PA - Polyamide
Polyamide or Nylon as a brand name are common in everyday house hold items like garments, shells for power tools and automotive parts. Polyamide filaments are typically used for housings for various components or for its tolerance to withstand thermal loads with minor deflection. Corresponding to its use in injection molding Polyamide filaments are often found with additives such as glass fibers or carbon fiber, these additives enable Polyamide filaments to print easier then their unfilled counterparts and filled filaments tend to handle higher loads then their unfilled counterparts.
Advantages
- Chemically resistant.
- Abrasion resistant.
- Impact resistant.
- Stable at a wide range of temperatures.
Disadvantages
- Tricky to print.
- Absorbs moisture quickly.
- Creeps easily.
- Needs post processing prior to use(water immersion).
Variants
Standard guidance on additives applies.
Baseline Printing Recommendations
These numbers are provided as a baseline, and need adjustment and calibration for your specific printer/filament/color combination.
Variant | Hotend Temperature | Heatbed Temperature | Chamber Temperature | Optimistic Usable Temperature | Drying Temperature |
---|---|---|---|---|---|
PA6 | 270 | 110 | 65 | 70 | 80-90 |
PA12 | ? | ? | ? | ? | ? |
PA66 | ? | ? | ? | ? | ? |
Other notes
PA requires extensive preparation of the build plate so it will not warp. Certain glues that are not PVA family based are recommended. Most PA filaments will contain an additive like glass fibers with a typical concentration of 30% or carbon fibers with an unknown percentage of concentration.
