CPE is a copolyester. Makers sell it for industrial and laboratory parts, a maker certifies its colours for food contact, and another stresses its gloss and clarity. Its HDT at 0.45 MPa is 70–80 °C. On the H2C it prints on a 110 °C bed without chamber heat, but a maker calls it moisture sensitive and Prusa Research's knowledge base says drying and storage matter.
Partly documented Tensile modulus (XY), tensile strength (XY), notched Charpy impact, HDT at 0.45 MPa and price rest on 2 products each and tensile strength (Z) is not published. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials
Against PLA, CPE is 93 % more expensive and 35 % less stiff, and its HDT at 0.45 MPa is 19 °C higher. Against PETG, CPE is 2.5 times as expensive and 12 % stronger flat, and its HDT at 0.45 MPa is 5 °C higher. Among the materials, CPE has a low tensile modulus (XY), notched Charpy impact and HDT at 0.45 MPa: each is in the lowest quarter of the materials that publish it. The rest of its key properties sit in the middle half.
CPE costs more than PLA, PETG and ASA and others but is less stiff than CPE-CF, PLA and ASA
How does it compare with what an engineer would buy instead?
- CPE: its products' median and middle half
- an alternative
- lowest to highest
- each material's median (top row)
Each row is a material, each column a property: the bar is the middle half of a material's products, the tick their median, the hairline their lowest to highest; the ticks above the rows are every material's median.

Printing on the H2C
CPE prints within the H2C's limits and softens near 75 °C, above its 65 °C chamber
What does printing it on the H2C take, and how hot can a part get?

One temperature axis for the settings a print needs and the temperatures a part meets. A setting's shade is how many of the products whose sheets give a window accept each degree; the H2C's limit closes its row.

No CPE product gives a heated chamber window. Windows read from the Bambu Lab Filament Guide are not shaded: the guide speaks for every product that reads it.

Where a product's own sheet is silent, its setting comes from a sheet it shares or from the Bambu Lab Filament Guide; each product's card says which.
What makers say about printing it
Printing advice
For the best part strength, it is recommended to print with the least amount of fan cooling.

Moisture sensitivity
Moisture sensitive! Keep in protective bag.
Fillamentum CPE HG100, data sheet, p. 1
On CPE in general
- Lower warping than ABS. Smooth PEI can need a release layer. Bed / warping after Prusa Research, CPE | Prusa Knowledge Base
- Hygroscopic; drying and storage remain important. Moisture after Prusa Research, CPE | Prusa Knowledge Base
