Is it for me?
Fillamentum CPE (co-polyester) is a high-technical material for the FFF (also known as FDM) 3D printing technology. Engineered for quality and easy printing with features that will dwarf all PET based materials.
CPE (co-polyester) is a tough material with high impact resistance and tensile strength. It’s especially suitable for printing mechanical parts and functional prototypes. Similarly to PETG, it doesn’t warp or produce unpleasant smell during printing. It’s chemical resistant and the layer adhesion is excellent.
CPE is also 100% recyclable material, BPA free and environmentally friendly. When printing thin layers, it also offers great transparency. And one more thing - parts can withstand temperatures up to 80 °C.
Important notice for the mk3 users
Before you start printing CPE, turn off the filament sensor. You can do it in LCD Menu - Settings - Fil. sensor [on/off].
|High impact resistance||No vapor smoothing with acetone|
|High tensile strength||More abrasive than standard PETG|
|Great chemical resistance|
|Great layer adhesion|
This CPE is made in the Czech Republic by Fillamentum.
Approximity length of filament: 254 m
1.75 mm filament is manufactured with precision of +- 0.05 mm
We reserve the right to ship weights +/- 5% due to packaging variations.
Before printing, make sure the surface of heatbed is clean as described in 3D Printing Handbook.
Smooth PEI surface preparation! Make sure to apply Kores glue on the smooth PEI before printing. Glue serves as a separating agent and helps to protect the surface when removing the finished print from getting damage. Without the glue, the filament adhesion may be too strong!

CPE HG100 black is my favourite for functional mechanical cockpit fixtures in light airplanes e.g. radio bracket and antenna mounts. Prints perfectly on clean (!) textured plate without stringing or warping. Nice glossy finish and the textured surface looks great. I use heat inserted brass threaded inserts for part assembly and they just cannot be pulled out. Absolutely brilliant filament. Withstands 80C/176F so the sun up here in the north is no problem but in (sub-)tropical you might need to shield for direct sunlight or use lighter colours? Test it.
Obviously, the Prusament PETG sticks nicely to the textured bed but there was no way I could get this CPE HG100 (in Vertigo Grey) to stick to it. I guess that I will have to use glue and the smooth bed!
Sticks to the bed so use glue as suggested in the description. Works great for mechanical parts like gears and stuff. Not to good for small parts or parts that need support material.
