Eastman Creates Odor-Free, Styrene-Free, 3D Bio-Polymer
Staff posted on September 07, 2014 |

Eastman Chemical Company, a specialty chemical company, and Helian Polymers, a leader in the masterbatch and biopolymer industry, have teamed to launch colorFabb XT-Copolyester made with Eastman Amphora 3D polymer. The new low-odor, styrene-free polymer is uniquely suited for the 3D market with benefits in air quality, dimensional stability and regulatory compliance:

Air quality

 Low odor


 Generate fewer ultra-fine particulates than ABS

Dimensional stability

 Tough thermoplastic material creates stronger, more detailed parts

 Temperature resistance to create functional parts

 Great layer bonding for reliable processing and great part finish

 Chemical resistance for long-lasting good looks and performance

FDA compliance

 Complies with certain U.S. Food and Drug Administration (FDA) regulations for
 food contact applications


ColorFabb XT-Copolyester will be on display at the 3D Printshow in London from Sept. 4 to 6. Printed samples, including a 3D puzzle chair, will demonstrate the filament’s capabilities at the show. Individual pieces of the puzzle chair, printed prior to the show, will be joined together to create a functional chair used in the booth.

The collaboration between Eastman and Helian, brand owner of colorFabb, began in 2013 with the goal of developing a solution for functional 3D products printed using extrusion-based 3D printing. The companies worked to test materials and formulations, utilizing their expertise in high-performance polymers and 3D printing filaments. Eastman’s history with a broad portfolio of solutions and technical expertise complemented Helian’s innovative work with 3D printers and filaments. The resulting colorFabb XT-Copolyester made with Eastman Amphora 3D polymer focuses on functionality and features strength, workability, processing, aesthetics and low odor for 3D printed products.

“Although fast-growing, extrusion-based desktop printing has yet to see a solution for functional parts. Our collaboration with Helian has allowed us to go beyond prototypes,” said Alex Dudal, market development representative, Eastman Chemical Company. “With Eastman Amphora 3D polymers, parts can be printed with a dimensional stability and functionality for industries such as manufacturing, healthcare, technology, education and retail.”

Eastman Amphora 3D polymers will provide makers of 3D filaments with a consistent, high-quality product. It will empower consumers to create strong, functional 3D products through desktop printing, while ensuring good air quality and dimensional stability with a material that complies with FDA regulations. Looking to the future, Eastman is considering tailoring options — like color and texture — for additional solutions.

“The number of advancements we’ve been able to make in a relatively short amount of time is a testimony to the potential of our relationship with Eastman,” said Ruud Rouleaux, managing director, Helian Polymers. “Taking advantage of new, better-performing materials is the advancement the 3D printing industry needs to venture out of laboratories and into small businesses, schools and homes.”
