This 3D printer pen won’t be making perfect amazing prints — but it WILL be great for adding electronics and components quickly to clothes!
It’s a fantastic rapid prototyping tool that I’ve used extensively with students in wearable tech workshops. The pen lets you affix components directly to fabric — sensors, battery holders, small boards — without sewing or gluing. With some care, you can remove the electronics afterward too, so you won’t damage your components or clothes.
If you want a more permanent solution, just use more TPU to really lock it in place. Get creative and make beautiful designs too!
Why It Works So Well for Wearables
TPU (thermoplastic polyurethane) is slightly flexible and presses into fabric fibres for a secure hold
Bonds to most fabrics, foam, and neoprene without adhesives
Peels off cleanly when you want to reuse components
Great for holding wires in place along seams or across panels
Students love it — fast, forgiving, and satisfying to use
Classroom & Workshop Use
In my wearable tech classes, students used this pen to mount components onto jackets, gloves, and bags in minutes. It’s especially useful when you want to prototype quickly without committing to a permanent build — perfect for iterating on designs before sewing everything down.
