Solution Overview
Problem
Existing plasticizing devices require multiple units to supply molten material to multiple nozzles, complicating the configuration of three-dimensional shaping devices due to the need for a single communication hole at the center of the barrel.
Innovation Solution
A plasticizing device with a rotating unit, barrel, and heater, featuring multiple communication holes and groove parts at the barrel's bottom surface, allowing molten material to be supplied to multiple nozzles without increasing device complexity, by using a single plasticizing unit with multiple communication holes and groove parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single communication hole is provided at the center of the barrel, then the device configuration is simple, but the molten material cannot be supplied to multiple nozzles efficiently
Solution Approach 1:
The single communication hole is segmented into multiple communication holes (first communication hole, second communication hole, etc.) at the bottom surface of the barrel. Each communication hole is coupled with corresponding groove parts that distribute the molten material to different nozzles, enabling one plasticizing device to serve multiple nozzles simultaneously
Solution Approach 2:
The barrel bottom surface is designed with multiple communication holes and groove parts that can supply molten material to multiple nozzles. This multi-functional design allows a single plasticizing device to replace multiple plasticizing devices, each originally required for one nozzle, thereby reducing overall device complexity while maintaining versatility
2Reliability
If multiple plasticizing devices are provided for multiple nozzles, then each nozzle receives adequate molten material, but the device configuration becomes complicated
Solution Approach 1:
Multiple communication holes and their associated groove parts are merged into a single integrated barrel structure. This consolidation allows one plasticizing device to perform the function of multiple separate devices, maintaining reliable material supply to all nozzles while reducing the total number of plasticizing devices required
3Productivity
If multiple communication holes are formed at the barrel bottom surface, then molten material can be supplied to multiple nozzles from a single device, but the barrel structure becomes more complex
Solution Approach 1:
The material distribution function is segmented into multiple communication holes and associated groove parts. Each groove part is specifically designed to guide molten material from its corresponding communication hole to the intended nozzle, ensuring efficient distribution while maintaining a systematic and organized barrel structure
Solution Approach 2:
The communication holes and groove parts are arranged in specific spatial patterns on the barrel bottom surface. This spatial arrangement optimizes the distribution of molten material to multiple nozzles in different directions, achieving high productivity through effective use of three-dimensional space rather than simply increasing structural complexity

AI summary
A plasticizing device includes: a drive motor; a rotating unit driven to rotate about a rotation axis by the drive motor and having an end surface perpendicular to the rotation axis; a barrel having a bottom surface facing the end surface of the rotating unit, and a heater; and a material supply unit supplying the material between the rotating unit and the barrel. At the bottom surface of the barrel, a first communication hole through which the molten material flows out, a first groove part coupled to the first communication hole, a second communication hole through which the molten material flows out, and a second groove part coupled to the second communication hole are formed.
