Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printing technologies face challenges in maintaining the stability and accuracy of printing food materials due to interference from agitation or exclusion of materials during the printing process, and the inability to supply materials at optimal temperatures corresponding to their characteristics.
Innovation Solution
A 3D printing apparatus with a material accommodating unit, a printing unit, and a transfer unit, featuring separate spatial arrangements to prevent material interference, and temperature adjusting components to ensure the printing material is supplied and sprayed at temperatures suitable for the food material, including an agitating portion, temperature adjusting portions for the accommodating and transfer units, and a thermoelectric module for the nozzle head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the material accommodating unit and printing unit are disposed close to each other for compact structure, then device complexity is reduced, but material agitation or exclusion interferes with the printing process, worsening printing stability
Solution Approach 1:
The printing apparatus is divided into distinct functional units: a material accommodating unit for storing and preparing printing material, a transfer unit for transporting material, and a printing unit for deposition. This segmentation allows each unit to operate independently, preventing material agitation in the accommodating unit from interfering with the printing process while maintaining a compact overall structure.
2Device complexity
If temperature control is not implemented for the transfer pipe, then device complexity is reduced, but printing material cannot be supplied at optimal temperature, worsening printing accuracy
Solution Approach 1:
A temperature control system is implemented for the transfer pipe to maintain the printing material at an optimal temperature during transport. This parameter control ensures that temperature-sensitive materials (such as chocolate or other food materials) retain their desired viscosity and flow characteristics, enabling accurate deposition in the printing unit while the system remains integrated and compact.
3Device complexity
If printing material is not supplied at optimal temperature, then device complexity is reduced, but printing accuracy deteriorates due to material property changes
Solution Approach 1:
The system incorporates temperature control mechanisms in both the material accommodating unit and the transfer pipe to maintain the printing material at its optimal temperature throughout the printing process. This ensures that materials with specific temperature requirements (such as food materials) maintain their intended rheological properties, enabling precise printing while keeping the overall device structure integrated and manageable.
