Solution Overview
Problem
The existing building apparatuses face issues with generating unintended conspicuous streaks when processing slice data and forming material layers in parallel, leading to deteriorated object quality due to excessive waiting time and incomplete slice data generation.
Innovation Solution
A building apparatus with a control unit that manages the timing of forming material layers, ensuring the interlayer time does not exceed a predetermined upper limit by generating a certain number of slice data pieces before starting the layer formation, and using UV curable ink with a UV light source for enhanced adhesiveness between layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If slice data generation and layer formation operations are performed in parallel to reduce waiting time, then building time is reduced, but unintended conspicuous streaks are generated in the object
Solution Approach 1:
The control unit generates a predetermined number of slice data pieces in advance before starting the layer formation operation. This preliminary generation of slice data ensures that when layer formation begins, the necessary data is already prepared, allowing parallel processing to reduce waiting time while maintaining data completeness to prevent streaks.
Solution Approach 2:
The control unit monitors the generation status of slice data and dynamically adjusts the layer formation start timing based on feedback from the data generation process. This feedback mechanism ensures that layer formation only begins when sufficient slice data is available, preventing streaks while maximizing parallel processing efficiency.
2Productivity
If layer formation starts immediately after first piece of slice data is generated to shorten waiting time, then building time is reduced, but incomplete slice data causes unintended streaks
Solution Approach 1:
Instead of starting layer formation immediately after the first slice data piece is generated, the control unit performs a preliminary action by generating a predetermined number of slice data pieces first. This ensures data completeness before initiating the layer formation process, preventing streaks while still enabling efficient parallel processing.
Solution Approach 2:
The control unit generates more slice data pieces than strictly minimum required (excessive action) to ensure that when layer formation starts, the data is sufficiently complete to prevent streaks. This partial over-generation of data ensures quality while maintaining high productivity through parallel processing.

Data Source
AI summary
To provide a building system for building an object, including a building apparatus that ejects a material of the object, a data generation unit, and a control unit. The data generation unit generates ejection position designating data based on input data indicating the object in a format different from that of the ejection position designating data. During a time when the data generation unit performs an operation of generating the ejection position designating data, the control unit causes a head to form a plurality of material layers constituting at least a part of the object, and sets a layer forming start timing for starting to form the material layers so that the interlayer time does not exceed an upper limit time set in advance. Hence, appropriately building a high quality object.
