Review on 🖨️ Gizmo Dorks Acetal Filament: Advanced 3D Printing Supplies for Additive Manufacturing by Gilbert Pfaff

I bought this filament to create custom cable guides, bearings, etc. It took a few grams to come up with a successful printing method for my FLSUN QQ-S Pro delta printer with PEI platform and heated and ventilated body, but I settled on the following: Base: Freshly cleaned, with 4 layers of glue stick - 120°C - Use wide-brimmed nozzle: 222°C (Saw better flow than 220°C, with a good cushion under 230°C) Z-bias: sticks firmly to paper, resists pressure – wants to be pressed into a hot bed first Layer: 0.3 mm thick at <=15 mm/sec. at 100% flow, 0% fan Remaining layers: 15 mm/sec. 80% Flow, 70% Fan At print temperature, it behaves very similar to PETG i.e. viscous and stringy and is why 80% flow avoids staining, but there is still some elongation in the elongation test of new parts. Use the edge for everything! So far, the edges have come off slightly, as with PLA and ASA. I had a very small part that printed well with both the 95°C and 110°C bed, but at 120°C warping didn't seem to be an issue. YMMV of course! I didn't notice any odor when printing, but I used my VOC scrubber anyway. Check out the attached image. The bed has cooled down to 41°C at the time of the picture and you can hear clicks, crackles and pops when you let go if the bed is below 90°C. I've found that it's best to let it cool on the bed to a temperature close to room temperature. Some of the same parts could be printed successfully in the shadow of their predecessors, but for new parts you'll probably have to start over. The properties of the printed material (tough and amazingly flexible in thin layers) are such that it seems to be a good candidate for custom cable ties, maybe even better than the nylon I have for this purpose! As this is a limited use material 200 grams will likely last a long time but if the above printing method continues to work when I print a wider variety of parts I will purchase more as needed.
