Some of our prototypes are of smaller dimensions and have finer details printed on them. In this case, we use a SLA 3D printer. If necessary, we print the item in a 0,025mm resolution, which means that every vertical millimetre of 3D print is composed of 40 layers. At this resolution, the individual layers cannot be seen with bare eye.
An example of this kind of 3D print is this connector in the pictures below.
