This pen unfortunately didn't work well. It is a durable pen. However, after one or two uses it started to not get hot enough to fully melt the refill and had a very strong smell. It didn't work well even in the slow mode. The 3D prints that were able to be printed were durable enough to be thrown and not break.

Great crafty device to make your ideas come alive. I enjoyed making different little projects. Also made my grandsons names for some of their toys and baskets

The 3Doodler Flow is a printing pen that keys you build and draw 3D structures freestyle or using stencils. So cool! The kit includes the pen, 8 different colors spools, power adapter, and stencil sheets. Super easy and fun!
