Title: IMPROVED FDM PRODUCT, METHOD AND APPARATUS
Abstract:
The invention generally relates to improvements in Fused Deposition Modelling (FDM), such that the properties of the model can correspond more closely to the original object on which it was modelled or, in case of a prototype, to the end product. By varying the cross section of a road of deposited material in shape and/or area, the resolution of the product can be increased, without significantly increasing the total time needed to manufacture the product. The invention further relates to a dispensing head having a flat smear surface, and means for cleaning the smear surface. Further improvements to the FDM technique are also disclosed.
