Claim 9:
10. The method of claim 9, wherein the step of printing layers of the three-dimensional object from the part material in coordination with the printing of the layers of the support structure further comprises:
feeding the part material to a discharge head member having a throughbore ending with a discharge tip, and a circumferential heater to melt the material in the throughbore;
b′) compressing the part material with a piston and/or the unmelted filament in said throughbore, while simultaneously melting the part material in the discharge head member, so as to extrude a ribbon of part material from the discharge tip;
c) ensuring relative movement in x and y directions of the discharge tip and the receiving platform bearing the sacrificial support structure, while discharging support material on said receiving platform and said sacrificial support structure to form the cross sectional shape of the three-dimensional object, and
d) ensuring relative movement in the z direction of the discharge tip and the receiving platform while discharging part material on said receiving platform and said sacrificial support structure, to form the three-dimensional object in elevation.
