The Best 3D Pen

Since 2013, I’ve been discovering, studying, and testing 3D printers—and sometimes 3D pens—for tech publications including Gigaom, TechCrunch, and now Wirecutter. I understand the shortcomings of the technology as it exists, and also its potential.

When researching this guide, I interviewed Rachel Goldsmith, a New York–based artist who uses 3D pens prominently in her work (and who the 3D-pen brand 3Doodler commissioned to do artwork in the past) about the general features that matter the most when using a 3D pen. I also spoke to Joseph Flynt, who writes frequently about 3D pens for industry blog 3D Insider, about notable pens he has tested.

A 3D pen is the handheld cousin of a 3D printer. You feed strands of hard plastic (called filament) into the pen, and the pen melts the filament and extrudes it out of the tip as a string of gooey plastic. By holding the pen like a regular pen and drawing in any direction—including straight up into the air, with practice—you can create 3D art, figurines, game pieces, or basic plastic objects like baskets and phone holders. You may even be able to repair broken objects made from ABS plastic by using a 3D pen to “weld” the pieces back together with melted ABS.

3D pens can be useful to people of all ages and ability levels—even kids as young as 8 can use models specially designed to be safer to work with, like our also-great pick. They tend to appeal to anyone who already likes 3D printers, drawing, or modeling, though they offer less fine-grained control during the creative process than many artists may be used to: Drawing a clean-looking model with a 3D pen takes a lot of practice, which means that beginners should be okay with their creations looking a little more organic.

This freeform drawing aspect is also what makes 3D pens especially appealing to kids, though for those who prefer more guidance or structure, a wealth of stencils are available online for creating anything from the Golden Gate Bridge to a rhinoceros beetle. Manufacturers generally do not recommend 3D pens for children under 8, but we think use by a responsible younger child under adult supervision is fine.

If you already own a 3D printer, you might feel like you already have enough plastic objects in your life. But working with a 3D pen is more creative and satisfying because you’re actually producing something with your hands instead of designing with software and letting a printer produce it. You can also combine 3D printing with 3D drawing by using a 3D pen to fill in mistakes in a printed model, or to finish it with colorful details. And 3D pens don’t have a size limit like a 3D printer—you can work at virtually limitless scale.

While searching for 3D pens to test, we consulted existing buying guides from sites like 3D Insider, Popular Science, and Code Mom. We also asked our experts about the most important features to look for and potential flaws to avoid.

You can spend up to $300 on a 3D pen, but not everyone needs the extra features found on high-end models, such as more-powerful motors (which allow for more precision and additional extrusion options) or the capability to print using unusual materials. You can also find pens for less than $25, but they get poor reviews, and we didn’t come across any worth testing. The best pens for most people tend to cost between $25 and $100 and have the following features:

• Comfortable to hold: Because 3D drawing projects usually take significant time, comfort is important. Although one of our experts said it’s possible to get used to the shape of any 3D pen, we preferred a pen with a more ergonomic shape that’s comfortable from the start. And the heat from the part of the pen that melts plastic shouldn’t make the grip area uncomfortable to hold.
• Reliable: The pen shouldn’t be prone to filament clogs or break easily.
• Steady plastic extrusion: The pen should put out a steady, even strand of plastic at a comfortable speed, adding to your sense of control over the pen.
• Customizable settings: Pens that give you a choice of extrusion speeds make it easier to switch between slower detail work and faster infill work, and multiple temperature settings make it possible to work with a wider range of filament types.
• Continuous extrusion: A continuous-extrude option (where you simply press a button once to start drawing) is easier on your hand during longer drawing projects than a button you have to hold down.
• Easy to load: Whether you want to load in a fresh string of plastic or swap the existing one for a different color, it should be simple and fast to load and unload filament.
• Swappable tips: Pens that come with (or have the option to buy) multiple tip sizes allow you to draw in different thicknesses, which is useful for switching between details and filler.
• Portable: The pen should be cordless or at least have a cord that’s long enough to use in a variety of work environments. In our experience, a cord of less than around 6 feet of length still felt a bit too short.
• Good customer service: The company behind the pen should be reachable if something goes wrong. It’s a bonus if the pen has a generous replacement policy or warranty.
• Widely compatible filament: Most 3D pens are compatible with lots of different brands of filament, but some require uniquely designed plastic that has special features—or locks you into buying from the same company. A 3D pen that can work with a range of materials and brands is better.
• Safe: The pen shouldn’t give off dangerous or overly smelly fumes.

