MJF (Multi Jet Fusion) is an industrial-grade additive manufacturing technology that uses a multi-nozzle array to jet fusing and detailing agents, followed by full-field infrared laser sintering of nylon powder, rapidly producing solid parts with high density and excellent mechanical performance.
Combining batch production capabilities with complex structure formability, it enables integrated topology-optimized designs without supports, widely used in high-end manufacturing scenarios such as automotive structural components, industrial equipment functional parts, and aerospace lightweight components.
Below are our standard MJF tolerances for prototype orders, including one-off/first-time prints, non-production orders, and auto-quoted orders that have not received a manual engineering review. All data is based on HP 5200-Series, Balanced Mode.
| Material Type | Under 30 mm (1.2") | 30–50 mm (1.2"–2.0") | 50–80 mm (2.0"–3.2") | > 80 mm (3.2") |
|---|---|---|---|---|
| Rigid Materials (Nylon, PP) | ±0.70 mm (0.028") | ±0.85 mm (0.033") | ±1.40 mm (0.055") | ±1.75 % |
