1. A system comprising:
a dispensing gun assembly configured to be fluidly coupled with monomer containers by temperature-controlled hoses; and
a computer controller configured to control a dispensing time period during which monomers are dispensed from the containers, through the hoses to the dispensing gun assembly, and out of the dispensing gun assembly as a polymer foam, the controller configured to stop dispensing of the polymer foam out of the dispensing gun assembly upon expiration of the dispensing time period,
the computer controller configured to access associations between different designated polymer foam densities and different values of the dispensing time period, the computer controller configured to change the dispensing time period based on a selection of at least one of the different designated polymer foam densities.
