Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional modeling apparatuses face challenges in forming clean outlines of objects due to differences in fluid material distribution, leading to rounded outlines on the upper surface.
Innovation Solution
A three-dimensional modeling apparatus with an ejection portion and control portion that ejects fluid material onto the outline section of a laminated body, allowing for correction processes to align the outline height with the body section height, using techniques like raster and vector scans for precise material deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fluid material is ejected in liquid droplet form to model a three-dimensional object, then the object can be formed through repeated lamination of cross-section bodies, but the outline section becomes low and rounded due to insufficient material flow compared to body sections
Solution Approach 1:
The control portion performs a correction process by ejecting fluid material onto the outline section of the laminated body before finalization. This preliminary action compensates for the anticipated material deficiency in outline sections, ensuring uniform height and clean outlines in the final object.
Solution Approach 2:
The correction process targets specifically the outline section of the laminated body, applying additional fluid material only where needed. This localized quality adjustment ensures that outline sections receive sufficient material to match the height of body sections, while leaving other areas unchanged.
2Manufacturing precision
If the correction process ejects fluid material onto the outline section to form clean outlines, then the outline height uniformity is improved, but the modeling time increases due to additional processing steps
Solution Approach 1:
The control portion merges the correction process with the cross-section body formation process by simultaneously executing both operations. This combination allows the ejection portion to form cross-section bodies while also performing correction ejections onto the outline section, thereby maintaining high modeling speed while achieving clean outlines.
Solution Approach 2:
The ejection portion continuously ejects fluid material along the shape of the target correction location during the correction process. This continuous action eliminates interruptions and maintains steady progress, ensuring high-speed correction without compromising outline precision.

AI summary
A three-dimensional modeling apparatus includes an ejection portion capable of ejecting a fluid material, which is a material of an object, and a control portion that forms a laminated body in which one layer or more of cross-section bodies are laminated by executing one or more repetitions of a cross-section body formation process, which forms a cross-section body equivalent to one layer of the object by controlling the ejection portion and ejecting the fluid material. The control portion executes a correction process that ejects the fluid material onto a target correction location, which is at least a portion of an outline section of an upper surface of the laminated body.
