3D Printer Consumable Conveyor with Multi-Channel Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printers, particularly fused deposition 3D printers, have a single-function printing consumable conveyor that cannot adapt to the evolving needs of 3D printing, limiting their functionality and efficiency.
Innovation Solution
A printing consumable conveyor system with multiple feeding channels, a pushing apparatus, and a cutting apparatus that allows for the advancement and retreat of consumables, enabling the automatic switching between different consumables and continuous printing, while also cutting consumables to prevent blockages and jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function printing consumable conveyor is used, then the device structure is simple, but the adaptability to different consumables and printing needs is poor
Solution Approach 1:
The conveyor system is designed with multiple feeding channels (at least two) that can each accommodate different types of consumables, allowing the system to perform multiple functions - conveying different materials, handling different consumable formats, and supporting various printing operations through a single integrated device
Solution Approach 2:
The conveyor system is divided into distinct functional modules including multiple feeding channels, a pushing apparatus with independent control for each channel, and a cutting apparatus, allowing each segment to be optimized for specific tasks while working together as a coordinated system
2Ease of operation
If manual consumable return operations are required, then the device structure is simple, but the manual workload is high
Solution Approach 1:
The pushing apparatus automatically performs consumable return operations by mechanically pushing consumables back into the feeding channels when they are not needed, eliminating the need for manual intervention and allowing the system to manage its own consumable inventory
Solution Approach 2:
The cutting apparatus performs preliminary cutting of consumables to standardized lengths before they are fully consumed, preventing irregular consumption ends from causing blockages or jamming, and ensuring consistent operation throughout the consumable lifecycle
3Productivity
If consumables are not automatically managed, then the device structure is simple, but the productivity is reduced due to frequent manual filling
Solution Approach 1:
The system maintains continuous printing operation by automatically managing consumable supply through multiple feeding channels and a pushing apparatus that ensures consumables are always available, eliminating interruptions for manual refilling and maintaining uninterrupted production
Solution Approach 2:
The cutting apparatus pre-processes consumables by cutting them to appropriate lengths before use, and the pushing apparatus pre-positions consumables in the feeding channels, ensuring that consumables are ready for immediate use without requiring manual intervention during printing operations
4Reliability
If consumable ends are not cut, then the device structure is simple, but blockage and consumable jamming occur
Solution Approach 1:
The cutting apparatus performs preliminary cutting of consumables to standardized lengths and creates clean, regular ends before the consumables are fully used, preventing irregular consumption ends from causing blockages or jamming in the printing head or extruder
Solution Approach 2:
The cutting apparatus transforms the potentially harmful effect of irregular consumable ends (which cause blockages and jamming) into a beneficial outcome by systematically creating uniform, clean ends that prevent these problems, turning a risk into a reliability enhancement

AI summary
A printing consumable conveyor and a 3D printer are provided. The printing consumable conveyor includes a discharging channel, at least two feeding channels, a pushing apparatus, and a cutting apparatus. The at least two feeding channels are each in communication with the discharging channel, and the pushing apparatus is arranged on the feeding channels. The pushing apparatus is configured to drive a consumable in at least one of the feeding channels to advance into the discharging channel, or to drive a consumable in at least one of the feeding channels to retreat. The cutting apparatus is disposed on the discharging channel, and the cutting apparatus is configured to cut the consumable when the pushing apparatus drives the consumable to retreat to a set position. With the arrangement of the pushing apparatus, at least one of at least two consumables can be driven to be discharged or returned.
