Best Practices for 3D Printing Brick Parts
- Use PLA or PETG filament for strong, snap-fit connections
- Ensure proper layer adhesion — test print a single stud first before full builds
- Choose a layer height of 0.12–0.16mm for a good balance between quality and print speed
- Print with 0.2mm walls or higher for durable interlocking bricks
Materials and Tools
- PLA or PETG filament (1.75mm)
