Technical specifications
| Maximum build dimensions | The size of the mold is limited by the dimensions of the vacuum chamber (1,900 x 900 x 750 mm) and by the volume of the product (maximum volume: 10 liters) |
| Standard accuracy | ±0.3% (with a lower limit on ±0.3 mm on dimensions smaller than 100 mm) |
| Minimum wall thickness | At least 0.75 mm to ensure the mold is filled properly; for best results, wall thickness of at least 1.5 mm is recommended |
| Surface structure | High-quality surface finish comparable to injection molding |
