MIT’s OpenFab Could Revolutionize 3D Printing Design Process

MIT Researches Use CGI Techniques to Simplify 3D Printing

A group of researchers at MIT are taking a page from the movie business to revolutionize 3D printing. They have developed an architecture pipeline, called OpenFab, that aims to dramatically reduce the learning curve and barriers involved in designing for 3D printing.

“Our goal is to make 3D printing much easier and less computationally complex,” said Associate Professor Wojciech Matusik, co-author of the papers and a leader of the Computer Graphics Group at CSAIL, in an interview with MITnews. “Ours is the first work that unifies design, development and implementation into one seamless process, making it possible to easily translate an object from a set of specifications into a fully operational 3D print.”

With the state of 3D printing today, it’s relatively easy to press print when you have a finished 3D model, but it’s quite a challenge to create a design from scratch that can be 3D printed. OpenFab hopes to change that.

Here is the abstract from the paper published by MIT researchers. Full details available at the OpenFab website.

3D printing hardware is rapidly scaling up to output continuous mixtures of multiple materials at increasing resolution over ever larger print volumes. This poses an enormous computational challenge: large high-resolution prints comprise trillions of voxels and petabytes of data and simply modeling and describing the input with spatially varying material mixtures at this scale is challenging. Existing 3D printing software is insufficient; in particular, most software is designed to support only a few million primitives, with discrete material choices per object.

We present OpenFab, a programmable pipeline for synthesis of multi-material 3D printed objects that is inspired by RenderMan and modern GPU pipelines. The pipeline supports procedural evaluation of geometric detail and material composition, using shader-like fablets, allowing models to be specified easily and efficiently. We describe a streaming architecture for OpenFab; only a small fraction of the final volume is stored in memory and output is fed to the printer with little startup delay. We demonstrate it on a variety of multi-material objects.

3D Printing Architecture From the Cloud with 3D Model-To-Print Service

3D Model to Print

Cloud-based architecture 3D printing service 3D Model-To-Print announced availability of its service in North America after 3 years of development.

3D Model-To-Print (3DMTP USA and 3DMTP LTD) today announces the industry’s first affordable cloud-based service available in North America (www.3DMTPusa.com). Released after three years of development and rigorous testing, 3DMTP’s revolutionary, cloud-based patented technology prepares models to be 3D printed by automatically converting commonly-used architectural software files into 3D printable models, all without the need for costly and time-consuming manual preparation.

3D printing is used in architecture for a more effective and efficient design cycle, and improved visualization between the architect and their audience. The challenge of 3D printing for architects and designers has been the complexity, time, and cost required to prepare 3D design files for printing. With 3DMTP, architects and designers can see a return on investment in about one hour, compared to the traditional manual process.

“The solution that 3DMTP provides is one that has long been needed for our architectural customers,” states Kevin Carr, General Manager of Imaging Division of Mastergraphics — a a 3DMTP USA user, 3D print network member, and both an Autodesk and 3D Systems reseller with locations in Wisconsin, Chicago and Minneapolis. ”Not only does it save hours–even days–in the process of preparing 3D architectural design for 3D printing, it also significantly reduces the cost to prepare the designs, making  3D printing a more usable and affordable option for those wanting to make models of their architectural designs.”

How It’s Done
3DMTP is dedicated to making 3D scaled models printable and available to every architect, developer, and designer at a reasonable price. The innovation is based on cutting-edge algorithms which study the geometric structure of the model, then identify and automatically fix problems that would have prevented it from successfully printing.

“We are committed to providing a state of the art experience that will simplify and enable seamless execution of 3D architectural scale model creation,” comments Ilan Sidi, CTO of 3DMTP and the pioneer of the technology.  

How to Get Started
First, log in to the 3DMTP Portal. Once you are ready to turn your design into a 3D printable model, upload your design file and set your parameters: scale, profile, and desired 3D printer. 3DMTP automatically processes the file without any additional operator interface. 3DMTP also fixes holes between polygons and facets, repairs reverse surfaces, changes the thickness of walls to minimum print tolerance for the selected printer, fixes non-volumetric geometry (making objects “watertight”), and fixes many other problems of degenerated geometry that otherwise would prevent the model from printing successfully.

Become a Member of the 3D Print Network
3DMTP USA is now cultivating a 3D print network in the US and Canada, comprised of 3D printer dealers, BIM/CAD dealers, and 3D print providers such as architectural model shops and reprographics service bureaus.

“We are creating this professional network to help support the anticipated demand for printing 3D architectural models, due to the reduced time and cost to ready AEC models. This increased demand will be a direct result of the introduction of the 3D Model-to-Print™ automated technology into the North American markets,” explains Phil Magenheim, Director of 3DMTP USA.

Autodesk Shows off 123D Catch Software and 3D Printing at Google I/O

Autodesk 123D at Google IO

At the Google I/O conference in San Francisco this week, 3D printing was a popular theme. We reported earlier about the 3D Systems Cubify team hosting a printing station. Also at the conference was the Autodesk 123D team.

They were showing off their design software called 123D Catch, software for your laptop or iPad that lets you import a series of photos of a physical object and create a precise 3D model from those photos. The software is powered by the cloud and takes about 10 to 15 minutes to produce a model. In the example they were showing, the team had taken 30 photos of a marble statue in a museum and the software created a rich 3D model that was ready to print.

The Autodesk team was also printing objects on the MakerBot replicator.
