Tungsten carbide nozzle vs hardened steel on Bambu's X2D: HRA 90 against HRA 74, about 50% more life on abrasive filament, and almost no retuning.
3D Printing
Printers, hotends, slicers, and filament, judged on what they change about the print rather than the spec sheet.
At Shore 68D the TPU for AMS keeps prints fast and clean
TPU for AMS runs a Shore 68D hard flexible through the Bambu AMS at up to 238 mm/s, resisting the jams, stringing and warping that stall soft TPU.
Polymaker Fiberon PPS-GF20 survives 236°C on a desktop
Polymaker PPS-GF20 hits a 236°C heat deflection after annealing and prints on a QIDI Plus4 or Bambu H2D with a 350°C hotend and the fan off.
Prusament PETG Recycled cuts spool CO₂ by 56 percent
Prusament PETG Recycled emits 2.55 kg CO₂ per kg against 5.85 kg for virgin PETG, a 56 percent cut at the same tolerance and print temperatures.
Stratasys PA6/66-GF30-FR meets EN 45545 rail fire rules
PA6/66-GF30-FR clears EN 45545-2 HL2 and FMVSS 302, so a printed rail handrail can be certified. See what UL-94 V0 demands, and what FR costs you.
ASA holds 80 percent impact where ABS fades in UV light
ASA vs ABS under UV light: ASA keeps over 80% impact at 2,000 xenon-arc hours while ABS drops below 50% by 500, and ASA resists acetone smoothing.
