Fab@Home was the first multi-material 3D printer available to the public, and one of the first two open-source DIY 3D printers (the other one being the RepRap). Up until 2005, all 3D printers were industrial scale, expensive and proprietary. The high cost and closed nature of the 3D printing industry at the time limited the accessibility of the technology to the masses, the range of materials that could be used and the level of exploration that could be done by end-users. The goal of the Fab@Home project was to change this situation by creating a versatile, low-cost, open and “hackable” printer to accelerate technology innovation and its migration into the consumer and Maker space. Since its open-source release in 2006,〔 hundreds of Fab@Home 3D printers were built across the world,〔 and its design elements could be found in many later DIY printers, most notably the Makerbot Replicator. The printer’s multiple syringe-based deposition method allowed for some of the first multi-material prints including direct fabrication of active batteries, actuators, and sensors, as well as esoteric materials for bioprinting and food printing.〔 The project was closed in 2012 when it was clear that the project’s goal was achieved and distribution of DIY and consumer printers outpaced the sales of industrial printers for the first time.〔 ==History== The project was led by students at Cornell University's department of Mechanical & Aerospace Engineering. The effort was inspired by the history of the Altair 8800, one of the first DIY home computer kits released in 1975. The Altair 8800 is largely credited with triggering the home computing revolution and the transition from the industrial mainframe to the consumer desktop, by making a low-cost, open and “hackable” computer accessible to home enthusiasts for the first time. The goal of the Fab@Home project was to accomplish a similar effect in the 3D printing space. The project was one of the first larger scale cases that applied the open source development model to physical devices, a process that later became known as Open Source Hardware. Early versions of the device were produced and refined in the lab. The first official release of the Fab@Home model 1 coincided with a presentation at the Solid Freeform Fabrication conference in 2006.〔 After its first release, undergraduate and graduate students at Cornell and other locations joined the team and developed an improved version, later released as the Fab@Home Model 2.〔 The main improvements included easier assembly, no soldering, and fewer parts. The team then expanded and developed the model 3. One important variation of Fab@Home was the Fab@School project, which explored the use of 3D printers suitable for classroom use in elementary grades. Fab@School printers could print with benign materials such as Play-Doh and included a safety enclosure. The project received wide media attention in its initial years, bringing 3D printing from a relatively obscure technology to broader attention. Notable recognition was the Popular Mechanics Breakthrough award〔 and the Rapid Prototyping Journal best paper of the year award. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fab@Home」の詳細全文を読む スポンサード リンク
