Abstract
Abstract A method of fabricating a part from a computer aided design model using a flowable material and suitable for bridging. The method comprises the steps of constructing at least a portion of a part by successively augmenting a base member (24) by applying new material (22) to the base member; and applying the new material (22) to the base member (24) according to a predetermined design such that construction forces are substantially resisted by axial tension in the newly applied material (22)

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
A method for fabricating a part from a computer aided design model using a flowable material and suitable for bridging, the method comprising the steps of: a) constructing at least a portion of a part by successively augmenting a base member (24) by applying new material (22) to the base member; and b) applying the new material to the base member according to a predetermined design such that construction forces are substantially resisted by axial tension in the newly applied material.
Claim 2
Dependent Claim
23 words
The method according to Claim 1, wherein step (a) comprises applying new material to the base member by tracing a generated extrusion path.
Claim 3
Dependent Claim
33 words
The method according to Claim 1 or 2, comprising the step of generating said extrusion path so that the path comprises segments which are entirely supported from below or are shelves or bridges.
Claim 4
Independent Claim
20 words
The method according to any one of Claims 1 to 3, wherein the base member comprises a molten thermal plastic.
Claim 5
Independent Claim
19 words
The method according to any one of the preceding Claims wherein the new material comprises a molten thermal plastic.
Claim 6
Independent Claim
18 words
The method according to any one of the preceding Claims, wherein an acting construction force consists of gravity.
