System, method, and computer program product for introducing foam into a confined space

An object fabrication system comprising:

• a digital file storing metadata describing an object having an interior;
• and
• a hardware processor configured to access foam specification data describing at least one type of foam including each foam's expansion factor, and which, accordingly, and according to said file describing the object, controls introduction of said at least one type of foam into the interior,
• wherein dividing the object's volume by the expansion factor yields an amount of foam mass to be used for an injection.

A computer program product, comprising a non-transitory tangible computer readable medium having computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a fabrication method comprising:

• providing a digital file storing metadata describing an object having an interior;
• and
• configuring a hardware processor to access foam specification data describing at least one type of foam and which, accordingly, and according to said file describing the object, controls introduction of said at least one type of foam into the interior,
• wherein foam characteristics which are stored include each foam's expansion time (time required for foam to expand to its final volume) and/or time required for each type of foam to harden and wherein the hardware processor receives inputs determining which types of foam are to be inserted, and then accesses, from memory, characteristics of each type of foam and, accordingly, determines a roadmap for inserting these foams including which should be inserted first, how much of each type to insert, and how long to wait between inserting one type of foam and inserting a next.
