3DPrinting

Hello 3d printer fans and makers. I currently have an a1 mini and have been putting it through its paces over the last several months. Ive probably used 5kg of filament and have maybe a few hundred hours of prints on it. I love the little machine, its a work horse. But it cannot print most engineering materials and Im looking to branch into more exotic prints and get myself a bigger build volume.

My first thought was getting the a1 with ams for multifilament printing and then I would have an ams I could use with either printer, but upon ruminating on the subject multifilament printing this way really seems to be such a gimmick and if I really want to do it there's always stop code and manual filament switching. Plus its another bed slinger with the only real change being the larger build volume.

So that brings me to the Qidi Q1 Pro. All the reviews really talk it up, I like that its built on klipper and an open ecosystem (-1 for Bambu), the hotend max temp, the heated champer, the larger build plate, and the price? All seems like a big win to me.

My current plan is buying the printer along with a filament dryer, I dont really want to get their drybox attachment, a smooth build plate, some CF something filament, and 0.6mm nozzle as accessories.

Do you all have any thoughts on polydryer, if the 3 x-plus might be something to consider if I really want a bigger build plate than what the Q1 pro offers, or if there might be another printer for me to consider in the $500-700 range. Also, any recommendations on filaments I might want to try with a heated chamber, 100C build plate, and 350C capable hot end? Im leaning towards something nylon and/or carbon fiber... maybe PA-CF? lol.

Anyways, any input is appreciated. Thanks!
