More precisely, biofilms can cause infections in the human body, affect water quality, and damage industrial installations and equipment. Research and industry have been working to find various solutions for preventing and removing this threat. Potential solutions, such as health products, drugs and industrial removal products, are tested on artificially formed biofilms.

Second, biofilm printing adds automation and scalability, making biofilm formation processes more efficient, and thus, cheaper. <b>Hence, Biolink can help to design safer and more effective anti-biofilm solutions, by increasing biofilm testing process efficiency and resemblance to reality. </b>
