How Are There No Layer Lines?" -Experience the clarity of 3D Fuel's "Clearly Natural" filament in this transparency-focused challenge! Participants will attempt to create the clearest possible print, testing the limits of clear filament printing techniques. +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 "Clearly Natural" - Available in two variations: - - PCTG (Polyethylene Terephthalate Glycol) - - PLA (Polylactic Acid) -- **Maximum Filament Usage**: 250g per entry -- **Model Specification**: Cylinder - 25mm diameter x 50mm height -- **Print Mode**: Vase mode (approximately 6 grams of filament) + +- **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 × 25mm × 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 -- **PCTG Division**: For prints using Clearly Natural PCTG -- **PLA Division**: For prints using Clearly Natural PLA -- **Overall Winner**: Best clarity across both divisions + +- **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. **Clarity & Transparency** (40%): How clear and glass-like is the final print? -2. **Print Quality** (30%): Surface finish, layer adhesion, and overall structural integrity -3. **Technique Innovation** (20%): Creative printing techniques to maximize transparency -4. **Challenge Adherence** (10%): Following material constraints and using supplied model + +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 -- **Model Compliance**: Cylinder must measure 25mm diameter x 50mm height -- **Vase Mode**: Must be printed in vase mode (single perimeter wall) -- **Weight Verification**: Should use approximately 6 grams of filament -- **Documentation**: Include photos showing transparency (with light sources) -- **Settings Documentation**: Share printer settings used (layer height, temperature, speed, etc.) -- **Process Notes**: Brief description of techniques used to achieve clarity + +- **Physical Model**: Bring your printed 25mm cube to the December meetup for judging +- **Dimension Verification**: Must be exactly 25mm × 25mm × 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**: October 1, 2025 -- **Model Specification Released**: October 13, 2025 -- **Submission Deadline**: October 28, 2025 -- **Judging Period**: October 29-30, 2025 -- **Winner Announcement**: October 31, 2025 -## Creating the Cylinder Model +- **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://meetup.fargo3d.com/Fargo3d/3DPrintMeetup/src/branch/master/Challenge%20Files/November2025/Cube.3mf) +- **Pre-configured**: Already set to 25mm × 25mm × 25mm with 2 walls and no top +- **Ready to slice**: Import into your slicer and adjust settings for your printer ### Using Bambu Studio diff --git a/Home.md b/Home.md index 1f9e8e0..c8a3652 100644 --- a/Home.md +++ b/Home.md @@ -22,7 +22,7 @@ Welcome to the official wiki for our monthly 3D printing meetup!
