3dp_atlas2_TITANRobotics_LogoIn 2016, 3D printer manufacturer Titan Robotics started work to build the first commercial multi-head machine featuring Autodesk’s Project Escher technology. Last week at CES 2017, the Colorado-based company was able to unveil the fruits of their labor: the impressive new multi-gantry Cronus 3D printer, featuring not one, not two, but five total print heads that come together to work on a single part at the same time.

3DPrint.com was lucky enough to get a look at the groundbreaking new 3D printer in action on the show floor in Las Vegas, where it was officially introduced.

Titan Robotics founder and CEO Clay Guillory said, “At Titan Robotics, we know what it takes to make a truly industrial large-format 3D printer. This collaborative control technology is going to change everything we know about 3D printing and CNC manufacturing.”

The design software system “intelligently distributes tool paths between multiple print heads working in unison on a single printer.” It offers a wide variety of tools for build preparation, design optimization, and machine configuration, among others.

The FFF-style Cronus 3D printer, combined with the software’s collaborative multi-head printing technology, provides a cutting-edge solution for users in the additive manufacturing world. According to the website, it was designed and built with “premium quality electronics and precision components on all axes.” Its five print heads are capable of 3D printing industrial scale parts with greater detail and speed than traditional single-head 3D printing technology can.

Autodesk Principal Research scientist Andreas Bastian said, “It’s really exciting to upend what has traditionally been regarded as a desktop prototyping technology and show that it’s a powerful way to make large parts – such as molds and fixtures – out of high performance materials.”

multi-head-3d-printing-with-cronusTitan Robotics knows that when you’re 3D printing on a large scale, the printer’s durability, precision, and rigidity are of the utmost importance to get a successful print. When developing the Cronus, the company utilized its innovative technology and proven concepts to decrease any issues with accuracy or detail when it came to 3D printing large, complex parts on the multi-head machine. The foundation of the Cronus is “a welded steel, precision machined frame fitted with the highest quality components, such as 16mm ballscrews, profiled linear rails and Yaskawa servo motors.” The printer’s multifaceted design means that it can be fitted with several different types of tool heads for both additive and subtractive manufacturing. One of these is the pellet extruder, which allows large parts to be fabricated extremely fast at 5 lbs/hour per print head.

In contrast, the large-format Hyperion 3D printer only has a 24″ x 24″ x 24″ build volume. The Cronus comes with a fully heated enclosure, so users can safely print with higher temperature plastics like ABS. However, open air printing is possible for PLA and PETG materials.

“Machines running collaborative multi-head 3D printing technology require a higher level of precision than is typical of large format deposition systems,” said Bastian. “This is why we’re excited to use the Cronus as an ongoing development platform.”

The Cronus will go on the market for commercial sale next month. Discuss in the Cronus forum at 3DPB.com.
