Buying guide


There is an online community of 3D printing enthusiasts and if you find that you love printing and making your own designs, you should definitely join them. But before that, make sure to get a good 3D printing pen. There are several factors that you need to take into account when looking for one, so here are some things that we consider important when choosing a 3D printing pen.



Types of pens

There are mainly two kinds of 3D printing pens, and they both depend on the solidification of the material used at just the right time. The first category is the thermoplastic ones. They work by threading a plastic filament through the pen and extruding it at the pen’s tip. The plastic needs to quickly melt and then solidify immediately.

The “ink” used in these pens is thermoplastic and it comes in an array of colors, usually with the diameter of 0.07 inches. These pens usually produce a distinct smell that is not always pleasant. That is why users should work with them in well-ventilated areas. You might even want to protect your face with a respiratory mask because the vapors can be toxic.

As an alternative, you can try the other kind of 3D printing pens available – the UV ink ones. Unlike the thermoplastics, the ink of this pen starts as a liquid and when the UV light from the tip of the pen comes in contact with it, it solidifies. This brings the advantage of causing no heat and thus no danger of burns.


Can children use it?

After discussing the types of 3D pens that you can find, it’s important to see if they can safely be used by everybody. As mentioned, thermoplastic pens produce vapors and an unpleasant smell often associated with toxic substances. They can also be hazardous because they require heat and that can lead to accidents in the hands of inexperienced people.

Children, in particular, should be watched when they’re using this kind of pens. Toxic substances can be found in paints or glues too, so, like it’s the case when using those, you should keep the area that you work in ventilated.

The better alternative is represented by UV ink pens. They require no heat and produce no toxic gases, making them a lot safer for children. Furthermore, keeping in mind that a similar procedure is used in dental practices and in curing gel manicures, it might seem that using these pens might not pose a danger to one’s health.

However, staring too much into the light can be harmful to the eyes so if your kid is using the pen you need to make sure he or she doesn’t do it for too long.




Once you know what type of printing pen you want and how safe you want it to be, you should look at the features it provides. The possibility to change the speed of the extruded material is something that offers more control and a pleasant experience. Depending on your experience level and what you want to achieve you might want to draw faster or slower.

Usually, cheap 3D printing pens use thermoplastics to do their work and in their case, you would want to find a pen that’s capable of using different melting temperatures so it can accommodate different plastics such as PLA or ABS.

Design and comfort are two things that are also important. Printing pens that feel closer to the original writing pen seem easier to use and offer a better feeling.


Taking into account all the aspects presented, we have decided on some of the best 3D printing pen models and showcased them below so you can pick a model that offers plenty of features at the right price.


Polaroid Draw


At first glance, this chunky printing pen doesn’t offer all that much, with a plastic body and the possibility to choose between 4 plastic colors – black, transparent, red and green. However, it offers some great capabilities, such as the possibility to power it via USB. This can prove to be a great feature for child safety reasons, as you don’t want your kids to get around power sockets.

It’s also more accessible to use near your computer or laptop. So in terms of power flexibility, it does great. This 3D printing pen is easy and intuitive to use. After you plug it in, you need to wait for a red light to turn blue and you’re ready to go. To keep the pen upwards while not in use and to mask the hot tip, the manufacturers included a stand useful for idle periods.

The filament cools and hardens very fast so you will need to practice a bit before you can achieve the wanted designs. To make things easier, the pen is capable of adjusting the speed at which the material comes out.

Including a special plastic tracing sheet, this 3D pen also has its own app that can be downloaded on smartphones. This helps with grasping the drawing process better and helping in creating the more intricate designs.

Kuman 3D Printing


Having a round body, this 3D printing pen is very similar to a classic pen, just a bit thicker. It might seem quite bulky due to the wide bottom, but it fits comfortably in hand. To help you during your drawing it has an LCD display that shows the temperature, speed and how much filament you have left.

It’s a product easy to use by beginners because the material takes little time to harden up, and that makes for a faster and more controlled process. If the device detects that it has been idling for 5 minutes, it engages the automatic standby mode. A filament jamming detection system also lets you know what’s happening to the material in real time.

Designed to work silently, this pen will not buzz your ear, and can also be used late at night or when you don’t want to disturb people around you. Having the capacity to print between temperatures of 320 to 446 Fahrenheit degrees, it allows you to use different thermoplastics – ABS and PLA are the alternatives.

The package comes with a spatula that can be used for art painting and an Ebook that you might need to learn more about 3D printing. Furthermore, the customer service is very responsive and it will be there to help when needed.

PowerTRC Doodler


Offering some decent quality 3D prints, this pen stands out because it has a small LCD display that allows you to select the temperature and the speed at which you can print. If the pen stops working, the display will show an error letting you know what happened.

A reverse function can be activated to pull the material back when the pen jams, but some users say that this doesn’t always work. Because you can control the temperature at which the plastic is melted, you have the possibility to use both ABS and PLA plastics. The pen comes with some ABS spools packaged with it from the start.

Like most manufacturers, the makers of this printing pen advise that you only use their special thermoplastic when drawing. The standard size of filament that the pen uses is 0.07, but the nozzle size can be adjusted to accept other widths of filaments.

This model is one of the safest in its category because it has a holder that can be used to rest the pen when not working with it. This hides the pen’s tip so there is no danger of burns. Thus, kids over the age of 8 can safely use it. When drawing with it you will notice it is pretty quiet.
