Abstract: An apparatus for making three-dimensional physical objects of predetermined shape by sequentially depositing multiple layers of solidifying material on a base member in a desired pattern, the apparatus comprising: a movable dispensing head (112) having a flow passage (124) therein in flow communication at one end thereof with a dispensing outlet configured in the form of a tip with a discharge orifice (126) of predetermined size therein to dispense material in a fluid state; a supply of flexible strand of thermoplastic resin material that solidifies by cooling to a solidification temperature; heated relatively rapidly to a temperature just above its solidification temperature and will solidify due to a drop in temperature upon being dispensed onto said base member.
