Breakthrough in 3D-printing? MIT unveils device molding 10 materials at once
The name is because it can use an unusually large number of materials at the same time during the manufacturing process-other existing ones
The printer can only use three at a time.

At the 13 SIGGRAPH 2015 meeting, the researchers stressed that MultiFab is much cheaper while providing \"better\" product quality.
The invention is more than the traditional 3-
3D printer, due to 3D-
The team developed scanning software called \"computer vision\" for the device.
The study was published in the SIGGRAPH 2015 record and also in the CSAIL paper at MIT.

\"A large part of the ability to reduce costs is 3-
D scan module, \"Javier Ramos, CSAIL engineer and co-engineer, MIT
Wired quoted the author of the study as saying.
\"The more expensive printer has this mechanical system that can scan each layer and make sure it\'s flat and laid out correctly.
Considering that we are using a machine vision system, we do not need extreme mechanical tolerances for this mechanismcontact.
\"It will scan and correct the layers, so we don\'t need these very expensive mechanical parts,\" he added . \".
\"The scanner we developed solved some high
Very high level problem with resolution, ability to scan large area quickly and then be able to scan transparent or translucent material.
\"These are very hard-to-scan materials in history,\" Ramos said . \".
The special rewards promised by developers are much simpler. part printing.
According to the MIT team, it will be possible to plug specific components-including complex components such as sensors and circuits-directly into the printer.
The machine will then incorporate the parts into the final product by identifying them and continuing to print around them.
MultiFab is a computer from the center, 3D-
The scanner and the printer itself.
The computer keeps receiving 3D-
Scan from a contactless \"machine vision\" scanner with a resolution of 40 microns or less than half the width of human hair.
The machine compares each print layer to the scan and detects errors that produce what the researchers call a \"correction mask.
\"This software technology makes it unnecessary for users to make all corrections themselves.
It also allows the printer to work without the expensive mechanical systems traditionally installed in these devices to help the user do a good jobtuning.
\"Now, the 3D printer focuses on printing forms and objects for the prototype, but the Holy Grail is to print out the full-featured things from the printer,\" Ramos said. \"combine multiple materials with multiple performances . \"
\"Through MultiFab, we combine these two worlds of traditional manufacturing with 3D printing, adding:\" We can make a series of new objects that we can\'t make at the moment . \".
The original software is low in combination-cost off-the-
The shelf assembly being developed allows MultiFab to enter at a relatively \"cheap\" price of $7,000.
According to the MIT paper, the potential cost of similar objects is as high as $250,000.
Scientists have managed to make a wide variety of objects, from optical and LED lenses and fabrics to optical fiber bundles and complex elements. materials.
They also created a plastic bracket for a metal blade and a perfect plastic holder
Print the size of the box around the smartphone and put it directly into the printer.
However, the device has its limitations.
It\'s quite slow: It took almost a day and a half to print a small model of a multi-color tire with MultiFab.
In addition, scanners used in MultiFab still have problems scanning certain types of surfaces, such as mirror finishes.
The team plans to continue their research with the aim of creating complex functional objects containing motors and actuators.
Scientists hope their printers will make advanced electronic products and even robots in the future.
MultiFab can be used in electronic, medical imaging, micro-
They believe in sensing and telecom. As for 3D-
Printing enthusiasts, designers, small businesses, scientists say that in the future, they will be able to print their models somewhere as easily as they go to a print shop to copy on a Xerox machine.
\"Imagine a man who sells electric wine --
Openers, but not $7,000 for a printer like this.
In the future, they can go into FedEx and design and print out a batch of finished products at a reasonable price.
For me, such practical use will be the ultimate dream, \"Ramos said in the media --release.
