Deposition Data Collection for 3D Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D printing methods struggle to accurately collect 3D modeling data for objects with complex features or irregular shapes, such as food or handicrafts, leading to poor quality products.
Innovation Solution
A deposition data collection apparatus that includes a printing unit with an extruder and a printer head capable of moving along arbitrary deposition paths, and a scanning unit that chronologically collects material deposition data, including information on both the inner and outer structures of the target object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If 3D modeling data is generated by scanning the outer shape of a pre-manufactured target object, then the manufacturing process is simple, but accurate 3D modeling data cannot be collected for objects with complex features or irregular shapes
Solution Approach 1:
Instead of scanning a finished object to infer its construction, the patent inverts the approach by directly recording the deposition process to generate 3D modeling data. The deposition data collection apparatus captures the actual material deposition process, creating accurate 3D models without requiring reverse engineering from a finished object.
Solution Approach 2:
The patent creates a direct copy of the deposition process through digital recording. The sensing module captures the actual material deposition path and parameters, creating an accurate digital replica of the object's construction process, which serves as the 3D modeling data for reproducing the object.
2Ease of operation
If conventional scanning methods are used to generate 3D modeling data, then the process is straightforward, but inner structure information of the target object is lost
Solution Approach 1:
The patent performs preliminary recording of the deposition process during object creation. By capturing the deposition path, layer thickness, and material distribution during the actual construction process, the system preserves inner structure information before the object is completed, eliminating the need for post-hoc scanning or reverse engineering.
3Manufacturing precision
If manual 3D modeling is performed for irregular objects, then accurate representation is possible, but the time and labor required increase significantly
Solution Approach 1:
The deposition data collection apparatus enables the object's creation process to automatically generate its own 3D modeling data. As the object is being deposited or manufactured, the sensing module simultaneously records the deposition parameters and path, allowing the object to essentially model itself without requiring separate manual intervention or post-processing.

AI summary
Disclosed is a deposition data collection apparatus including: a printing unit including: an extruder for ejecting a material supplied from an external material source; and a printer head for moving the extruder in a predetermined direction such that the material ejected from the extruder are sequentially deposited along an arbitrary deposition path on an XYZ coordinate system to form a target three-dimensional object; and a scanning unit including: a sensing module for sensing movement of at least one of the extruder and the printer head; and a data collection module for chronologically collecting material deposition data including the arbitrary deposition path, based on the movement sensed by the sensing module.