Using the above criteria, we narrowed our list to eight 3D pens for an initial round of testing in early 2018: the 3Doodler Start, 3Doodler Create, Scribbler 3D Pen (discontinued), Mynt3d Printing Pen, Soyan 3D Pen (discontinued), Polaroid Draw (discontinued), 3Dsimo Basic, and Tipeye Smart 3D Pen (discontinued). In late 2018, we tested the 3Doodler Create+ and 3Doodler Pro (discontinued). In late 2020, we tested the 3Doodler Pro+.

I tested all 11 pens myself and then enlisted the help of a panel of four kids, ages 8 to 10, to further test the two pens appropriate for people under 12. For the initial test, we evaluated how comfortably each pen fit into testers’ hands and took note of whether it felt too hot after extended use. We drew a straight line across a sheet of plastic, constructed a small box that required drawing straight into the air, and built a 10-inch-tall model of the Eiffel Tower using a paper stencil.

We also evaluated the settings on each pen, including how easy it was to change the temperature and speed. We loaded and unloaded filament and watched out for jams. We also made note of how much smell and noise were produced.

For our kid test panel, we asked each child to use each of the two pens for up to 30 minutes apiece. We provided the kids with books of stencils but let them decide how they wanted to play with the pens. Some kids used the stencils, others chose to free draw. We then asked the kids to pick their favorite pen and explain what they liked and disliked about each.

The 3Doodler Create+ offers the best overall drawing experience for people ages 12 and older who want to start working with 3D pens. In our testing, it drew clean lines of plastic that solidified quickly, was the easiest to use, and was one of the most comfortable to hold. It comes with the widest variety of useful accessories, and should you ever need assistance, 3Doodler’s customer service is by far the most responsive we encountered.

3D drawing projects can take a while to complete, so we like that the triangular coated aluminum body of the Create+ feels natural to hold, even over long periods of use. Your finger rests naturally within reach of two buttons that you press once to start or stop extruding at a slow or fast speed, respectively—a design we found ideal for achieving fine control while drawing. The Create+ also stays comfortably cool while drawing, unlike many of the earliest 3D pens.

The Create+ puts out steady, even strands of plastic as you draw. The lines solidify quickly and stay put when you draw over them; most other pens grab onto still-soft filament and drag it along, warping your drawing. We appreciate that instead of having to hold a button down to extrude the plastic, you just press once, which adds to this pen’s comfort for long periods of drawing. The Create+ has a speed range that’s somewhere in the middle of the pack for pens we tried, but both its fast and slow settings are comfortable for normal drawing. The pen is also the best among those we tested at drawing lines straight into the air—something we didn’t do all that often during normal use, but that’s a much-hyped ability for 3D pens.

Loading filament is easy with the Create+; it follows the standard 3D pen procedure, which is similar to that of a glue gun. To unload filament, you press and hold both extrude buttons until the strand of filament is loose enough to tug out. 3Doodler recommends unloading the pen after every use to prevent long-term damage from storing plastic inside it. The pen lets you choose between two heat settings, for ABS plastic (about 380 degrees Fahrenheit) or PLA plastic (about 360 degrees), which is all you need if you’re using 3Doodler’s line of filament options (more on this below).

Supposedly, one of the most common problems with any 3D pen is a filament clog (caused by melted plastic hardening and getting stuck inside the pen), and 3Doodler pens are the only ones we tested that come with tools designed to fix clogs. However, we never had the opportunity to use it because the Create+ pen—like all 11 pens we tested—never actually clogged for us.

