Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deposition heads in three-dimensional printing, used for producing titanium components, face challenges in achieving high material deposition rates while maintaining a satisfactory surface condition, as larger wire diameters are required for increased deposition but result in inferior surface quality.
Innovation Solution
A deposition head design that allows for simultaneous deposition of multiple wires with a guide system and drive mechanism, featuring a pivotable drive roller and friction braking system, ensures consistent wire feed speed and section, improving surface quality and deposition rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wire with large section is used to increase material deposition rate, then productivity is improved, but manufacturing precision deteriorates due to unsatisfactory surface condition
Solution Approach 1:
The invention divides a single large-section wire deposition into multiple smaller wire depositions. The guide system includes a passage hole with multiple passage sections, each accommodating a separate wire. By depositing multiple wires simultaneously (e.g., 2-4 wires), the system achieves the required material deposition rate while maintaining satisfactory surface condition, as each smaller wire contributes to forming the ideal rectangular section of the material layer without the surface quality issues associated with single large-wire deposition.
2Productivity
If multiple wires are deposited simultaneously to improve productivity and surface condition, then manufacturing precision and productivity are improved, but device complexity increases
Solution Approach 1:
The guide system is designed with a passage hole that serves multiple functions: it guides multiple wires simultaneously, maintains their alignment, and controls their positioning relative to the deposition zone. The passage hole with multiple passage sections acts as a universal guiding structure that handles several wires through a single integrated component, reducing the need for separate guiding mechanisms for each wire and thereby managing device complexity while enabling multi-wire deposition.
Solution Approach 2:
The invention merges the guiding functions for multiple wires into a single passage hole structure. Instead of providing separate guide components for each wire, the passage hole integrates multiple passage sections that collectively guide all wires through one unified structure. This merging approach simplifies the overall guide system architecture while maintaining the capability to deposit multiple wires simultaneously with consistent positioning.
3Device complexity
If a single wire is deposited to maintain simple device structure, then device complexity is reduced, but productivity decreases due to lower material deposition rate
Solution Approach 1:
The invention transitions from single-wire deposition to multi-wire deposition by adding the dimension of parallel processing. The passage hole is configured with multiple passage sections arranged in specific spatial configurations (e.g., linear or radial arrangements), enabling simultaneous deposition of multiple wires. This dimensional expansion in the wire feeding architecture allows the system to maintain relatively simple device structure while significantly increasing material deposition rate through parallel wire feeding.
