world's first 3D printed metal gun successfully fires 50 bullets nov 08, 2013 world's first 3D printed metal gun successfully fires 50 bullets world’s first 3D printed metal gun successfully fires 50 rounds of bulletsall images courtesy solid concepts 3D printing service leader solid concepts has manufactured the world’s first 3D printed metal gun using a laser sintering process and powdered metals. the semi-automatic pistol is based off the design of a classic 1911 and has already successfully fired over 50 rounds of bullets without breaking. the fire-weapon is constructed with 33 17-4 stainless steel and inconel 625 components, and features a carbon-fiber filled nylon hand grip. ‘the whole concept of using a selective laser sintering process to 3D print a metal gun revolves around proving the reliability, accuracy and usability of metal 3D printing as functional prototypes and end use products,‘ says kent firestone, vice president of additive manufacturing at solid concepts. detail of the 3D printed .45 caliber pistol rodrigo caula I designboom
3D-Printed-Labyrinth-Totem.m4v The Printer That Can Print A 2,500 Square Foot House In 20 Hours. We have seen huge advancements in 3D printing. We’ve even seen oversized wrenches printed that measure 1.2 meters in length. Now, we can print an entire 2,500 sqft house in 20 hours. In the TED Talk video below, Behrokh Khoshnevis, a professor of Industrial & Systems Engineering at the University of Southern California (USC), demonstrates automated construction, using 3D printers to build an entire house in 20 hours. In manufacturing we use a process called CAD/CAM (computer-aided design / computer-aided manufacturing). 3D models are designed on a computer and then manufactured using CNC Machines or 3D printers. The design is manufactured into a physical object automatically, with instruction from 3D computer model to physical object without human interface. In this video, we see a prototype of a machine called ‘Contour Crafting’ Michael Cooney Michael Cooney, the founder of EngNet, worked as a project engineer for many years sourcing equipment.
Fractal Graph 4 Scientists build a low-cost, open-source 3-D metal printer OK, so maybe you aren't interested in making your own toys, cellphone cases, or glow-in-the-dark Christmas decorations. How about a brake drum? 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 Michigan Technological University's Joshua Pearce and his team could add hammers to that list. The detailed plans, software and firmware are all freely available and open-source, meaning anyone can use them to make their own metal 3D printer. Pearce is the first to admit that his new printer is a work in progress. Using under $1,500 worth of materials, including a small commercial MIG welder and an open-source microcontroller, Pearce's team built a 3D metal printer than can lay down thin layers of steel to form complex geometric objects.

Fractal Graph 3 3d print a building 1. Types of 3D printers (SLA, FDM, SLS and Z-printers) StereoLithogrAphy (SLA) The first 3d Printer, built in 1983 by Chuck Hull was using SLA technology to print with a photoplymer. Layer by layer, a liquid polymer is exposed to light from a low-power laser and hardens locally. It produces very accurate prints, theoretically capable of tolerances within 100 nm (0.0001 mm), smaller than visible light wavelength, because of the capacity of lasers to focus beams of only a few photons in diameter. Traditionally a very expensive technology using expensive polymers, recently it became affordable through the Formlab Form 1: Fused deposition modeling (FDM) A very popular technology developed in the 80s by Scott Crump and widely available today after the expiration of patents when the large Rep-Rap open-source community started to develop affordable machines using this technology. Selective laser sintering (SLS) and other variations (DMLS, SHS, SLM, EBM) Plaster-bed printing (PP) 2. 1. 2. 3. Like this:
Octahedron Fractal Graph DIY BioPrinter, une imprimante 3D biologique à la maison « MakingSociety Le hackerspace BioCurious vient de mettre en ligne des instructions pas-à-pas pour fabriquer son imprimante 3D biologique à la maison. Toutes les étapes sont partagées librement sur le site Instructables. Patrick D'haeseleer est un scientifique amateur américain d'origine belge et membre actif du hackerspace BioCurious, un espace collectif spécialisé en hacking biologique basé à Sunnyvale en Californie. Le DIY BioPrinter de BioCurious. Cette machine permet d'imprimer des organismes vivants. Le fonctionnement du BioPrinter DIY est somme toute très simple. Cette technique est déjà utilisée dans le champ médical. Il a notamment expliqué sa démarche lors de deux conférences TED spectaculaires. L'entreprise Organovo s'est de son côté spécialisée dans la fabrication et la commercialisation de ces imprimantes 3D. Crédit : Organovo© Le BioPrinter DIY de BioCurious fonctionne de façon très similaire, et il est entièrement réalisable à la maison pour un peu plus de 100 euros.
Hopf Fibration 1 Hypr3D Developing Sierpinski arrowhead curve Could This Be the 3D-Printed Cast of the Future? Jul 7, 2013 Jake Evill wants to use 3D printing to revolutionize the way we treat fractured bones. Instead of the typical bulky, itchy and smelly plaster or fiberglass casts we use today; Evill is proposing a custom, 3D-printed, lightweight, ventilated, thin, recyclable and washable design. Jake is a recent graduate from the Architecture and design faculty at the Victoria University of Wellington. He majored in media design with a minor in industrial design. In a recent interview with Dezeen, Jake explains: “At the moment, 3D printing of the cast takes around three hours whereas a plaster cast is three to nine minutes, but requires 24-72 hours to be fully set. The project was done in collaboration with the University’s orthopedic department. [via Dezeen]
