My Tech Fun put two IPCON polyphthalamide filaments, distributed by Polymaker, through printing and pull tests on a scale rig.
The channel recorded four tensile pull results in the same test sequence: 164.2 kg and 197.3 kg (15:43), then 407.6 kg and 245.8 kg (15:53). The video does not show on screen which two numbers belong to PPA-GF and which belong to PPA-CF, so the pairing can’t be confirmed from what’s visible in the footage. What’s clear is the spread: the four breaks range from 164.2 kg at the low end to 407.6 kg at the high end, a difference of better than 2.4x between the weakest and strongest sample pulled.
Both materials share the same processing window: nozzle temperature 280-310°C, bed 100-120°C, drying at 100-140°C for 10-14 hours. The printed spec card at 0:21-0:22 shows a 0.8 mm nozzle size and a top speed of 250 mm/s. Filament diameter is 1.75mm ±0.05mm, sold in 750 g spools.
| Spec | Value |
|---|---|
| PPA-GF price (750 g) | $64.99-$111.99 across listed vendors |
| PPA-CF price (750 g) | $114.74-$149.99 across listed vendors |
| Modulus range shown | 37-65 GPa |
| Nozzle temp | 280-310°C |
| Bed temp | 100-120°C |
| Drying | 100-140°C, 10-14 h |
| Nozzle size | 0.8 mm |
| Max speed | 250 mm/s |
The channel also ran a drying/moisture-loss test, tracking spool weight drop from 955.30 g down to 950.86 g over repeated cycles (2:55), and a shrinkage check on printed parts measuring 79.94 mm and 79.95 mm (14:22-14:26). A bend/brittleness check logged failure angles of 30°, 40° and 41° (5:20-5:44).
No sample count or test standard (ASTM/ISO) is stated on screen, and the printer, nozzle brand or bed surface used for the pull-test parts isn’t identified. The video’s title calls one of the two filaments the strongest the channel has tested, but the on-screen numbers don’t attach that claim to a named grade, so these figures describe one tester’s rig rather than a lab-certified, per-material result.
