Methods of forming objects by depositing flowable material
First Claim
Patent Images
1. A method of forming an object, which comprises the steps of:
- depositing a hardenable flowable material onto an exposed area of a forming surface;
causing said deposited material to at least partially harden on said forming surface to form a portion of said object;
effecting relative sliding movement of said forming surface and said at least partially hardened portion laterally of said area so as to re-expose said area of said forming surface;
depositing further hardenable flowable material onto the re-exposed area of said forming surface to form a further portion of said object laterally contiguous with and in one piece with the at least partially hardened portion; and
repeating the above steps with said object has been formed.

Abstract
A method of forming an object includes depositing a flowable material onto an area of forming surface and allowing the deposited material to at least partially harden on the forming surface to form a portion of the object, and then displacing the forming surface relative to the portion so as to expose at least a part of the area. Further material is then deposited onto the exposed area and above steps are repeated until the object has been formed.

10. A method of forming an object by spraying a sprayable material onto a forming surface which comprises the steps of:
-
directing a spray of said sprayable material onto said forming surface to form a first deposit of said sprayable material on an area of said forming surface; causing said first deposit to at least partially harden on said forming surface so as to form a first portion of said object until the object is formed; causing relative movement of said forming surface and said deposit so as to at least partially expose said area of said forming surface; spraying a further amount of said sprayable material onto said area to form a second deposit of said sprayable material continuous with said first deposit; causing said second deposit to harden on said forming surface so as to form a second portion of said object in one piece with said first position; and repeating the above steps to form further portions of said object. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
