A Cornell University Professor along with his student creates a 3D Printer for $2400.
A cheap self-assembly device capable of fabricating 3D objects has been developed by US researchers. They hope the machine could kick start a revolution in home fabrication – or "rapid prototyping" – just as early computer kits sparked an explosion in home computing.
Rapid prototyping machines are already used by designers, engineers and scientists to create one-off mechanical parts and models. These create objects by depositing layer upon layer of liquid or powdered material. These machines typically cost from $20,000 to $1.5 million, says Hod Lipson from Cornell University, US, who launched the Fab@Home project with PhD student Evan Malone in October 2006.
The 3D Printer costs only $2400 and is like a Microwave machine size. Hod Lipson says, that the designers in industries can buy this Printer Kit and glue them and assemble together quickly. The machine is then connected to the computer and you can control this 3D Printer like the regular printer. It then creates objects layer-by-layer by squeezing material from a mechanically-controlled syringe. A 3D object created by this machine is shown in the picture. The movie below shows the 3D Machine manufacturing a Silicone bulb. The Mechanical designers would love this machine to quickly produce prototypes and also at a low cost. Not only they can use Silicone, plaster, but also Chocolate and icing. So its applications seems to be unlimited.
