Production of an Innovative, Surface Area-Enhanced and Biodegradable Biofilm-Generating Device by 3D Printing.

The enhanced surface cylindrical flask (ESCF) consists of an eight-striped inner arrangement holding 16 standard microscopic slides placed inside a cylindrical vessel. The specially designed spatula-accessible slides can be withdrawn from the vessel during cultivation without disturbing biofilm formation through an innovative window-flap accessibility mechanism. The vessel and its accessories were three-dimensional (3D) printed by applying a fused deposition modeling technique utilizing biodegradable polylactic acid.
