# 3D Print Meetup Challenges # 3D Print Meetup Challenges
## October 2025 Challenge: "Is it Glass or Clearly Natural?" Welcome to our monthly 3D printing challenges! Each month features a unique theme designed to test different aspects of 3D printing skills, from material handling to design innovation.
### Challenge Overview ## Active Challenge
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. ### October 2025: "Is it Glass or Clearly Natural?"
### Challenge Rules **Theme**: Transparency and clarity testing with 3D Fuel "Clearly Natural" filaments
#### Materials & Constraints **Key Details**:
- **Filament**: 3D Fuel "Clearly Natural" - Available in two variations: - **Model**: 25mm diameter × 50mm height cylinder in vase mode
- PCTG (Polyethylene Terephthalate Glycol) - **Materials**: 3D Fuel "Clearly Natural" PCTG or PLA
- PLA (Polylactic Acid) - **Focus**: Maximum transparency and print quality
- **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)

- **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
