Das Ergebnis ist ein mechanisch schwaches Teil, das unter Belastung auseinanderbricht. Im Gegensatz zu Delamination (sichtbare Risse) können sich Schichten auch unsichtbar schlecht verbunden haben.</p><h3>Hauptursachen &amp; Lösungen</h3><table class="tbl"><thead><tr><th>Ursache</th><th>Symptom</th><th>Lösung</th></tr></thead><tbody><tr><td>Temperatur zu niedrig</td><td>Schichten trennen sich bei Biegung</td><td>+5–10°C erhöhen</td></tr><tr><td>Druckgeschwindigkeit zu hoch</td><td>Risse zwischen Layern</td><td>Speed um 20% reduzieren</td></tr><tr><td>Schichthöhe zu groß</td><td>Sichtbare Lücken zwischen Layern</td><td>Max 75% des Düsendurchmessers</td></tr><tr><td>Zu viel Kühlung</td><td>Schichten verbinden sich nicht</td><td>Fan Speed reduzieren</td></tr><tr><td>Feuchtes Filament</td><td>Blasen + schlechte Haftung</td><td>Filament trocknen (65°C, 6h)</td></tr></tbody></table><h3>Temperatur korrekt einstellen</h3><p>Die Drucktemperatur ist der häufigste Grund für Layer Separation. Als Faustregel gilt: Die Schichten müssen heiß genug aufgetragen werden, damit das Material mit der darunterliegenden Schicht verschmilzt.</p><ul><li>PLA: 200–220°C — bei Separation auf 215°C erhöhen</li><li>PETG: 230–245°C — unterschätzt oft; 240°C ist ein guter Startpunkt</li><li>ABS/ASA: 240–260°C — Enclosure notwendig, sonst kühlt Material zu schnell ab</li><li>TPU: 220–235°C — langsam drucken, Kühlung reduzieren</li></ul><div class="tip"><strong>Tipp:</strong> Einen Temperatur-Tower drucken (Temperature Tower) um die optimale Temperatur zu finden. OrcaSlicer hat diesen Test integriert.</div><h3>Schichthöhe &amp; Düsendurchmesser</h3><p>Die Schichthöhe darf maximal 75–80% des Düsendurchmessers betragen. Bei 0,4mm Düse also maximal 0,3mm Schichthöhe. Wird diese Grenze überschritten, kann das Material die darunterliegende Schicht nicht mehr vollständig benetzen.</p><ul><li>0,4mm Düse → max. 0,3mm Schichthöhe (empfohlen: 0,2mm)</li><li>0,6mm Düse → max. 0,45mm Schichthöhe</li><li>0,8mm Düse → max. 0,6mm Schichthöhe</li></ul><h3>Kühlung richtig balancieren</h3><p>Zu viel Kühlung verhindert, dass Schichten miteinander verschmelzen. Besonders bei ABS und ASA sollte die Kühlung stark reduziert oder komplett deaktiviert werden. Bei PETG reichen 30–50% Fan-Speed.</p><ul><li>PLA: 80–100% Fan — keine Layer Separation durch Kühlung</li><li>PETG: 30–50% Fan — mehr kühlt schlechtere Haftung</li><li>ABS/ASA: 0–20% Fan — Enclosure verwenden</li><li>TPU: 30–60% Fan — je nach Härtegrad</li></ul><h3>Feuchtes Filament erkennen &amp; trocknen</h3><p>Feuchtes Filament zischt und knistert beim Drucken (durch verdampfendes Wasser). Neben Layer Separation entstehen Blasen, raue Oberflächen und Stringing. Lösung: Filament vor dem Druck trocknen.</p><ul><li>PLA: 45°C, 4–6h im Trockner oder Backofen</li><li>PETG: 65°C, 4–6h</li><li>ABS/ASA: 80°C, 4–6h</li><li>TPU: 55°C, 6–8h</li></ul><div class="tip"><strong>Langzeitlösung:</strong> Filament in luftdichten Boxen mit Silica-Gel lagern.
