How Are There No Layer Lines?" - -Can you achieve the smoothest, most layer-line-free surface finish possible? This challenge pushes your printer tuning, slicer settings, and material knowledge to the limit. The goal is simple but difficult: create a 25mm cube with 2 walls and no top that looks so smooth, people question whether it was actually 3D printed! - -## Challenge Details - -### Materials & Constraints - -- **Filament**: 3D Fuel filament (any type: PLA+, Pro PLA+, PCTG etc.) -- **Nozzle Requirement**: Must use a 0.4mm nozzle (REQUIRED) -- **Estimated Filament Usage**: Approximately 3 grams (for reference only) -- **Model Specification**: - - **Dimensions**: Exactly 25mm x 25mm x 25mm cube (REQUIRED) - - **Wall Count**: Exactly 2 walls (no more, no less) (REQUIRED) - - **Top Layers**: 0 (no top surface) - - **Bottom Layers**: Standard (as needed for proper adhesion) - - **Infill**: 0% (hollow interior) -- **Print Mode**: Standard FDM/FFF printing (no resin printing) - -### Competition Categories - -- **Smoothest Surface**: Best overall surface finish with minimal visible layer lines straight off the printer -- **No post-processing allowed** - cubes must be judged as-printed - -### Judging Criteria - -1. **Layer Line Visibility** (100%): The appearance and visibility of layer lines - less visible is better - - All cubes must meet basic challenge requirements (25mm cube dimensions, exactly 2 walls, 0.4mm nozzle, no post-processing) - - Winner is determined solely by smoothness of surface and minimal layer line appearance - -### Submission Requirements - -- **Physical Model**: Bring your printed 25mm cube to the December meetup for judging -- **Dimension Verification**: Must be exactly 25mm x 25mm x 25mm -- **Wall Count Verification**: Must show exactly 2 walls when inspected -- **Nozzle Verification**: Must be printed with 0.4mm nozzle -- **Settings Documentation**: Share your winning settings (layer height, temperature, speed, cooling, techniques) -- **Process Notes**: Brief description of your approach - -## Timeline - -- **Challenge Announcement**: November 12, 2025 (at November meetup) -- **Submission Deadline**: December 10, 2025 (at December meetup) -- **Judging Period**: December 10, 2025 (during December meetup) -- **Winner Announcement**: December 10, 2025 (end of December meetup) - -## Creating the Cube Model - -### Using the Provided Model - -**Download the pre-configured cube:** - -- **File Location**: [Challenge Files/November2025/Cube.3mf](https://gitea.ercomputersolutions.net/espoon/3DPrintMeetup/src/branch/master/Challenge%20Files/November2025/Cube.3mf) -- **Pre-configured**: Already set to 25mm x 25mm x 25mm with 2 walls and no top -- **Ready to slice**: Import into your slicer and adjust settings for your printer - -### Using Bambu Studio - -**Step 1: Add Primitive** -1. Open Bambu Studio to a new project -2. Right-click on the build plate -3. Select "Add Primitive" -4. Select "Cube" - -**Step 2: Resize the Cube** -1. Click to resize the cube -2.
