# 3D Print Meetup Challenges
|
||
|
||
## October 2025 Challenge: "Is it Glass or Clearly Natural?"
|
||
|
||
### Challenge Overview
|
||
|
||
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.
|
||
|
||
### Challenge Rules
|
||
|
||
#### 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 × 50mm height
|
||
- **Print Mode**: Vase mode (approximately 6 grams of filament)
|
||
|
||
#### 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
|
||
|
||
#### 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
|
||
|
||
#### Submission Requirements
|
||
|
||
- **Model Compliance**: Cylinder must measure 25mm diameter × 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
|
||
|
||
#### Evaluation Process
|
||
|
||
- **Transparency Test**: Prints will be evaluated under controlled lighting conditions
|
||
- **Comparative Assessment**: Side-by-side comparison with actual glass reference
|
||
- **Community Voting**: People's choice award for favorite clear print
|
||
- **Technical Review**: Expert panel assessment of print quality and technique
|
||
|
||

### Creating the Cylinder Model
|
||
|
||
#### 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 "Cylinder"
|
||
|
||
|
||
|
||
**Step 2: Resize the Cylinder**
|
||
|
||
1. Click to resize the cylinder
|
||
2. Uncheck "uniform scale" if checked
|
||
3. Set X and Y to 25mm
|
||
4. Set Z to 50mm
|
||
|
||
|
||
|
||
#### Alternative Methods
|
||
|
||
- **Fusion 360**: Create cylinder sketch, extrude to 50mm height
|
||
- **Tinkercad**: Use cylinder shape, adjust dimensions
|
||
- **FreeCAD**: Create cylinder with specified dimensions
|
||
- **Any CAD Software**: Simple cylinder 25mm diameter × 50mm height
