Turn Your Plastic Recyclables Into 3D Printing Spools With Filabot Source: Filabot 3D printers are getting cooler every day, but there’s one component integral to 3D printing that normally gets overlooked – that is, until you have to pay for it. As many 3D hobbyists have no doubt discovered, the one time cost of the printer can be quickly dwarfed by feeding it spool after spool of raw plastic. At $40 or more per spool, an avid hobbyist can see his or her enthusiasm rapidly diminished. Maybe Filabot won’t revolutionize how 3D printing is done, but how often it is done. Filabot is a 3D plastic extrusion system that takes all kinds of recyclable plastic – milk jugs, soda, detergent and shampoo bottles – and turns them into raw material for 3D printing creativity. Not only will your household recyclables now appear as treasure troves of cheap and virtually endless supply of 3D printing plastic, all those projects that didn’t print right, cracked, or just didn’t turn out the way you thought it would can now be given a second chance at greatness.

DIY Stereolithography 3D Printer ‘Anti-Gravity’ 3D Printer Uses Strands to Sculpt Shapes on Any Surface 3D printers build objects by cross-section, one layer at a time from the ground up—gravity is a limiting factor. But what if it wasn’t? Using proprietary 3D printing materials, Petr Novikov and Saša Jokić say their Mataerial 3D printing system is gravity independent. The duo’s method allows a robotic arm to print objects on floors, walls, ceilings—smooth and uneven surfaces. Novikov and Jokić invented their system (patent pending) in collaboration with the Institute for Advanced Architecture of Catalonia. In contrast to the 3Doodler, Novikov and Jokić’s system is a software-controlled 3D printer. Why is this an improvement on current tech? Novikov and Jokić say, "This method gives us a flexibility to create truly natural objects by making 3D curves instead of 2D layers. Whether the system can print a wide variety of shapes isn't shown in the video. But the concept is cool, and the tech will likely improve. Image Credit: Mataerial

Build a Laser 3D Printer - Stereolithography at Home Here is how to make a Stereolithography 3D Printer. It is still a bit of a work in progress but so far it is working pretty well. This is mainly an experiment which started as a Delta Robot Stereolithography Printer but ended as a more traditional Cartesian Stereolithography Printer. "I'll be honest, we're throwing science at the walls here to see what sticks. Stereolithography (SL or SLA from Stereolithography Apparatus) is an additive manufacturing process using a vat of liquid UV-curable photopolymer "resin" and a UV laser to build parts one layer at a time. I have wanted a 3D Printer for a while now and there are some very reasonably priced kits available like the Makerbot, Ultimaker and the RepRap project. I decided to enter this in the Epilog Challenge Contest because I could really use a laser cutter :-) I also have some ideas how to redesign this project, for creation on a laser cutter. This project is Open Source Hardware.

3D printer makes a teddy bear with needle and thread - tech - 15 May 2014 FROM aircraft to houses and even guns, just about anything can be 3D printed – as long as it's not soft and squishy. Now the repertoire is about to get a lot more cuddly. The first 3D printer that can churn out soft objects made its debut last month at the Computer Human Interaction conference in Toronto, Canada. "The things that we hold close to our body, we would like them to be soft," says Scott Hudson at Carnegie Mellon University in Pittsburgh, Pennsylvania, who led the team that devised the printer. Initially, the machine could only work with melted plastic. To go beyond making teddy bears, the printer must be able to combine yarn with other types of material. The team is also experimenting with ways to embed electronics inside the bears without puncturing the circuitry or breaking the print needles. The soft printer is an great example of how far such machines have come, says Stephen Ervin of the Harvard University Fabrication Laboratory. More From New Scientist More from the web

3D printed replicas of people and pets from Captured Dimensions I met Jordan Williams at the Inside 3D Printing Conference and Expo. When I asked him what he did he pulled out a tablet and showed me this: That’s him holding a 3D printed bust of himself. Jordan runs a startup called Captured Dimensions and he just revamped the website, so we exchanged a few emails about the company. Jordan: We make our models of living subjects using the process of Photogrammetry. 3DP: That sounds expensive. Jordan: There was a great deal of trial and error throughout the initial phases of our setup. 3DP: What print services do you use? Jordan: Throughout development, we have sourced prints through several providers such as Shapeways, Sculpteo, local companies, etc. The photogrammetry method that Jordan uses takes hi-res pictures from 64 (and rising) angles at the same time and then stitches them all together to create a photorealistic 3D model.

Scientists build a low-cost, open-source 3-D metal printer -- ScienceDaily Until now, 3D printing has been a polymer affair, with most people in the maker community using the machines to make all manner of plastic consumer goods, from tent stakes to chess sets. A new low-cost 3D printer developed by Joshua Pearce and his team could add hammers to that list. A new low-cost 3D printer could add hammers to that list. Joshua Pearce is not one for understatement. His new book, published by Elsevier, is a step-by-step DIY guide for making lab equipment. In keeping with the open-source concept, parts of "Open-Source Lab: How to Build Your Own Hardware and Reduce Research Costs," will be freely available at different times on the Elsevier Store. Pearce, an associate professor at Michigan Technological University, began printing out lab equipment in earnest after a seminal moment, when he priced a lab jack at $1,000. Pearce hasn't looked back. Saving money is just the half of it.
