Current 3D printing technologies for forming volume bodies, particularly in the furniture industry, face challenges in cost-effectiveness and industrial applicability, with existing methods often relying on expensive synthetic resins and lacking efficient material recycling and processing systems.
Innovation Solution
A device and method that utilize a storage and suction system for processing wood materials, including wood foam, dust, and flour, with energy-activated binders and additives, and incorporate a coating and finishing unit for post-processing, enabling the formation of solid structures with enhanced properties through layer-by-layer application and machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wood materials (dust, flour, foam) are used instead of synthetic resins for 3D printing, then cost-effectiveness and environmental friendliness are improved, but material handling and processing complexity increases due to electrostatic charges and adhesion issues
Solution Approach 1:
A coating unit applies a coating material to the wood particles before deposition. This coating material acts as an intermediary that reduces electrostatic charges and improves adhesion between wood particles and the build platform, enabling effective processing of wood-based materials without excessive complexity
Solution Approach 2:
The system changes physical parameters of the wood materials by applying coatings that modify surface properties, reducing electrostatic charges and improving flow characteristics. This allows natural materials to be processed effectively in the 3D printing system
2Productivity
If a storage and suction system is implemented for wood materials, then material recycling and processing efficiency are improved, but device complexity increases
Solution Approach 1:
The storage unit and suction device are integrated into a unified system where waste material is suctioned directly back to the storage unit for reuse. This merging of functions creates an efficient closed-loop system that improves productivity while managing complexity through functional integration
Solution Approach 2:
The system recovers waste wood material through the suction device and returns it to the storage unit for reuse. This recovery mechanism improves material utilization and productivity by minimizing waste and reducing the need for continuous material replenishment
3Manufacturing precision
If coating and finishing units are added for post-processing, then surface quality and adhesion are improved, but manufacturing time and process complexity increase
Solution Approach 1:
The coating unit applies coating material to particles before they are deposited in the 3D printing process. This preliminary coating action ensures proper adhesion and surface quality from the outset, reducing or eliminating the need for separate post-processing steps and saving manufacturing time
