12 of the best 3D pens and 3D printing pens

From mini Eiffel Towers drawn in 3D, to architectural models, to intricate and unique fashion pieces, 3D printing pens have been an integral part of the 3D printing industry, especially on its creative side. Of course, the process of using 3D pens varies quite a lot from standard 3D printing processes in that they do not require any 3D or digital modeling beforehand, a feature that has made them somewhat more accessible than other additive manufacturing technologies.
