The foundry industry is facing an increasing shortage of skilled patternmakers, creating pressure on production timelines, costs, and capacity. This presentation explores how large format resin 3D printing is emerging as a practical and scalable alternative to traditional patternmaking.

Over the past few years, the cost of industrial resin 3D printing systems has reduced significantly. Equipment that was previously in the range of $500,000 is now available closer to $50,000, while offering improved reliability, accuracy, and surface quality. This shift is making the technology far more accessible to foundries of all sizes.

Modern systems are now capable of producing very large components, with build volumes reaching up to 1700×850×650 mm, allowing full patterns to be manufactured in a single build. In addition, DLP-based systems are available for smaller components, including configurations with automatic part removal to support higher throughput production.

The presentation will cover how these technologies integrate into foundry workflows, including pattern production, material performance, dimensional accuracy, and practical considerations for implementation. It will also highlight how locally developed resin materials can be tailored for specific casting applications.

Monocure3D, as an Australian manufacturer of photopolymer resins, has been working closely with an overseas printer manufacturer to develop systems and materials suited to local industry requirements. This includes customised resins, technical support, and implementation guidance to ensure successful adoption.

The session will provide a clear and practical overview of how resin 3D printing can support the foundry sector as it adapts to ongoing workforce and production challenges.
