Nozzle Diameter

The diameter of the nozzle provided in the pen.

The larger the nozzle, the thicker the lines produced by the pen will be (ceteris paribus; the actual thickness of the lines will also depend on the type of plastic and the adjusted temperature). In the thinnest models, the nozzle diameter is less than 0.5 mm, in the thickest models it is about 0.9 mm. Most modern 3D pens have nozzles in the range of 0.6 – 0.7 mm — this value is considered the most versatile and convenient for practical use.

Number of Speeds

The number of fixed speed settings provided in the pen. This spec is specified only if there is more than one such setting.

The speed control allows you to adjust the mode of operation to the circumstances: for example, a low speed will be convenient for fine work, and a high speed is so for large elements. And the more speed settings there are in the pen, the wider the choice for the user to configure the device more accurately. In the most advanced models, the number of speeds can reach eight.

Note that the speed adjust can be not only stepwise, but also smooth (see above).

USB powered

The pen is powered by a standard USB connector. Such devices are as versatile as possible in connectivity: they can be powered via a PC, a portable device like a laptop or tablet, an external power bank, a USB wall charger or car charger.
