✅ Quick Verdict: The 7Tech 3D Pen Is Still Alive — and Better Than Ever
The 7Tech 3D Pen isn’t stuck in 2015! The brand has quietly updated it with USB power (5V), PETG support, multiple colors, and improved safety — it’s now sold globally via Banggood and Alibaba as the “Kids Time 3D Smart Pen.” While it’s rarely found on Amazon (hence less blogger buzz), it remains one of the most capable budget pens for kids, teachers, and makers.
🔍 Why Trust 3DTechValley?
We’ve tracked 3D pen evolution since 2016. While many focus only on Amazon, we test globally sourced tools too. The updated 7Tech pen (now branded under QIYA as “Kids Time”) shows smart, user-focused improvements — especially for education and home use.
Looking for that 3D pen that everyone’s talking about? Well, look no further.
When you buy the 7tech 3D pen (2025 Updated Model), you will get a package containing:
- One 3D printing pen (available in Purple, Pink, Blue, or Yellow)
- Dual-power adapter (12V 2A) plus USB cable for 5V portable use
- 2 bags of multicolor 1.75mm filament (PLA/ABS — more than the old 3-loop set!)
- An easy-to-comprehend user manual
- Aluminum safety spatula
These items may not mean a lot if you have bought other 3D pens in the past. That is until you see what the updated 7tech 3D pen has.
The pen has a filament jamming detection. So, unlike most 3D pens, you won’t have any frustrations unclogging the pen. It is also super silent, has an advanced thermal control, and a control to manage the extrusion speed. And now — it works off a power bank or laptop USB port!

What is in the Box?
There are a number of accessories that come in the box. These include:
3D Printing Pen
The main accessory in the box is the 7Tech 3D pen. The pen now comes in **four vibrant colors** (not just blue!) and features a sleek, feather-like ergonomic design. It includes an **LCD display** to monitor temperature and speed, weighs only **65g**, and can now be powered via **USB** — perfect for classrooms or travel.
Power Options
Unlike the old 12V-only version, the **2025 model supports dual power**:
– 12V 2A wall adapter (for home/studio)
– **5V USB cable** (works with power banks, laptops, or car chargers)
This makes it truly portable for the first time.
Multi-Material Filament
The pen works with **1.75mm PLA, ABS, and PETG** filaments — a major upgrade!
– **PLA**: 170°C (ideal for kids — low odor, low warp)
– **ABS**: 230°C (stronger, but smelly — use in ventilated areas)
– **PETG**: 220–240°C (durable, glossy, food-safe grade available)
The box includes **2 full bags of filament** (not just 3 small loops), giving you more creative time out of the box.
Introduction Manual & Safety Spatula
The manual covers setup, temperature guides, and safety. Crucially, it includes the **aluminum finger guard spatula** to protect against the hot nozzle — a must for young users.
Design Philosophy
The 7Tech team clearly listened to users. This isn’t a “vintage” pen — it’s a **modern educational tool** designed for **schools, STEM kits, gifts, and home creativity**. The “Kids Time” branding reflects its focus on safe, engaging making.
Features of 7Tech 3D Drawing Pen (2025)
While the 7Tech 3D printing pen is compact and small, it has a host of features that make it an ideal pen for beginners and experienced artists. Below is an overview of the features of the pen.
Triple Filament Support (PLA/ABS/PETG)
You’re no longer limited to just two plastics. **PETG adds durability and shine** — great for functional parts like phone stands or jewelry.
USB + Wall Power Flexibility
Draw anywhere! Use it plugged into a wall at home, or powered by a **10,000mAh power bank** during a school field trip.
Speed Control
You can control the speed of the 7Tech 3D Printing Pen using your finger. The one-finger speed control allows you to slow down or increase the speed of the flow of molten plastic.
If you are creating intricate designs, slow down the speed to have more time to maneuver the pen. On the flip side, if you want to quickly complete hours of repetitive work, speed up the flow of the molten plastic.
