Good Dimensional Stability
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.
Reasons to choose Ultimaker CPE
Product designers use CPE to make extremely tough and dimensionally stable functional prototypes.
- Excellent chemical resistance
- Excellent toughness and dimensional stability
- Good interlayer adhesion, especially when using the front door add-on
- Low levels of ultrafine particles (UFPs) and volatile organic compounds (VOCs)
- Ideal for short run manufacturing and functional prototype
Printing Specifications
Temperatures
Ultimaker CPE requires a build plate temperature of 70 C. Use the table below to find the temperatures per nozzle diameter for the best print results:
| Nozzle diameter (mm) | Nozzle temperature (C) | Build plate temperature (C) | Print cooling fan speed (%) |
| 0.25 | 245 | 70 | 20 |
| 0.4 | 250 | 70 | 80 |
| 0.6 | 260 | 70 | 80 |
| 0.8 | 260 | 70 | 80 |
The temperatures listed in the table are used for the Ultimaker CPE print profiles in Cura for the Ultimaker 2+ and Ultimaker 2 Extended+. For best results, it is crucial to select the right printer, nozzle diameter and material in Cura. Also make sure to select the correct material on your Ultimaker 3D printer to automatically use the corresponding temperatures.
Cooling
For optimal quality, the print cooling fan speed for Ultimaker CPE is set to 80 %. For the 0.25 mm nozzle, a regular print cooling fan speed of 20 % is sufficient as the amount of extruded material and the nozzle temperature are lower. For shorter layers, the print cooling fan speed is gradually increased to 100 %, to ensure optimal quality throughout the print.
Cura Adhesion Settings
In preconfigured Ultimaker CPE Cura profiles, the default build plate adhesion method is a brim. A brim is made of a few extra printed lines around the 3D print on the initial layer to improve adhesion and avoid warping.
Adhesion
Although Ultimaker CPE adheres well to the glass plate, it does tend to warp heavily. To minimize warping when printing with Ultimaker CPE, apply a thin layer of glue to the glass plate using the glue provided in the accessory box of your 3D printer. In addition to the adhesive properties, the glue serves as a protective layer for the glass plate.
The Ultimaker CPE emits a low level of gasses and particles when 3D printed in accordance with the temperatures in the table above. To ensure a comfortable and healthy environment, we recommend 3D printing in a well-ventilated area.
