What is 3D Printing Pen and How to Use It?

3D Printing Pen

Over the decades, the 3D printing pen sector has experienced tremendous growth and advancement. Pens that can be 3D printed are one such invention. Kids, artists, amateurs, and expert designers have all benefited from its joy and utility.

The device’s ability to generate a 3D solid object out of thin air gives it an almost mystical quality. But one still questions whether a 3D pen is a real instrument or a fun. The truth is that it might be one, or both, or neither!

Confused? Be at ease! The definition of a 3D printing pen, its operation, and a list of varieties and applications will all be used to clarify what is meant in this article.

What is a 3D Printing Pen?

Similar to a bigger version of a regular pen, a 3D printing pen utilizes plastic filaments as opposed to lead or ink. It resembles a portable 3D printer because it creates actual objects out of nothing.

When using a 3D pen, you construct a model from scratch without the aid of a computer or other software; rather, your hand acts as the controller. The majority of 3D printer pens are driven by a battery or a wire connected to an USB connection or a wall outlet.

The greatest 3D pens allow you to showcase your imagination in three dimensions by “drawing” with hot plastic filament. You can make sophisticated 3D models and art with even the most affordable 3D pens, as well as toys. The 3D pens may also be utilized to embellish already completed creations.

Using a 3D pen is akin to using a glue gun. When you click on a button, a form of liquefied plastic, like ABS or PLA, is pushed out and swiftly cools in the air before solidifying. Drawing models from nothing is one method to use them to create art. Another option is to adorn an already-existing model or other item. As an option, you may make 3D forms by connecting a number of flat shapes.

Working of a 3D Printing Pen

Based on its type; hot pen or cold pen, a 3D printing pen operates in two ways. The plastic filament in hot pens is comparable to that of 3D printers. After being put into the pens, the filament is warmed up until it melts and is then extruded.

3D Printing Pen Working

The air surrounding the pen quickly cools the hot filament as it exits. On any surface or in the air, one may draw intended things using this technique. Hot 3D pens function similarly to hot glue guns if you’re aware of those.

The chemical transformation of a liquid into a solid is made possible by a cold pen. The ink’s status as a photosensitive substance makes this feasible. Employing UV light, it solidifies as soon as it exits the pen’s tip.

Who Can Use a 3D Printing Pen?

3D printing pens can be identified by its intended user in addition to how it functions, such as a youngster, an enthusiast, or an expert.


A 3D pen which doesn’t generate a great deal of heat is the type that is suggested for youngsters because it is secure to use. Kids should consequently prefer cold pens; although, hot pens also are acceptable if used under parental guidance. They also make “warm” pens. These pens resemble hot pens but employ a unique material that melts at a reduced temperature.


An excellent 3D pen for hobbyists is one that is both highly useful and reasonably priced. Support for diverse materials, little temperature variance, and speed adjustments are examples of typical characteristics. Switches for both emptying and extruding may also be present on such pens.


The most advanced 3D pens are those used by experts. They normally provide a wide range of parameters that are extremely customizable along with excellent accuracy. Check these pens for two instances:

Applications of 3D Printing Pen

Are 3D Printers Harmful to the Environment?

Is 3D Printer Harmful

We advise choosing PLA, or Poly Lactic Acid, as the material for your 3D pen if you want to prevent environmental damage. This form of plastic is ecological and biodegradable since it is made from renewable sources, often fermented plant starch like maize, cassava, sugarcane, or pulp from sugar beets. To be more precise, it usually requires six to twelve months to decompose, compared to several hundred years for most plastics.

ABS, the alternative form of plastic frequently utilized in 3D pens, isn’t the best choice for the environment. ABS, which stands for Acrylonitrile Butadiene Styrene, is made up of petroleum and is not biodegradable. It is more harmful to people than PLA and is also detrimental for the ecosystem.


Now that you’ve seen a few of the fundamental ideas underlying 3D printing pens, we hope you can understand how a 3D pen can serve as both a toy and a tool. It ultimately comes down to the pen being utilized and the person utilizing it.

Whenever it comes to classrooms, creative endeavors, or product design, a 3D pen may be a valuable tool. However, when used for arts and crafts, sketching, and general amusement, it is a toy.
