3D Printing Pen - Model 3DPENU

Now you can 3D print on-the-go with the Velleman 3DPENU 3D Printing Pen! The 3DPENU allows you to touch up prints from your Vertex K8400 or create unique 3D doodles, right from your fingertips.

Using the same 3D printing technology as your full-size printer, the 3DPENU extrudes heated 1.75mm (1/16”) PLA or ABS filament.Hold the 3DPENU like a regular ink pen and let the extruder do the work for you. Once printed, filament cools down and hardens into dynamic 3D structures and shapes.

The 3DPENU has buttons for filament feed speed, filament loading and unloading and temperature controls right on the unit.The unit ships with PEN, power adapter and 1.75mm ABS filament samples


How to Choose the Right Filament

The 3DPENU printing pen accepts both PLA and ABS 1.75mm filaments.

ABS (petroleum based) is the most common filament. It is known for its high melting point (437-482° F), its ability to be both impact resistant and flexible, glossy sheen, and slight odor. ABS filament is best for 3D doodling from stencils, creating bendable items, making spirals and drawing upwards off the page. PLA (plant based) filament is newer and becoming increasingly popular due to its bio-degradable properties. It is less impact resistant than ABS (it’s hard but brittle), lower heat settings (374-464° F), smells sweeter and comes in varying translucencies.

PLA filament is great for 3D doodling on glass, metal and many other surfaces due to its greater adhesion properties.

Both filaments work great with the 3DPENU. Experiment on your own with different projects and find out which works best for you.
