# The extruder's components
nozzle = instance `Nozzle
liquefier = instance `Liquefier
# The material (filament) used
material = instance `Materials2
# The parts that provide force to the filament
actuated_gears = instance `ActuatedGears
# The properties of the part produced that depend on the material
service_temperature provided by material ≽ provided service_temperature
# The resolution depends on the nozzle (as well as material?)
part_resolution provided by nozzle ≽ provided part_resolution
# Each material has a liquefaction temperature
temperature provided by liquefier ≽ liquefaction_temperature required by material
force provided by actuated_gears ≽ force required by nozzle
# The time it takes to produce the part depends on the part volume
# and the nozzle properties (time_per_unit_volume)
required time ≽ (time_per_unit_volume required by nozzle) · provided part_volume
# The cost of materials depends on the part volume and the specific cost
# of the material
material_mass = provided part_volume · density required by material
cost_of_filament = (specific_cost required by material) · material_mass
required budget_per_part ≽ cost_of_filament
# The total budget is the sum of budgets
required budget ≽ ∑ budget required by *
