3D PRINTING TROUBLESHOOTING

On this page, we’ve gathered common 3D printing issues with Paragami designs and provide practical tips to ensure smooth, successful prints.

001. GAPS IN THIN OR SINGLE-PERIMETER WALLS


  • This issue most commonly affects Coral Sponge templates and other designs with thin, organic walls.


    Some slicers struggle to generate continuous perimeters when a wall transitions between:
    • Thicker sections (2 or more perimeters)
    • Thinner sections (1 perimeter or near the slicer’s minimum wall width)

    Instead of creating one continuous closed perimeter first, then adding extra perimeters where space allows, some slicers generate two perimeters simultaneously in thick areas, then a separate single perimeter in thin areas.

    This leads to:

    • Gaps in the wall
    • Disconnected perimeters
    • Weak or unstable prints

    Additionally, if a wall is thinner than the slicer’s minimum wall width, the slicer may skip generating a perimeter entirely.

  • What We’re Trying to Achieve (The Goal)

    Regardless of slicer, the goal is always the same:

    ✔ A continuous, closed perimeter

    ✔ At least one perimeter generated everywhere the wall exists

    ✔ Smooth transitions between thin and thick wall sections

  • How PrusaSlicer Handles This

    PrusaSlicer generally produces the correct behavior by default.

    It:

    • Generates a fully closed perimeter first
    • Adds extra perimeters only where wall thickness allows
    • Handles thin-wall transitions more predictably

  • Suggested Adjustments for

    BAMBU Studio & ORCA Slicer


    Bambu Studio and Orca Slicer can achieve similar results, but often require manual tuning.

    ⚠️ These settings are suggestions, not guarantees.
    Every model/block is different, and you may need to tweak values.

  • Enable Advanced Settings:

    To get access to extra settings in Bambu Studio / Orca Slicer , make sure to enable Advanced or Expert mode.

  • Core Wall & Transition Settings

    • Wall Generator: Arachne
    Dynamically varies line width to better fill thin and variable walls


    • Wall Transitioning Filter Margin: 1000%
    Allows more aggressive smoothing between thick and thin walls


    • Wall Transition Length    : 150%
    Extends the blending distance when changing wall thickness

    • Minimum Wall Width: 150%
    Forces generation of a perimeter even for very thin walls

    • Minimum Feature Size: 50%
    Prevents small wall features from being discarded

    • Seam Position    : Random
    Avoids visible seam alignment and reduces weak points

    • Ensure vertical thickness: Enabled


    These settings     work in combination. Changing only one may not be enough.

  • Additional Techniques If Gaps Persist

    If the above settings don’t fully solve the issue, try one or more of the following:

    Thin Wall & Geometry Adjustments

    • Enable “Ensure vertical shell thickness”
    • Quality / Line Width / Outer wall:
      Example-Reduce : 0.45 mm → 0.30 mm


      In testing, I was able to successfully print a single block with a hole just by reducing the line width, while leaving all other settings at default (Wall Generator: Classic).

  • Orientation & Print Strategy

    Reorienting the model can significantly improve thin-wall printing. Tilt the model and enable supports so the problematic wall prints at a slight angle—this effectively increases the wall’s printable width and helps the slicer generate a continuous perimeter.

    For low-rise or shallow-angle features, hollow blocks often print more reliably than solid ones. You can drag, drop, and rotate blocks to find an optimal rise angle; this approach works for both single blocks and grouped layouts (such as 4×4 arrays—split the group after rotating if needed).

    Adjust the rotation based on your printer’s cooling performance and print speed. Fine-tune slicing accuracy by tweaking Detect Thin Walls, Shell Thickness, and Extrusion Width as needed.

    When using supports:

    • Match the support overhang threshold angle to the model’s tilt
    • No infill is required for these supports
    • Limit support height using support enforcers to keep them only where necessary
