HighTemp sheet for CORE One L with HT hotend
The double-sided HighTemp sheet is made of spring steel with a powder coating that holds high-temperature materials such as PEEK, PEKK and PPSU on the CORE One L printer with the HT hotend. The coating withstands repeated heating above 100 °C, and its texture is transferred to the underside of the print.
The sheet measures 305 x 310 mm and fits the CORE One L and CORE One L+ with the HT hotend. It is not suitable for PLA and PETG, so for these choose the satin or textured sheet. For nylon and polypropylene, there are the PA Nylon and PP materials sheets.

Fun fact
PPS is not afraid of solvents
PPS, one of the materials for printing with the HT hotend, has a heat deflection temperature of up to 250 °C and a UL94 V-0 flammability rating. The manufacturer also states that below 200 °C no solvent dissolves it.
Frequently asked questions
Can I print PLA on it?
No. The HighTemp sheet is not suitable for low-temperature materials such as PLA and PETG.
How do I clean the HighTemp sheet?
With water and dish soap before every print. Isopropyl alcohol and acetone damage the coating.
Does the print need to cool down?
Yes. The manufacturer recommends leaving the print to cool in the printer to avoid thermal stress.
