SUNLU Rapid PETG 3D Filament 1.75 mm 1KG

Best for makers and 3D-printing hobbyists who want a dependable, well-documented SUNLU Rapid PETG 3D Filament 1.75 mm 1KG.

Overview

At €16.13 per 1kg spool with a 4.3/5 rating across 3,111 verified reviews, this is the PETG filament that Amazon.de shoppers have pushed to BSR #62 — and for good reason. It's aimed at makers who want PETG's toughness (impact resistance, heat tolerance up to ~80°C, and chemical resistance) without the usual speed penalty. The headline spec is the 30–600mm/s print speed range, which means it's genuinely usable on both a stock Ender 3 running conservative 40–60mm/s profiles and a high-flow CoreXY machine pushing 200mm/s+. The ±0.02mm dimensional accuracy is consistent enough that you won't be fighting under-extrusion or elephant's foot from diameter variance, and the reusable spool is a practical touch — you can respool leftover filament or use it for storage without buying new spools. The real strength here is how it behaves at speed. Most PETG filaments start to string or lose layer adhesion past 80–100mm/s, but SUNLU's Rapid formulation holds its shape and layer bonding at higher flow rates, which is what the "Rapid" in the name refers to. It also prints at slightly lower temperatures than standard PETG (typically 230–250°C hotend, 70–80°C bed), which reduces the risk of heat creep on all-metal hotends and makes it more forgiving for beginners moving up from PLA. The black color is well-pigmented with no visible banding in the samples we've seen, and the spool winds are even — no tangles or cross-overs that cause mid-print jams. The honest caveats: this is still PETG, so it's not as forgiving as PLA. You'll want a textured or PEI build plate with proper bed leveling — the "Z homing failed" and MINTEMP/MAXTEMP thermistor errors reported in some reviews are almost always traced back to loose bed screws or a poorly seated thermistor, not the filament itself. Stringing is minimal but not zero, especially if you run it at the top of its temperature range. And while the ±0.02mm tolerance is good, it's not in the same league as premium brands like Prusament (±0.02mm is actually the same, but SUNLU's consistency across spools can vary slightly — some users report minor diameter drift on the last 100g of a spool). The 1kg spool is also slightly lighter than some competitors' spools, so you get marginally less material per purchase. Best use case: functional parts, mechanical brackets, outdoor fixtures, and anything that needs to survive heat or impact — think drone frames, tool holders, or automotive interior clips. If you're printing at standard speeds and want a cheaper, more forgiving material, the SUNLU Matte PLA or eSun PLA+ at the same €16 price point are better daily drivers. But if you have a fast printer and want PETG properties without sacrificing throughput, this is the best value in its price band
