Dimensional accuracy strongly depends on the selected material and technology. It doesn’t relate to the detail of your model but to the deviation from the nominal size.
Please take note that accuracy and level of detail are not the same. The level of detail can be described as the difference in height between two surfaces (e.g. extruded text on a surface).
Accuracy values are listed below and clearly indicated on each material page.
| Technology | Material | Accuracy |
| Fused Deposition Modeling | ABS, ABS-ESD7, PC-ABS, Polycarbonate, Ultem 9085 | ± 0.15% (with lower limit on ± 0.2 mm) |
| Laser Sintering | PA 12, PA-AF, PA-GF, Bluesint PA12 | ± 0.3% (with lower limit on ± 0.3 mm) |
| Polypropylene (PP) |
XY: 0.35% (lower limit of 0.35mm) Z: 1.2% (lower limit of 0.5mm) |
|
| Metal 3D Printing | Aluminum (AlSi10Mg), Titanium (TiAl6V4), Stainless Steel (316L), Inconel (IN718) |
Better than or equal to the industry standards: DCTG 6 of DIN EN ISO 8062-3 for dimensions between 0.5 and 30 mm DCTG 8 of DIN EN ISO 8062-3 for dimensions between 30 and 400 mm DIN ISO 2768-1 c (coarse) for dimensions between 0.5 mm and 400 mm See design guidelines for more information on standard accuracy.

* Please note that our CAD team will position the parts so that the lowest dimension is positioned in the Z-axis for the best possible result. By selecting the ‘keep orientation’ option, you acknowledge that the general rule described above will not be followed as the the orientation will not be modified by our CAD team.
