eSUN PETG

eSUN PETG review: tougher than ABS, no enclosure needed, and cheap. Best print and bed temperatures plus tuning tips for clean PETG in 2026.

4.3/5

Polymaker PolyMide CoPA

Polymaker PolyMide CoPA review: a warp-free nylon that prints on a 30–50°C bed without a heated chamber. Tough engineering parts made approachable in 2026.

4.4/5

Prusament PETG

Prusament PETG review: ±0.02mm tolerance, batch QR data, and clean functional prints at 250°C. The PETG to reach for when accuracy matters in 2026.

4.6/5
