This final project combines traditional Japanese design with modern digital fabrication to create a functional 3D incense diffuser. The project integrates the Genji Mon (源氏紋) pattern from Week 1's CAD work with 3D printing techniques from Week 4 to create a beautiful, functional object that bridges traditional craft and digital manufacturing.

The incense diffuser incorporates the intricate Genji Mon geometric patterns not only for aesthetic appeal but also for functional ventilation, demonstrating how traditional design principles can enhance modern product functionality.

• Cultural Integration: Combining traditional Japanese design with modern 3D printing technology
• Functional Art: Creating a beautiful object that serves a practical purpose
• Pattern Application: Using the Genji Mon geometry to create ventilation and aesthetic features
• Material Exploration: Testing different materials (resin, ABS) for optimal functionality
• Digital Craftsmanship: Demonstrating mastery of CAD design and 3D printing techniques

Cultural Significance

The Genji Mon (源氏紋) is a traditional Japanese family crest pattern with deep historical significance. The pattern represents the Genji clan, one of the most influential families in Japanese history, particularly during the Heian period (794-1185). Historical Context: • Origins: The Genji Mon pattern dates back to the Heian period and is associated with the Minamoto clan (源氏)
• Cultural Impact: Featured prominently in "The Tale of Genji" (源氏物語), considered the world's first novel
• Design Elements: The pattern typically features geometric arrangements representing different aspects of court life
• Modern Usage: Still used in traditional Japanese arts, textiles, and ceremonial contexts

Material Testing (Week 4)

The project required testing different 3D printing technologies and materials to determine the optimal approach for the incense diffuser.

ABS Printing (Prusa MK4S)

• Material: Prusament ABS (Black)
• Wall Thickness: 0.4mm (structural integrity for FDM)
• Advantages: High strength, heat resistance, durability
• Applications: Functional parts, mechanical components

Material Selection for Final Project

Based on testing, the final incense diffuser will use: • Primary Material: ABS for structural integrity and heat resistance
• Detail Elements: Resin for intricate pattern components
• Hybrid Approach: Combining both materials for optimal functionality

Vinyl Cutting and Sandblasting (Week 2)

To explore alternative applications of the Genji Mon pattern, the design was also tested on ceramic surfaces using vinyl cutting and sandblasting techniques. This process demonstrated the versatility of the pattern across different materials and manufacturing methods. Process Overview: • Vinyl Masking: Genji Mon pattern cut from vinyl as sandblasting resist
• Surface Preparation: Vinyl applied to both exterior and interior of ceramic sake cup
• Sandblasting: Exposed areas sandblasted to create textured surface
• Finishing: Vinyl resist removed to reveal pattern in relief
