Pros & Cons
Anycubic Wash and Cure 3
Pros
- Combines the two resin post-processing steps most beginners underbuild: controlled washing and consistent curing.
- A dedicated station reduces the messy container shuffle that spreads uncured resin around a desk.
- Clear fit for small-format resin printers where a full industrial workflow is unnecessary.
- Better safety habit builder than improvising with random jars and inconsistent UV exposure.
Cons
- Does not replace gloves, eye protection, ventilation, or resin handling discipline.
- Wash-and-cure size must be checked against the largest build volume you actually print.
- A cleaner station can still become contaminated if tools and lids are not separated.
SUNLU S4 Four-Spool Filament Dryer
Pros
- Four-spool capacity makes it the cleanest single purchase for AMS-style benches, color swaps, and households with several open rolls.
- Active heat plus circulation solves the two-part drying problem: warming the spool and moving humid air away from the filament surface.
- Print-through workflow reduces the chance that a dried nylon, TPU, or PETG spool immediately reabsorbs moisture while a long job runs.
- The higher price is easier to justify when you would otherwise buy two single-spool dryers plus separate dry boxes.
Cons
- Overkill for a one-printer PLA bench where a sealed storage box and occasional single-spool dryer would do the job.
- Large footprint demands a real bench position, not a corner shelf.
- Multi-spool dryers do not replace labeled dry storage; partial rolls still need sealed long-term storage after the print.
Our Verdicts
Anycubic Wash and Cure 3
The Anycubic Wash and Cure 3 is the resin workflow product we would put in front of almost every small-printer beginner. It does not make resin harmless, but it turns post-processing into a repeatable station instead of a messy ritual spread across the whole bench.
SUNLU S4 Four-Spool Filament Dryer
The SUNLU S4 is the best launch pick for a printer owner who has moved past one open PLA roll and now needs an actual humidity-control station. It is not the cheapest way to dry a spool, but it is the most coherent way to keep several filaments usable, print from the box, and stop treating wet PETG or nylon as a printer-tuning mystery.
