There are some general suggested guidelines based on the experiences of the authors which can be used in addition to ensure safety and reliability of biomimetic parts in real world applications : 1 For lattices , thin struts might contain micro-porosity , rough surfaces and manufacturing imperfections which affect the mechanical properties sometimes more strongly than thicker features .
 material: be; concept or principle: safety; process characterization: reliability; concept or principle: biomimetic; concept or principle: lattices; machine or equipment: struts; concept or principle: surfaces; concept or principle: manufacturing imperfections; concept or principle: mechanical properties
