I had fun playing with the AFUNTA 3D Printing Pen and I progressed quickly. Several videos are available for beginners, but I stumbled through on my own. The attached photo shows my rapid growth from what I thought was to become a butterfly to something that actually looks like a butterfly, then a pedaless bike. The kit came with enough strands of plastic to create quite a few projects, but only in 3 colors. There are loads of colors available. I quickly learned to control the variable speed and the extrude and extract buttons. Threading the machine was super simple and fairly quick. The attached cord is a bit short, but an extension cord was quickly found. The projects dry/cool quickly. The entire experience was a blast and I look forward to creating more when I buy more colors of the strands.
I received this product at discounted rate in exchange for my honest and unbiased review.