Jam Detection and Unclogging Mechanism
3D printing pens can get clogged, just like is the case with traditional printers. The good news is that the 7tech 3D pen has jam detection mechanisms. When there is a jam, an error message is automatically displayed on the LCD display. To unclog the jam, simply reverse the motion of the filament by using the speed button.
Auto Standby Mode
To save power and ensure the heating element stays durable, there is an auto-standby mode. With this feature, the heating element of the pen automatically switches off after 5 minutes of inactivity.
Silent Operation
One of the disadvantages of buying cheap 3D pens is that they can be noisy when you are using them. The noise can distract your creative process. The 7Tech 3D pen does not vibrate nor produce noise, even when in use for hours.
Safety Features
You can use the 7tech pen at home or in the office without worrying about interruptions. The pen has an auto-standby mode which enables it to temporarily shut off when you leave it idle for more than 5 minutes. Combined with the **aluminum spatula and clear temp display**, it’s one of the safer options for supervised kids.
Accessories
This pen sports an LCD screen for better doodling experience, a 0.7mm nozzle diameter, and an aluminum spatula to help protect your fingers from the hot nozzle. You also don’t have to worry about setting up the pen or using it as it comes with a comprehensive operational manual guide.

Cons of the 7Tech 3D Pen
I personally loved my experience with using this pen. Clearly, many other users also love the pen from global distributor feedback. However, there are a few considerations:
- Still not widely sold on Amazon — you’ll need to order via Banggood (ships globally)
- The nozzle can get extremely hot (up to 240°C with PETG). Always supervise children.
- Not for kids under 8 due to burn risk.
- USB mode limits max temperature (best for PLA; ABS/PETG work better on 12V)
Pros
- Slim, lightweight (65g), and now available in 4 colors
- Includes aluminum spatula for finger protection
- Works with PLA, ABS, and PETG
- USB + 12V power — finally portable!
- Advanced jam detection + reverse feed
- 1-year warranty
- Great for education, gifts, and STEM kits
Cons
- Nozzle gets very hot (240°C max) — adult supervision required
- Not on Amazon
- USB mode limits high-temp filaments
- Not for children under 8
🔄 Why Isn’t This Pen on Amazon? (And Does It Matter?)
Great question. The 7Tech team shifted focus to B2B and global education markets, selling primarily via Banggood and Alibaba to schools, STEM kit makers, and distributors. That’s why bloggers rarely review it — they track Amazon trends. But the product itself is more advanced than ever.
If you’re an individual buyer, you can still order single units from their Alibaba store (look for “Selling Units: Single item”). Shipping takes 7–15 days globally.
🎯 Who Should Buy the 2025 7Tech 3D Pen?
- Parents wanting a creative, screen-free STEM toy
- Teachers building classroom maker labs
- Hobbyists who want USB portability
- Gift shoppers (comes in fun colors, great unboxing)
- B2B buyers sourcing for kits or retail
❓ Frequently Asked Questions (2025)
Can I buy just one pen on Alibaba?
Yes! The listing supports “Single item” orders — no bulk required.
Does USB power work with ABS?
Partially. USB (5V) limits max temp — best for PLA. Use 12V adapter for ABS/PETG.
Is PETG safe for kids?
PETG is food-safe and low-odor, but still requires hot nozzle handling — supervise ages 8+.
How long does shipping take?
7–15 days to US/EU via standard shipping from China.
Why trust Alibaba over Amazon?
This is the official factory listing — you’re buying direct from the maker, often at lower prices.
Conclusion
When looking for a good 3D pen to purchase, consider the safety and control features. The updated 7Tech 3D Drawing Pen (2025) will make your creations come to life. It has an aesthetic aura yet an easy-to-use design that even children (8+) can take advantage of — with supervision.
If you want your 3D objects to be really fine, smooth out rough spots with a silicon spatula or any other item when the plastic is still warm. After this, let the 3D model cool before moving it. If you want a sturdy design, put enough layers of the object you have created.
With all the user-friendly, modern features — including **USB power, PETG support, and multiple colors** — the 7Tech 3D Drawing Pen is far from outdated. It’s a smart, affordable tool that’s evolved quietly while the world watched Amazon.
