Ultimaker CPE+ material is chemical resistant with high dimensional stability, with the added advantages of increased temperature resistance and higher impact strength compared to regular CPE.
CPE+ is a straight upgrade to CPE, but requires a little bit more tuning and specific settings to print well. It provides good layer adhesion and a higher glass temp so if you need to print parts that are chemical resistant, or watertight, this is your best bet! In general, CPE+ is a well rounded material with good print characteristics, strength, and mechanical properties.
CPE+ is a little bit more challenging to print than PLA, but not as difficult as Nylon. It doesn't warp as much and doesn't have moisture issues. Compared to regular CPE, the glass temp is much higher so there is much higher tolerance for temperature deformations.
We recommend CPE+ for people who are looking at a general engineering material. CPE if you want color options.
CPE (co-polyester) materials are chemical resistant, tough and demonstrate good dimensional stability. It is a preferred choice for both functional prototypes and mechanical parts. While both CPE and CPE+ provide similar performance characteristics, CPE+ provides the added benefit of higher temperature resistance and increased impact strength.
Ultimaker's CPE+ can be compared to Colorfabb HT in properties and characteristics.
CPE spools come in 0.75kg. 2.85mm diameter and approximately 90m long.
