How Accurately Can You 3D Print My Model?

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 things. 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.

Material Accuracy
ABS, high-detail resin ± 0.1% (with a lower limit of ± 0.2 mm)
Titanium
± 0.2% (with a lower limit of ± 200µ)
Gray resin, mammoth resin, transparent resin
± 0.2% (with a lower limit of ± 0.2 mm)
Polyamide (MJF) ± 0.3% (with a lower limit of ± 0.2 mm)
Alumide, polyamide (SLS)
± 0.3% (with a lower limit of ± 0.3 mm)
Rubber-like
±0.9%(XY) up to ±1.8% (Z) with lower limits on ±1 mm (XY) up to ±1.5mm (Z)*
Steel
± 1% (after 2-3% shrinkage compensation)
Aluminum ± 2% (with a lower limit of ± 200µ)
Brass, bronze, copper, gold, silver Minimum accuracy ± 5% (including finish and geometry variables)
Average accuracy ± 2% (around ± 0.1 mm)
High-detail stainless steel, multicolor+ N/A
