Budget, Complexity, and Strength
FFF is ideal for cost-effective functional prototypes and mechanical parts but lacks high-detail, smooth finishes, and watertight properties.
SLS excels at high-detail prototypes with smooth, watertight surfaces but falls short in mechanical strength, large parts, and flexible materials.
SLA enables strong functional parts with intricate geometries and no supports but is not suited for budget-conscious prints or achieving a smooth surface finish.
Sustainability
FFF is the most sustainable option with low energy consumption and biodegradable materials but is not ideal for high-precision industrial-scale production.
SLS is suitable for small, high-precision prints but has sustainability drawbacks due to toxic resins and high energy consumption.
SLA is advantageous for industrial applications requiring strong parts but has a significant environmental impact due to high energy use, material waste, and CO₂ footprint..
Environmental Calculator for AM parts
Use the calculator to assess sustainability by measuring CO2 emissions (kg CO2/kg) and energy consumption (MJ/kg). It helps optimize energy use, and helps quickly identify eco-friendly printing technologies.
