ASA dryer purchase decision
Which filament dryer can handle ASA?
ASA does not have one universal drying cycle. Polymaker specifies 70°C for 7 hours for its current ASA. Creality's material-family guide lists 65°C for 8–12 hours in a Creality dryer and 70–80°C for 8 hours in a blast dryer. The exact spool and method decide which dryer is sufficient.
A 70°C ceiling matches Polymaker's current ASA setting on paper and clears Creality's 65°C consumer-dryer reference. It does not clear the top of Creality's 70–80°C blast-dryer range. Do not substitute longer time at lower heat unless the exact filament maker provides that alternative.
Direct answers
The three questions that change the purchase
What temperature should ASA be dried at?
Use the exact product instruction. The official examples here span 65°C in a Creality filament dryer, 70°C for Polymaker ASA, and up to 80°C in Creality's blast-dryer guidance.
Is a 70°C filament dryer enough for ASA?
It matches some cited settings on paper. It remains below an 80°C instruction and offers no temperature headroom when the target itself is 70°C.
Can ASA be printed while drying?
Every dryer in this site's cited database documents a print-through path, but spool fit, feed routing, ventilation, and the exact manufacturer workflow still need confirmation.
Requirement before product
Two official sources create three useful thresholds
Polymaker ASA
Polymaker's current product wiki specifies 70°C for 7 hours. A dryer rated to exactly 70°C is a paper match with no stated headroom.
Official Polymaker ASA guidance ↗Creality ABS / ASA family guidance
Creality lists 65°C for 8–12 hours in a Creality filament dryer and 70–80°C for 8 hours in a blast dryer.
Official Creality drying guide ↗Interpretation: equipment type is part of the instruction. A consumer dryer setting and a blast-dryer range are not interchangeable just because both appear in the same manufacturer table.
Documented ceiling comparison
Which current consumer dryers clear 70°C and 80°C?
| Dryer | Stated maximum | Against 70°C | Against 80°C |
|---|---|---|---|
| Polymaker PolyDryer | 73°C | Clears on paper | Below requirement |
| Creality Space Pi Plus | 70°C | At stated maximum | Below requirement |
| SUNLU FilaDryer S4 | 70°C | At stated maximum | Below requirement |
| EIBOS Polyphemus | 80°C | Clears on paper | At stated maximum |
| Creality SpacePi X4 | 85°C | Clears on paper | Clears on paper |
| Bambu Lab AMS HT | 85°C | Clears on paper | Clears on paper |
| Bambu Lab AMS 2 Pro | 65°C | Below requirement | Below requirement |
| Creality Space Pi | 70°C | At stated maximum | Below requirement |
| SUNLU FilaDryer S2 | 70°C | At stated maximum | Below requirement |
| EIBOS Easdry | 65°C | Below requirement | Below requirement |
| EIBOS Cyclopes | 70°C | At stated maximum | Below requirement |
A 70°C system at a 70°C target must operate at its stated ceiling. That rating is not proof of uniform spool temperature.
Use the exact approved setting. Excess heat can deform filament or the supplied reel, especially when the spool material is not documented.
Drying capability does not resolve enclosure, emissions, ventilation, fire safety, printer compatibility, or part-performance requirements.
What to buy for
Temperature narrows the field; workflow chooses the unit
Reject insufficient ceilings.
Screen against the exact product and method. Treat an exact match as a narrow capability claim, not measured performance.
Count simultaneous spools.
One, two, and four-spool systems solve different printer and production workflows. Unused chamber volume is not a benefit.
Confirm print-through routing.
Check outlet count, tube path, spool rotation, timer behavior, and whether the maker permits continuous heated operation.
Plan dry storage.
A completed cycle can be undone by humid storage. Compare sealing and storage mode after temperature requirements are met.
Purchase decision
Resolve the dryer in this order
- 01Find the exact ASA data sheet.
Record the drying method, temperature, time, humidity instruction, and supplied-spool heat limit.
- 02Reject dryers below the documented cycle.
Do not replace temperature with more time unless the filament manufacturer explicitly permits that alternative.
- 03Compare the complete workflow.
Check capacity, outlets, timer length, controls, electrical requirements, support, storage, and regional warranty.
- 04Separate drying from printing safety.
Confirm the printer's enclosure and material support, provide appropriate ventilation, and follow all manufacturer safety instructions.
