The 3 full-scale sculptures are already captured as a clean, watertight STL generated from LIDAR scanning; now I need that positive turned into a complete set of sand-printing molds ready for an ExOne S-Max. The final artwork will be cast in iron, so wall thickness, shrinkage allowance and gating must reflect cast-iron foundry practice. I will provide detailed guidelines covering printer bed dimensions, core requirements, draft angles and the foundry’s preferred gating layout. Your task is to translate the single STL into a mould set that: • fits the S-Max build envelope by sensibly slicing the geometry into printable blocks, • incorporates cores and lock-ins per my guidelines, • includes clear digital markings for re-assembly at the foundry, • is delivered as print-ready STL (and, if possible, source files in the CAD package you work in). We can work iteratively—I will review each section against the guidelines and the foundry will approve before we move on. Experience with large-format sand printing, cast-iron shrink allowances and file-repair tools such as Magics, Netfabb or similar is essential. If you are comfortable collaborating directly with the foundry’s engineering team to fine-tune gating and feeding, even better; I’ll make the introductions once the base split is approved. When finished I expect: 1. A zipped folder of all mould and core STLs, named and organised by print job. 2. Assembly drawings or screenshots that show section orientation and key dimensions. 3. A brief change log so the foundry can trace decisions. I’m ready to share the sculpture STL and the guideline pack as soon as we start, and I’m available for quick feedback so we can keep momentum. Let’s turn this mesh into a flawless set of moulds and get it poured.
