Hi, Im 12 years old and absolutely love 3d printing!!! I am so glad to be owning a Bambu A1, it is the best money I have ever spent! I love the fantastic idea about being able to design and then create anything I want. The a1 has amazing quality and has never been a problem. I used to own an Ender 3, but I felt it was to slow. Now I am saving up to buy an X1C, or even the new H2D.
