Our 3D wax printers leverages high‑precision material‑jetting systems engineered to handle low‑viscosity, thermoplastic wax formulations with tightly controlled melt–flow characteristics. Layer thickness between 8–16 µm, enabling sub‑100 µm feature resolution and sharply defined edges. The wax chemistries are optimised for predictable coefficient‑of‑thermal‑expansion behaviour, minimal residual ash after burnout (<0.01%), and rapid solidification, which collectively reduce pattern deformation during handling and casting. Our Advanced systems incorporate closed‑loop feedback for droplet placement, and multi‑material deposition to create soluble support structures. These capabilities allow the generation of highly complex internal geometries, thin‑wall sections, and topology‑optimised patterns that integrate seamlessly into precision investment‑casting workflows.
