The STL files for 3D printing were downloaded from Thingiverse and Allevi3d or designed with Tinkercad from Autodesk, Inc. A commercial DLP 3D printer (Asiga PICO2) comprising the LED light source of 405 nm with customized resin tray and printing head with heating functions, was used to fabricate all the objects. Post-curing of the 3D-printed products was conducted using a UV chamber from CL-1000 Ultraviolet Crosslinker from UVP (Ultra-Violet Products Ltd.).
