The only thing more engaging than iPad

The 3D pen activates both the hands and the brain in a way screens simply can’t. By combining touch, movement, and spatial thinking, it engages more senses at once, keeping kids deeply absorbed. This hands-on mechanism creates a natural achievement loop — every shape built sparks dopamine, making focus last much longer than with passive screen time.

Builds problem-solving and creative skills

The 3D pen strengthens problem solving & STEM learning by turning abstract ideas into real, 3D models kids can touch and explore. This hands-on process trains problem-solving, creativity, and spatial skills in a way screens alone cannot.

Designed for kids, safe even on skin

Built for kids’ safety with a low-temperature mode that keeps the nozzle under 104°F. Both the tip and plastic can be touched with no burn risk, and certified safety standards give parents peace of mind. Unlike most 3D pens that run very hot and are only for ages 16+, this one is designed for younger creators.

Wireless operation

Built-in battery mean you can recharge in just 30 minutes and start drawing anywhere. Kids aren’t tied to a desk or outlet, making creativity portable and easy to take on trips, playdates, or school projects.

Got questions? We'd love to answer!

Is the Formini pen safe for children?

Yes — our pen is specifically designed with safety in mind. The tip remains cool-to-touch while extruding compared to other 3D pens on the market that reach very high temperatures.

How long does it take for the filament to warm up?

Typically about 30–60 seconds. An LED indicator will signal when the pen is ready.

How strong or durable are my creations?

Strength depends on how you build — thicker layers and slower drawing make sturdier parts. Very fine lines are more flexible and delicate.
