Asa Filament Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

OVERTURE is the best-performing asa filament brand in July 2026, moving 8,000 units across 4 ASINs for 48.5% of Top 10 volume. SUNLU follows with 4,000 units (24.2%), ahead of Polymaker on 2,800 units (17.0%).

With 5 brands splitting the Top 10 and 89.7% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $13.99 to $22.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. On the growth side, B0B18CQGQJ leads positive momentum with ▲ 300.0% MoM growth on 400 units, with B0FBRK4LNR close behind at ▲ 300.0% MoM on 200 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