The Create+ is among the only pens we tested with the option to buy additional tip sizes (you can buy them for the 3Doodler Create and Pro pens too). One of our experts strongly recommends extra tips, as thin tips give you more control over detail work, and thick tips are better for filling in large areas more quickly. After testing the various tips, we agree. If you want more control over detail work or to speed up infilling, the additional tips will help. There are also two ribbon-like shapes that can be useful for adding texture. You don’t have to buy these tips for a good experience with the Create+, but they certainly help. One word of caution: Make sure the pen is hot when you swap a tip or you risk permanently breaking your pen.

As a part of our testing, we sent each 3D pen company an email asking if it is safe to use third-party filament. We found that 3Doodler responded within minutes—the fastest of any company we queried—and was one of only a handful of companies that responded at all. After shipping it halfway across the country twice, the original Create pen we tested stopped working and we had the chance to interact with 3Doodler’s customer service again. As before, someone responded within minutes by email. Within 25 minutes of the first response, the person helping us had diagnosed an electrical issue and offered to send a replacement. All 3Doodler pens are covered by a one-year warranty.

We got similar line control from the Tipeye Smart 3D Pen, our former budget pick, despite the Create+ costing significantly more. However, we found that the Create+ model’s other strengths make the additional cost worthwhile. We also noticed that the Create+ has a tendency to pause to reheat when you stop extruding, which can be annoying when you are stopping and starting frequently to draw fine details. It slowed down the overall pace of our drawing, but it was worth the wait to get evenly heated filament in return.

The Create+ comes with 75 10-inch strands of plastic, which is more than you get with most of the pens we tested. However, the ABS and PLA filament refills for the Create+ pen—which come in a wide range of colors and types—are the most expensive of any pen we tested. (The company says that using third-party filament voids the pen’s warranty, as 3Doodler’s pen motors are designed to handle straight, short strands of plastic, not the longer, coiled strands common to inexpensive third-party filament.) For example, a pack of 25 10-inch strands (20 feet of filament) for the Create+ starts at $8, compared with 240 feet of third-party filament for our budget pick for around $15—which works out to about $1.25 for 20 feet. That’s a fivefold difference, but considering that 20 feet is enough filament for roughly two hours of constant drawing at the Create+ pen’s fast speed, it’s not a huge difference on a per-project basis. (The Eiffel Tower in the photo above took about an hour, including starting and stopping.)

The shorter filament strands of 3Doodler pens also run out faster, which means you have to stop and reload a Create+ more often than you do pens from other manufacturers. Reloading while drawing can be annoying—especially if you wait too long to reload and the pen just stops extruding plastic.

As was the case with all of the other pens we tried, using the Create+ with ABS filament gives off a chemical-like odor, while PLA filament strands smell more like maple syrup. Also like other models, the Create+ produces a whiny motor noise while drawing. It’s annoying but not loud enough to bug someone in the next room.

The Create+ has a 5.9-foot cord that’s fairly standard for a 3D pen, but it felt a bit short in our work environment: You want a lot of slack in the cord so you don’t feel any tugging from the top of the pen as you work. We recommend buying an extension cord if you don’t plan to use the pen directly in front of an outlet.

After testing two kid-safe pens with the help of a panel made up of four children, we think the 3Doodler Start is the best option for anyone under age 12. We noticed during testing that kids like to touch and mold the pens’ extruded plastic, which means that pens with hot tips that use ABS or PLA plastic—including the Create+—are not safe for them to use. The 3Doodler Start has a cool-to-the-touch tip and makes use of special plastic that comes out of the pen at a cooler temperature so kids can draw and mold however they choose.

Our four-kid panel was split on which pen they preferred overall, but all four kids liked using the Start, and only two liked the 3Dsimo Basic. The Start is smaller and curved, which a majority of the kids said made it fit better in their hands; the Basic is longer and flat like a candy bar. Neither pen clogged during testing, but because their tips are shorter than an adult-friendly pen, the part of the pen around the tip had a habit of dragging through half-dry plastic and getting gunked up. Both pens got gunky enough to annoy the panelists, though the Start gunked noticeably less than the Basic.

