The Glyby Intelligent 3D pen is a standard plastic filament-melting 3D pen that is surprisingly reliable.

The Glyby pen comes with the pen itself, available in four colors, along with the power adapter, instruction manual, and 3 different colored lengths of ABS filament. Several users have reported that the instruction manual is not the best, however understanding how tot use the pen itself is straightforward.

WGlyby Pen 2hat it Can Do

The Glyby pen is a fairly standard pen, with the usual ergonomic form factor and rear-loading plastic filament.  It has a speed control slider on one side and two feed/retract buttons on the other. Two LEDs indicate power and when the pen is working. There is also an overheat alarm that sounds when the pen gets too hot; it can go off sometimes, but as long as the “working” LED pen stays green there isn’t a problem.

The pen can use either PLA or ABS plastic, and uses standard 1.75mm filament, making replenishing the pen easy and affordable. The biggest issue the Glyby pen has is the temperature adjustment, a flathead screw terminal (almost certainly the head of a simple potentiometer) hidden under a rubber cover allows the user to adjust the temperature, but no indication is given as to which direction to turn the potentiometer or by how much, or even what the current temperature is. Once the right temperature is dialed in however, it shouldn’t be adjusted unless you plan to switch between PLA and ABS.

What it CANNOT Do

This 3D pen, like many others, is compared heavily to 3D printers, and marketed as a cheap alternative. While the concept and plastic materials are the same, a 3D pen is to a 3D printer as a pen is to a traditional printer. The pen has more versatile and creative uses, but without extraordinary skill it will not match the precision of a machine.


Final Thoughts

The Glyby 3D pen is another run-of-the-mill 3D pen that has everything you should expect from a 3D pen. The only feature that really puts it ahead of other pens is that it doesn’t seem to have a problem with running to fast and jamming or just flat out breaking. Expect some trial and error dialing in the temperature and be very patient if learning to use a 3D pen for the first time.
