PET CF is easier to print than most composites. It is more resistant to moisture and when kept in an UltiMaker Material Station, it should remain dry. Unlike other composite materials, PET CF is also available in multiple colours: black, blue, and gray. PET CF is compatible with UltiMaker support materials (PVA and Breakaway) giving full geometric freedom when designing parts. Finally, parts printed with PET CF can be annealed to improve their temperature resistance from 80 °C to a phenomenal 181 °C, as well as
increasing their strength by 30% and stiffness by 10%. All of this can be done using the recommended and validated BINDER FP115 programmable oven.

Print Orientation
As the FFF process produces part in a layered structure, mechan- ical properties of the part vary depending on orientation of the part. In-plane there are differences between walls (following the contours of the part) and infill (layer of 45° lines). These differences can be seen in the the data for XY (printed flat on the build plate - mostly infill) and YZ (printed on its side - mostly walls). Additionally, the upright samples (Z direction) give information on the strength of the interlayer adhesion of the material. Typically the interlayer strength (Z) has the lowest strength in FFF. Note: All samples are printed with 100% infill
Tensile Properties
Printed parts can yield before they break, where the material is deforming (necking) before it breaks completely. When this is the case, both the yield and break points will be reported. Typical mate- rials that yield before breaking are materials with high toughness like Tough PLA, Nylon and CPE+. If the material simply breaks without yielding, only the break point will be reported. This is the case for brittle materials like PLA and PC Transparant, as well as elastomers (like TPU).
