Editorial overview
Trending in r/3dprinting
The strongest rising or new signals by prevalence change: how much more often each entity appears in the current seven-day window compared with the previous seven, normalized by analyzed activity. A signal needs at least 5 distinct posts or comments in the current window. “New” means absent from the comparison window — not new to the world or to Reddit.

All signals for r/3dprinting are reported for the same exact windows; strength is a presentation aid, not a stored metric.

Explore the data
Exact published metrics for r/3dprinting. Rising and Falling compare the current seven-day window 2026-10-10 → 2026-10-16 with the previous seven days 2026-10-03 → 2026-10-09 ( complete UTC days; 12,303 current vs 5,429 comparison analyzed records). Signals appear only with at least 5 distinct posts or comments behind them — the current window for Rising, the comparison window for Falling; the CSV export still contains the complete published metric set. Most discussed uses the current analysis lookback (2026-09-17 → 2026-10-17) — frequency, never trending.

“New” means absent from the comparison window — not new to the world or to Reddit. All signals are automatically extracted and may be wrong; they are directional product signals, not causal claims.
