What we talk about when we talk about co-polyesters

Two years ago, in the summer of 2014, we announced our partnership with Eastman Chemical Company. Eastman is a worldwide specialist on co-polyesters, a material we recognized to have benefits for 3D printing. In the past two years we have launched three filament grades with Eastman’s raw materials, branded as Eastman Amphora™ 3D polymer.

Why co-polyesters?

The way we see it, FDM 3D printing filaments will be all about functionality in the future. How you are going to use your prints in the real world will define what material you choose. We have found a lot of characteristics in Eastman’s range of Amphora co-polyesters that offer functionality, durability and efficiency. Added benefits compared to ABS are the low-odor while printing and that Amphora based filaments are styrene free.

Compared to PLA, Amphora features a much better heat resistance, starting at 75C for colorFabb XT, 85C for colorFabb nGen and 100C for colorFabb HT. You can find the comparison between our co-polyesters, ABS and PLA in the table below:

 

More information about emissions during 3D printing can be found in the brochure that Eastman has prepared after some extensive studies. You can find the pdf extract of this study by clicking the button below:
