Your Complete Guide to the Layer Logic Design Challenge

Dive into the details of the Layer Logic Design Challenge! This guide lays out everything from design constraints and DFAM guidelines to deliverables and judging criteria.


The Challenge

Competition participants must create a flat-pack stool using only PLA, incorporating innovative joinery for tool-free assembly.

Design Constraints

1. Design Specifics: Your submission must be designed for additive manufacturing using only PLA material. Ensure your design is optimized for 3D printing.

2. Assembly Requirements: The design should be flat-packed, requiring no additional hardware or tools for assembly, utilizing only PLA.

3. Color Options: You may use up to two colors per design. The available colors are white, black, and gray. Possible combinations include all white, all black, all gray, white+black, white+gray, and black+gray. More specific colors may be specified in the renders, but only these colors may be used in the prototype.

4. Size Constraints for Parts: Each individual part of your design must fit within a 14 x 14 x 14-inch build volume. Single parts may be split and put back together, however this must be factored into the engineering and not affect the stability of the stool.

5. Overall Size Limitation: The complete assembly of the stool must not exceed 18 inches in height.

6. Weight Capacity: Your design must support a minimum weight of 180 lbs.

7. Infill Specification: The infill percentage for your design should not exceed 30%.

DFAM Guidelines

1. Material Specification: Use only 1.75mm PLA filament for your designs.

2. Printer Capacity: Ensure your design fits within the maximum build volume of the XL Prusa, which is 355 x 355 x 355mm.

3. Joinery Techniques: Design mating parts that fit together well. Remember to include proper joinery methods in your submission.

4. Tolerances: Account for manufacturing tolerances to ensure parts fit together as intended.

5. Orientation: Consider the orientation of the part during printing to minimize the need for supports and maximize structural integrity.

6. Supports: Strategically plan where to place supports to prevent overhangs and ensure easy removal without damaging the part. Avoid areas where support scarring could compromise the design.

7. Dimensional Accuracy: Keep in mind the limitations of FDM printing for maintaining dimensional accuracy.

8. Material Behavior: Design with material expansion and shrinkage in mind to ensure the final dimensions are accurate.

9. Build Plate Preparation: Leave a border around the build plate to avoid the model sticking too close to the edge, ensuring stability during printing.

10. Surface Area Considerations: Maximize the surface area in contact with the build plate to enhance stability during the printing process.

11. Multi-color Designs: For multi-color prints, design each color area as a separate body to ensure precise color alignment.

12. Exporting Designs: When exporting your files, maintain the position to ensure the alignment of multi-part or multi-color components remains consistent.


1. 3D Model Formats: Submit your 3D models in STL, STEP, or OBJ formats. Ensure compatibility and precision in your submissions.

2. File Organization: Provide one file that includes the full assembly of your design. Additionally, export all individual bodies as separate files without altering their positions to maintain alignment.

3. Context Renders: Include up to five JPEG images showing your design from various angles to give context and enhance understanding of your submission.

4. G-code Submission: Provide the G-code of your model slice to specify the orientation of printing, infill rate, and types and locations of supports. This helps in understanding your choices for print preparation.

5. Title and Description: Clearly title your submission and provide a detailed description of the stool design, emphasizing unique features and design rationale.

Judging Criteria

1. Design for Additive Manufacturing (DFAM):
- 3D Printing Efficiency: Is the design optimized for 3D printing with minimal material waste and print time?
- Post-Processing: Assess the ease and time required for post-processing. Is the design suitable for mass production?
- Material Usage and Print Time: Detail the total print time and material usage for all components.

2. Manufacturing Capacity:
- Printer Capacity Utilization: How many parts of the product can fit in one printer, and how many printing sessions are needed per product?

3. Functionality and Market Fit:
- Multifunctionality: Does the design serve more than one purpose?
- Market Niche: Is the product designed for a specific or broad market? Does it address a unique or general need?

4. Context and Market Value:
- Versatility: Can the design be used in multiple spaces or aesthetics, or is it tailored for a unique setting?
- Target Audience: Is the design intended for the general population or a specific demographic group?

5. Assembly and User Experience:
- Joinery and Assembly: How intuitive and efficient is the assembly and disassembly process? Does the design effectively flat-pack?
- Ergonomics and Appeal: Is the stool ergonomically designed to be comfortable and appealing? Consider if the design is thought-provoking, comforting, intriguing, nostalgic, or visionary.

Joey Zeledón

Designer Joey Zeledón Studio

Joey Zeledón is a designer who helps objects find their purpose in life. They do this by creating aspirational narrative identities – sticky stories that drive meaning – for object archetypes. Is it just a printer? or could it be furniture that prints? Is it just a coffee maker? or could it be a barista in your kitchen? Is it just a clothes hanger? Or could it be a closet you can sit on? In 2022, they founded a design studio based on this approach, creating purposeful objects for people and market differentiation for clients. Prior to starting their own studio, Joey brought dozens of products to market from shoes and furniture to housewares, consumer electronics and consumer packaged goods during their 15-year career working for Clarks, Continuum, Smart Design, Steelcase and HP. Their designs have won 40+ awards and have been featured in leading publications. Joey is a proud RIT alum.‍
