The present application relates to a method and system for removing material from an additively manufactured part. The method comprises providing an additively manufactured part comprising a part section and a support structure, providing a material having an expansible volume, carrying out an application step, wherein the material is applied to the additively manufactured part and carrying out a de-coupling step, wherein the material is expanded from a first, unexpanded, state to a second, expanded, state so as to generate a separating force for de-coupling the part section and the support structure.

Additive fabrication methods for 3D composite objects having preform fiber reinforcements embedded in a matrix material include providing local heat and mechanical energy to at least partially melt, impregnate and solidify the matrix material forming at least one reinforced composite layer of the object. Successive layers are added in accordance to a computer generated tool path to form a three dimensional object with useful features.

A protective mask for a part, the part including a plurality of openings in a surface thereof, is provided. The protective mask includes a mounting member at least partially within each of at least two of the plurality of openings. Each mounting member includes a water soluble material. A masking member couples the at least two mounting members. The masking member includes a non-water soluble material. Each mounting member includes a first plurality of integral layers of the water soluble material, and the masking member includes a second plurality of integral layers of the non-water soluble material. The protective mask can be made by a two material additive manufacturing system. A related method is also provided.

A method for manufacturing a three-dimensional shaped object includes a structure shaping step (step S140) of shaping a structure with a shaping material including a metal powder or a ceramic powder, a support shaping step (step S130) of shaping a support T that supports a structure S with a support material including a resin, and a deresining step (step S210) of deresining the support T supporting the structure S.

A three-dimensional device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

A manufacturing method of a three-dimensional formed object includes disposing a first forming material on a forming table to form a plurality of structures which are separated from each other, and disposing a second forming material for forming the three-dimensional formed object such that the three-dimensional formed object is supported by the plurality of structures in a state of being separated from the forming table.
