1975 Old style, I have been a software developer for about 30 years. I love 3D printing and especially cad modeling. I'm involved in a new home automation startup, online soon! And 3D printing will help me make box for my electronic parts. For now I'm having fun and practicing with my A1 Mini combo, great printer and kudos to Bambulab who made something difficult accessible to everyone, I hope to move on to something bigger soon. I love all technology in general.
