PA6-CF beats PA12-CF dry at 140 MPa and twice the stiffness, then humidity cuts it to 56% strength and a third of stiffness while PA12-CF holds.
3D Printing
Printers, hotends, slicers, and filament, judged on what they change about the print rather than the spec sheet.
Humidity flips the winner between PPA-CF and PA6-CF
PPA-CF vs PA6-CF differ on strength, layer bonding, heat and moisture, and the pick-by-job verdict flips the moment humidity enters the room.
Nozzle swapping replaces the purge tower on Creality's K3
Creality KliTek swaps nozzles instead of purging, arriving on the K3 in 2026. See why nozzle-swap systems drift and why soft TPU is the real driver.
The AMS HT dries nylon at the 75°C the AMS 2 Pro misses
Nylon filament drying needs 75°C, and the AMS HT reaches 85°C while the AMS 2 Pro caps at 65°C, missing the floor that pulls moisture from PA6-CF.
30 minutes at 100°C nearly doubles HT-PLA Pro's heat limit
HT-PLA Pro annealing raises heat deflection from 56.3°C to 107.6°C in 30 minutes, turning the 150°C softening claim into real load-bearing heat.
All five ingredients in PLA Pure clear EU 10/2011 rules
PLA Pure food-contact safety rests on all five ingredients passing EU 10/2011, but the certification covers the filament, not your printed cup.
