The eamolds need to be cleaned in isopropyl alcohol after the printjob.
Drying is necessary to enable the solvents to evaporate from the cleaning process.
Post-curing process is carried under inert atmosphere (nitrogen). This step is necessary to ensure the biocompatibility and the mechanical characteristics.
We recommend to lacquer 3D printed earmolds with egger LP/H lacquer. Optionally: polish the surface mechanically or drum-polishing.
