MIT Develops Inkjet-Style 3D Printer That Uses 10 Different Materials At Once

Lucas123 writes: Researchers at MIT have been able to build a printer with uses 10 different photosensitive polymers to create a myriad of objects, and they were able to build it using off-the-shelf commodity parts for around $7,000. The MultiFab 3D printer works by mixing together microscopic droplets of photopolymers that are then extruded through inkjet printheads similar to those in office printers. A UV light then hardens the polymers layer by layer. Perhaps even more remarkable than the list of materials it can use is the MultiFab 3D printer's ability to self-calibrate and self-correct during a print job (PDF). The printer has an integrated machine vision system that automatically readjusts the printer head if errors occur, rectifying the build before a problem ruins the object; that means print jobs that run into errors don't need to be cancelled and materials wasted. The researchers said they can foresee an array of applications for the MultiFab 3D in consumer electronics, microsensing, medical imaging and telecommunications, among other things.

    At some point all those old grumpy men who mock the progress of technology are going to have to pick some other up-and-coming technology to mock since it's clear that 3D printing is going to keep improving.

      Old grumpy men don't mock the progress of technology, they mock the over hyping of a technology that has been around for 40 year. We are still developing manufacturing technology on all fronts, yet only see 3d printing stories. Why do non grumpy young men hate on manufacturing technology that isn't 3d printing?

    This will become much more interesting with full 3D printers that can self-replicate. How many copies down the road until enough errors crop up that it stops working "good enough" and starts printing out Bitch Printies.
