Erste Maßnahme: Temperatur in 5°C-Schritten senken bis Stringing nachlässt. Grenze: Schichthaftung darf nicht schlechter werden.</p><ul><li>PLA: 195–210°C wenn Stringing auftritt</li><li>PETG: 230–235°C (PETG neigt stark zu Stringing)</li><li>TPU: 220–228°C</li></ul>\n<h2>Schritt 2: Retraction einstellen</h2><p>Retraction zieht das Filament beim Travel-Move zurück damit keine Schmelze aus der Düse tropft.</p><table><thead><tr><th>Extruder-Typ</th><th>Start</th><th>Maximum</th></tr></thead><tbody><tr><td>Direct Drive (Bambu, Prusa, Ender S1)</td><td>0,8mm</td><td>2,5mm</td></tr><tr><td>Bowden kurz (&lt;400mm)</td><td>3,5mm</td><td>6mm</td></tr><tr><td>Bowden lang (&gt;400mm)</td><td>5mm</td><td>8mm</td></tr><tr><td>TPU / Flexibel</td><td>0,5mm</td><td>1,5mm</td></tr></tbody></table>\n<div class="tip"><strong>Achtung:</strong> Zu viel Retraction verursacht Unter-Extrusion und Gaps.
