Very long shot, but… does anyone have an arducam IMX519 or one of the 64mp modules lying around that they’d be willing to sell? Earliest I can get one delivered is midweek and there are no local stores.
I’ll preface this by saying I’m by no means an expert in 3D printing and I’m not an engineer by trade. Also worth adding that I’m not here to stoke any debate or to argue that CF filaments are “better” or worse.
I’ve been printing various filaments through an Elegoo CC the last 6 months and it’s bomb proof - PETG, PLA, TPU, Paht straight out of the drier. I’d been printing with a lot of PETG-CF through a 0.6mm nozzle not for mechanical properties but for ease of printing and matt finish, and finally got around to trying Elegoo Paht-CF earlier today.
I’ve read a lot here about how CF filaments are “the next asbestos” and ran a room-sized HEPA (25m2) next to the machine (it’s running in an open space to not too concerned about ventilation). I’ve got a microscope and was curious about the CF in the filament, so attached are various photos of a full print (0.24mm layer height) and of a raw extrusion at 0.6mm. You can see clearly in the raw extrusion how the CF fibres would act as a skin irritant, but despite grinding it into the skin on my inner wrist at the resolution of this microscope there’s no obvious penetration of the outer epidermis or “microneedles” that I can see. The tiny black dots left afterwards appear to be dust and are removed easily by a wet tissue.
I’ve got two chicken breasts in the fridge, Paht-CF, PETG-CF, and access to microscopy and SEM. I’m happy to experiment if anyone has any suggestions on how to quantify how well the fibres lodge from finished surfaces, handling brim/supports etc, but from my albeit limited take the “microneedles” comments from handling CF filaments seem excessive…
