Using 3D Printed Moulds in Producing Cast Replacement Parts and Propellers
At the 74th World Foundry Congress, Speed 3D Mold presented how 3D-printed sand moulds can support the production of replacement castings and propellers without relying on conventional pattern tooling. The presentation brought together selected work involving replacement components, propellers, spherical feeders and helical sprues.

Presentation Overview
Operators of pumps, marine equipment and older industrial machinery regularly reach a point where a cast component is damaged or worn but the original part is no longer produced, the pattern no longer exists, or the manufacturing data is incomplete. The presentation used this industrial context as its starting point.
The work presented described producing moulds and cores directly by 3D sand printing from digital geometry, removing the pattern-making step from the route to a cast replacement part. Selected examples covered replacement components and propellers, together with feeder and gating geometries that become practical when the mould is printed rather than moulded around a pattern.

Topics Presented
Replacement Castings
The presentation covered the production of cast replacement components where the original part is no longer supplied, drawings are incomplete or lead times through conventional pattern making are unacceptable. Moulds were produced directly by 3D sand printing.
Replacement Casting EngineeringPropeller Production
Propeller and impeller work was presented as an application area for 3D-printed sand moulds, including nickel aluminium bronze and aluminium bronze castings recovered without an existing pattern.
Aluminium Bronze Propellers PublicationSpherical Feeders
Trials with spherical feeder geometries were presented as an example of feeder shapes that are practical to produce with 3D sand printing, discussed in relation to casting yield and mould height.
Spherical-Shaped Feeders PublicationHelical Sprues
Helical sprue trials were presented as a gating approach enabled by printed moulds, examined in aluminium-alloy and bronze casting work alongside casting simulation.
