Built to Keep Flowing

Every detail is aimed at the two things that ruin most 3D pens: jams and mess.

1°C LCD Precision

Set the exact temperature on the top screen, from 160°C to 230°C. PLA, ABS, or a new filament brand, you dial it in by the degree.

Universal 1.75mm Feed

Takes the same standard filament as desktop 3D printers. No proprietary sticks and no $20 refill packs.

Ventilated Ceramic Tip

Lower cooling slots and a perforated black cone keep heat at the 0.7mm ceramic nozzle, where it belongs.

Contoured Hand Fit

A curved 62-gram matte barrel that sits naturally in a writing grip, whether the hand is 8 years old or 48.

How It Works

Set Your Temperature

Set Your Temperature

Press the 'M' button under the LCD to pick PLA or ABS, then adjust in 1°C steps. The ceramic core reaches 190°C in about 45 seconds.

Press and Draw

Press and Draw

Hold the side feed button and a smooth 0.7mm bead flows from the tip. Let go and it stops instantly, with no stringing.

Reverse to Unload

Reverse to Unload

Press the reverse button and the motor backs the filament out of the rear intake. Swap colors or put it away without a jam.

Why Choose the Cosari ExtruPen Pro?

Cosari ExtruPen Pro Detail

Anti-Clog Auto Retract

The motorized reverse button pulls filament back out cleanly, so softened plastic never cools into a plug inside the barrel.

Zero-Stringing Stop

Release the button and extrusion stops right away. Clean line ends, less cleanup, less wasted filament.

2-Year Warranty

Backed by a 30-day money-back guarantee and a 2-year replacement warranty on motor and heater faults.

A great gift for my 8-year-old

My 8-year-old makes pins and all sorts of things with this. The filament flows smoothly, and the curved matte body fits smaller hands without feeling bulky. It heats quickly, and the top LCD makes switching between PLA and ABS modes straightforward.

Responsive and comfortable

This pen stops feeding the quickest when I release the black side control button. I've had zero filament stringing or cleanup with it. The rectangular LCD on the glossy black top spine is clear, and switching between PLA and ABS is easy.

Fun way to learn

My 11-year-old loves this gift! It's been a great way to learn the basics of 3D extrusion and weld or add details onto existing 3D prints. The light-blue finish looks nice, and the black nozzle tip is perforated.

The one I kept

I tested a couple of 3D pens and ended up keeping this one. The two black side buttons and the M mode button below the top LCD are intuitive and responsive, so I didn't have to keep checking the instructions.

Christmas gifts for my granddaughters

I bought two for my 7-year-old granddaughters for Christmas, one light blue and one purple/pink so they each had their own color. They love them! Learning to draw in 3D does take a lot of patience, though.

Comfortable for longer projects

The curved barrel feels lightweight and balanced in my hand, even when I'm crafting for a while. I also like the design, including the lower ventilation slots near the black conical tip. It's comfortable to hold without gripping too hard.

A hit with my friend's son

I bought this for my best friend's son, and he was so excited to try it. He got into building little 3D models right out of the box using the starter filament coils.

My kids love it

Great product! My kids love watching the LCD heat indicator climb before they start drawing. The lower air vents near the tip seem to help keep the grip area cool, too.

Handy for finishing prints

I use this to weld PLA parts together and fill seams on my 3D printer builds. It heats up quickly, the feed buttons respond well, and the rectangular LCD is easy to read. The curved profile is comfortable for detail work.

Smooth flow and simple operation

The instructions were easy to follow, and the filament feeds smoothly at a useful range of speeds. I unload it cleanly after each session to help prevent clogs in the white ceramic nozzle tip inside the perforated black cone.

Frequently Asked Questions

Does the Cosari ExtruPen Pro need special refills?

No. It takes any standard 1.75mm PLA or ABS filament, the same material sold on cheap spools for desktop 3D printers.

Is it safe for an 8-year-old?

With adult supervision, yes. The perforated black cone shields the hot ceramic tip, and the lower vents keep the curved grip comfortable. The tip itself gets very hot, so kids should learn never to touch it.

How do I stop it from clogging?

Press the reverse button to unload the filament before you unplug the pen. In our testing, that one habit plus the pen's vented barrel meant zero jams across 40 hot-swaps.

Can I switch between PLA and ABS?

Yes. Press the 'M' button below the LCD to change modes, then fine-tune the temperature in 1°C steps anywhere from 160°C to 230°C.

Is it cordless?

No, it's corded. Steady power keeps the temperature consistent during long sessions. It runs on a 5V/2A USB supply through the included power cord.

What if it doesn't work for us?

You get a 30-day money-back guarantee. If it doesn't flow smoothly or feel right in your hand, send it back for a full refund. It's also covered by a 2-year warranty against motor and heater faults.
