MYNT3D Super 3D Pen Review
I‘ve been messing around with 3D printing for a couple of years, but the big desktop printers always felt like a commitment. Then I stumbled across the MYNT3D Super 3D Pen and wondered if a handheld pen could actually let you draw in the air.
Worth it if you’re a creative tinkerer or a parent looking for a mess-free STEM toy; skip it if you need precision for engineering prototypes. After digging through hundreds of user reviews and comparing specs, here’s the full picture.
1. MYNT3D Super 3D Pen
The MYNT3D Super 3D Pen is a handheld 3D printing pen that melts 1.75mm filament and extrudes it through a heated nozzle, allowing you to draw 3D structures freehand. It supports both PLA and ABS plastics, giving you flexibility for different projects. In our research, it's one of the most recommended pens for beginners and hobbyists.
Setup and first impressions
Out of the box, the pen comes with a 10-foot power cord, a sample 10g spool of PLA filament, and a tiny tool for cleaning the nozzle. Verified buyers across 500+ reviews mention that the pen feels solid and well-built, with a smooth matte finish. The LED display shows the current temperature and speed setting, which is intuitive.
You plug it in, press the temperature button, and wait about 60 seconds for it to reach 190°C. The included silicone nozzle cover is a nice safety touch. Some users note that the nozzle gets hot fast, so it's important to keep the cover on.
The first few strands may be a bit stringy until the filament flow stabilizes. After that, you're ready to draw.
| Filament diameter | 1.75mm |
| Supported materials | PLA, ABS |
| Nozzle diameter | 0.7mm |
| Temperature range | 160–230°C |
| Extrusion speed | Adjustable (low, medium, high) |
| Weight | 65g (2.3 oz) |
| Power input | 100–240V AC, 12V 2A DC adapter |
| Cable length | 10 ft (3 m) |
Daily-use experience
Performance
The stepper motor drives the filament smoothly, and the feed mechanism rarely jams according to user reports. The pen can sustain a continuous extrusion for about 2 hours before the motor housing gets warm. For finer details, the lower speed setting works well, but for thick supports, high speed is better.
One thing I noticed in aggregate reviews: the pen works best with PLA. ABS requires a higher temperature (around 220°C) and a bit more patience to avoid stringing. The temperature can be adjusted in 1°C increments, which is handy for dialing in different brands.
Ergonomics
The pen is shaped like a fat marker, with a soft-touch surface that feels comfortable in the hand. The buttons for temperature and speed are on the top, easy to reach with your thumb. Verified buyers say it's light enough to use for extended sessions without fatigue.
However, the cord is a bit stiff and can get in the way. A few users recommend using a cord clip or a cable management holder to keep it out of your workspace. The pen also lacks a built-in spool holder, so you have to feed filament manually or rig a small stand.
Build quality
The body is made of ABS plastic and feels sturdy. The nozzle is metal and seems durable. The silicone cover stays in place well.
One common complaint: after a few months of use, the LED display can become dim, but it's still readable in normal light.
The included cleaning tool works, but some users suggest buying a separate nozzle cleaning kit for deep maintenance. Overall, the pen feels like it will last if you take care of it.
✓ Pros
- Variable speed control gives flexibility for detail vs fill work
- Works with both PLA and ABS without needing a separate nozzle
- Included 10-foot power cord gives plenty of reach around a desk
- Temperature can be adjusted in 1°C increments for fine-tuning
- Silicone nozzle cover protects fingers from accidental burns
✗ Cons
- No built-in spool holder; you need to feed filament manually or buy a stand
- The LED display is not backlit, so it’s hard to read in dim light
- Some users report inconsistent extrusion after prolonged use without cleaning the nozzle
- The cord is a bit stiff and can tangle if not managed
Who should buy it
Buy it if you…
You’re a hobbyist who wants to create 3D art without a desktop printer. This pen is also great for teachers introducing STEM concepts. The low learning curve and included sample filament make it easy to start.
If you enjoy making keychains, small sculptures, or even repairing plastic parts, this pen is a fun tool.
Skip it if you…
You need high precision for functional parts like gears or brackets. The manual extrusion requires a steady hand, and layer lines are visible. Also, if you’re on a very tight budget, cheaper pens exist but often have worse build quality.
Consider this only if you’re willing to invest a bit more for reliability.
Better alternatives
- 3Doodler Start+, Safer for kids (uses low-temp plastic) and has a built-in spool holder, but it’s pricier and only works with PCL filament.
- Creality 3D Pen, Offers an OLED display and preset temperature profiles, but some users report less consistent extrusion than the MYNT3D.
Frequently Asked Questions
Does it work with PETG filament?
The manufacturer recommends only PLA and ABS. PETG requires higher temperatures (around 230-250°C) and a different nozzle material. Using PETG could damage the PTFE liner inside the nozzle.
Stick to PLA and ABS for best results.
How long does the heating time take?
From cold start, the pen reaches 190°C in about 60 seconds. The LED display shows the current temperature, so you can see when it’s ready. Some users say it takes a bit longer for ABS (around 90 seconds to reach 220°C).
Is the nozzle replaceable?
Yes, the nozzle is a standard 0.7mm brass type that can be unscrewed and replaced. You can find replacement nozzles on Amazon. A few users recommend buying a spare nozzle for future use.
Can I use it with a spool holder?
The pen does not come with a spool holder, but you can easily use a standalone spool holder or a filament guide. Some users 3D-print a simple holder that attaches to the table. The manual feeding works fine for short pieces, but a holder is helpful for longer projects.
What safety precautions should I take?
The nozzle reaches 230°C, so keep the silicone cover on and avoid touching the tip. The pen is intended for ages 14 and up. Always unplug it when not in use.
The National Institute of Standards and Technology (NIST) has resources on additive manufacturing safety that are worth reviewing.
Final verdict
4.3 / 5 stars, The MYNT3D Super 3D Pen is a reliable, well-built entry point into handheld 3D printing. It balances performance and price better than most competitors in its tier. If you’re a creative hobbyist, a teacher, or just want to try 3D drawing without a big investment, this pen is a smart buy.
For professional prototyping or kids under 12, look elsewhere.
