A method may include fused filament fabricating a fused filament fabricated component by delivering a softened filament to selected locations at or adjacent to a build surface. The softened filament may include a sacrificial binder and a powder including a shape memory alloy (SMA). The method also may include removing substantially all the sacrificial binder from the fused filament fabricated component to leave an unsintered component; and sintering the unsintered component to join particles of the SMA and form an SMA component.

A method of fabricating a burner element for an abatement apparatus is disclosed. The method comprises: injection moulding a charge comprising metal particles and a flow compound into a mould defining the burner element to produce a moulded burner element; and sintering the moulded burner element. In this way, injection moulding is used to produce the burner element, which provides far more flexibility regarding the design and properties of the burner element and avoids the necessity of incorporating a perforated support into the burner element. This allows burner elements of more intricate design to be produced, as well as burner elements which are thinner than those produced using existing techniques, which increases the volume of a combustion chamber defined by that burner element for any external burner element size, which in turn increases the amount of effluent gas that can be treated for any burner size.

Systems, apparatus and methods of additively manufacturing objects are disclosed. Specifically, provided herein are methods of heating objects having a particle-based support at least partially surrounding the object during portions of stages of the heating. Additionally, systems, apparatus, and methods for removing the particle-based support during heating, such that the object can continue heating to form a final part. Systems, apparatus, and methods for distributing the particle-based support to shore the objects through heating are disclosed. Systems, apparatus, and methods for removing the particle-based support are also disclosed herein.

Assemblies fabricated by additive manufacturing include an object and a base plate providing support to the object during the manufacturing process. The geometry of the base plate is defined to optimize space and material constraints. During sintering, the base plate is reduced in area in a manner complementing the reduction in the footprint of the object, preserving the fidelity of the finished object.

A method may include fused filament fabricating a fused filament fabricated component by delivering a softened filament to selected locations at or adjacent to a build surface. The softened filament may include a binder and a primary material. The binder is configured to release a secondary material upon heating at or above a conversion temperature. The method also may include heating the fused filament fabricated component to a temperature at or above the conversion temperature to sinter the primary material to form a sintered part and cause the binder to release the secondary material within the sintered part.

A steel, a steel mechanical part, an electronic device, and a preparation method for a steel mechanical part are provided. The steel includes components of the following mass percentages: chromium: 7% to 11%, nickel: 2% to 7.5%, cobalt: 6% to 15%, molybdenum: 4% to 7%, oxygen: a trace to 0.4%, carbon: a trace to 0.35%, and iron: 50% to 80%. The steel provided in this application has relatively high mechanical strength and is not easily deformed, and therefore a risk of fracture caused when an electronic device using the steel falls off from a height is reduced.

Support substrates are used in certain additive fabrication processes to permit processing of an object. For additive fabrication processes with materials that are sintered into a final part, a multi-layer support substrate of interleaved support and interface layers is fabricated to support an object while reducing an impact of friction on shrinkage of the part during the sintering process.
