveSketch: As-natural-as-possible sketching system for creating 3D curve models,” ACM Symposium on User Interface Software and Technology 2008 (Monterey, CA, USA, October 19-22, 2008) ILOVESKETCH is a 3D curve sketching system that captures some of the affordances of pen and paper for professional designers, allowing them to iterate directly on concept 3D curve models. The system coherently integrates existing techniques of sketch-based interaction with a number of novel and enhanced features. Novel contributions of the system include automatic view rotation to improve curve sketchability, an axis widget for sketch surface selection, and implicitly inferred changes between sketching techniques. We also improve on a number of existing ideas such as a virtual sketchbook, simplified 2D and 3D view navigation, multi-stroke NURBS curve creation, and a cohesive gesture vocabulary.

Most Likely a Scam by Sterling D. Allan Pure Energy Systems News Oct. 26, 2010 Mazzo di Fiori & the Next Generation 3D Printer by Joshua Harker I am an artist. I have become known for my pioneering work in the 3D printed medium & have a professional history in product invention/design & development. My art is about pushing the limits of form... an exploration into what can be made & how to accomplish it. My venture into this project is a direct extension of that. For the last 18 months I've been developing a new 3D printing technology to usher in the next generation of the 3D printing revolution in terms of quality, capability, cost, access, & ease of use. This is a completely new approach & not another FDM/RepRap or DLP project.
Blender 3D Modeling Software You can do 3D Open Source modelling and animation with Blender software. Blender 3D Modeling Software screenshot About Blender software This free CAD software was published by NaN (Not a Number). Originally, Tom Roosendaal, the cofounder of NeoGeo, the largest 3D animation studio in the Netherlands, was behind creating this CAD software. Online SVG image converter Online image converter This free online image converter lets you convert your images to the Scalable Vector Graphics (SVG) format (experimental). You can either upload a file or provide a URL to an image. Additionally you can select digital effects to enhance the image. If you convert from raster images like PNG or JPG, this SVG converter will convert your shapes and objects to black and white vector graphics that are scalable without any loss in quality.
Spatial and Dassault Put 3D CAD on the Cloud. What it All Means. - SolidSmack At the beginning of the year I predicted a move of 3D apps toward the cloud. Anyone could have guessed that though. SolidWorks showed-off the cross-platform possibilities and Autodesk put AutoCAD on the cloud. A Simple, Low-Cost Conductive Composite Material for 3D Printing of Electronic Sensors 3D printing technology can produce complex objects directly from computer aided digital designs. The technology has traditionally been used by large companies to produce fit and form concept prototypes (‘rapid prototyping’) before production. In recent years however there has been a move to adopt the technology as full-scale manufacturing solution. The advent of low-cost, desktop 3D printers such as the RepRap and Fab@Home has meant a wider user base are now able to have access to desktop manufacturing platforms enabling them to produce highly customised products for personal use and sale. This uptake in usage has been coupled with a demand for printing technology and materials able to print functional elements such as electronic sensors.
