Sand 3D printing accuracy explained: the ±0.3-0.5 mm mold band, where accuracy comes from, mold vs casting tolerance, and how it is verified – without the brochure numbers.

Entry-level sand 3D printing for small foundries: the J1800 entry point, utilization math, service bureau vs own machine, staffing and financing for 5-30 person shops.

3D printed sand molds are single-use, but the sand comes back at ~95%+ through reclamation. How the loop works, what stays reusable, and the cost and sustainability impact.