It’s possible to draw steady, straight lines with the Start, but because it uses filament that has a more claylike texture and takes longer to dry than the filament in our other picks, it requires more patience while using. In fact, it’s the slowest pen of any we tested because you have to move slowly and wait for lines to dry completely before attempting to draw over them again.

Some of the testers found drawing with the 3Dsimo Basic to be slightly easier because the pen uses PCL plastic—a material that performs closer to the PLA used in the adult pens. We also found that drawing a line straight into the air was much harder with either of the kid-friendly models, because it takes the just-extruded plastic from these pens so long to dry. Neither model has temperature controls.

We didn’t encounter any problems loading or unloading the Start, but as with our top pick, you’re stuck using 3Doodler’s expensive refill filament. And one tester disliked the short, straight pieces of filament (which need to be reloaded more often than other types) so much that he preferred the 3Dsimo Basic overall.

You cannot buy other sizes of tips for the Start. However, you can charge it and use it without a cord—a feature we wish all 3D pens had. And like the Create+, the Start benefits from the fastest-responding customer service team of any pen we tested. The Start is also backed by a one-year warranty. It produced virtually no odor and was quiet enough not to annoy patrons in a coffee shop during our kid test panel.

We’re gearing up to test a new round of 3D pens, including the Scrib3d P1, the 3Doodler Flow, the 3Doodler Start+, and the Mynt3d Junior 2. We’ll put these pens through their paces and update this guide with our thoughts soon.

The 3Doodler Pro+ is the most comfortable pen to hold and gave us the greatest amount of control over our lines. It’s one of the most flexible pens we’ve tested when it comes to materials, too: While the Create+ is compatible with PLA, ABS, and Flexy plastics, the Pro+ adds additional options like wood (blended with plastic), copper (also blended with plastic), and nylon. It also allows for precise temperature control, which makes it easier to work with unusual third-party materials. However, these benefits weren’t enough for us to recommend the Pro+, because it costs more than three times as much as the Create+. That pricing rules it out for anyone but the most devoted 3D pen users.

The 3Doodler Create is the older model of the Create+ and was our previous top pick. We like it for many of the same reasons as the later model, including comfort, customer service, and tips for drawing multiple line sizes. Its brushed aluminum exterior also looks a bit more polished than the Create+ model’s plastic shell, in our opinion. However, the Create+ handles filament noticeably better, making drawing smooth, straight lines easier. If you want a pen that shares most features with our top pick at a cheaper price, the Create could be a good option while it’s still available.

The Mynt3d Printing Pen the company loaned us was dead on arrival—it would load filament only a few millimeters at a time and heated up only when we held one of its buttons down, which is not the way it’s designed to work. But the squarish shape of the pen would have been enough to disqualify it for comfort reasons: Unlike with the other pens, our fingers did not rest naturally on the extruder button. Mynt3d did not respond to our customer service request.

We tested the cool-to-the-touch 3Dsimo Basic against the 3Doodler Start to find the best 3D pen for kids. 3Dsimo is one of the few companies (along with 3Doodler) that responded to our customer service request, and the pen is compatible with cheaper, third-party filament. Although three of the four kid testers thought the Start’s smaller size made it easier to hold in their smaller hands, one thought the Basic allowed them to draw in greater detail. In our own testing, we agreed: While the Start extrudes claylike plastic that is easier to mold, the 3Dsimo’s plastic feels closer to what’s used in adult pens (despite being cool to the touch immediately after extrusion). The Basic comes with a beautiful book of stencils that’s larger and better printed than the Start’s stencil booklet, but the pen is also more expensive and not as widely available as the Start.

The 3Doodler 3D Build and Play isn’t a traditional 3D pen; you turn a handle to extrude a string of soft plastic into a mold to create shapes. We tried it in person at Toy Fair in 2020 and found it underwhelming. While it’s safe to use for children ages 4 and up, we found it still took some skill to use the molds, and the results looked sloppy.
