For a functional, leak-proof part like this printed in ABS on your Bambu Lab P1S, use the following settings. These are optimized for thread accuracy and structural integrity.<h3>Core Print Settings</h3><figure class="table"><table><thead><tr><th>Setting</th><th>Value</th><th>Logic</th></tr></thead><tbody><tr><td>Layer Height</td><td>0.2mm (Optimal)</td><td>Balance between speed and thread definition.</td></tr><tr><td>Wall Loops</td><td>5</td><td>Crucial for making the spout and cap walls water/air-tight.</td></tr><tr><td>Top/Bottom Shells</td><td>5 Layers</td><td>Ensures a solid seal where the spout meets the cap body.</td></tr><tr><td>Infill</td><td>40% Gyroid</td><td>Provides high strength without wasting material.</td></tr><tr><td>Internal Solid Infill</td><td>On</td><td>Set &#34;Internal Solid Infill&#34; to 100% for the first 5mm of the spout.</td></tr></tbody></table></figure>Export to Sheets<h3>ABS Material &amp; Bed Management</h3><ul><li>Bed Temperature: 90°C – 100°C (Textured PEI Plate recommended).</li><li>Enclosure: Keep the P1S door and top lid closed. Heat soak the chamber for 10–15 minutes before starting to minimize warping.</li><li>Cooling: Low (10-30%). High fan speeds will cause the ABS layers to delaminate (split), especially on the tall spout.</li><li>Brim Type: Outer Brim Only.<ul><li>Brim Width: 5mm – 8mm.</li><li>Brim-Object Gap: 0.1mm.</li><li>Rationale: Circular ABS bases are prone to &#34;shrinking&#34; and lifting at the edges. A wide brim is mandatory here.</li></ul></li></ul><h3>Orientation &amp; Supports</h3><ul><li>Orientation: Print cap-side down (widest part on the bed).</li><li>Supports: None. * The internal 38-400 threads are shallow enough for the P1S to bridge without support.<ul><li>The transition from the cap to the spout (fillet) is a natural overhang that the printer can handle.</li></ul></li><li>Seam Position: Aligned or Back. Avoid &#34;Random&#34; to prevent &#34;zits&#34; inside the threads which could cause cross-threading.</li></ul><h3>Critical Calibration Tip</h3>Since ABS shrinks by approximately 0.7% to 1.5%, if the cap is too tight on your jug, do not use &#34;XY Size Compensation.&#34; Instead, adjust the &#34;Internal Hole Compensation&#34; in Bambu Studio by +0.1mm or scale the entire model to 101% to account for the material contraction.
