Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In three-dimensional shaping apparatuses, high adhesion between the shaping material and the shaping stage can lead to deformation or breakage of the shaping object during separation.
Innovation Solution
A three-dimensional shaping apparatus with a temperature adjustment portion on the shaping stage that heats or cools the cured shaping object to facilitate separation, using a control portion to manage the temperature and relative position between the discharge portion and the shaping stage, and optionally incorporating hole or groove features on the stage to enhance fixation and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adhesion between shaping material and shaping stage is increased to ensure fixation during shaping, then shaping precision is improved, but separation becomes difficult causing deformation or breakage
Solution Approach 1:
The patent changes the temperature parameter of the shaping stage to control adhesion. During shaping, the stage is heated to a first temperature to increase adhesion and ensure precision. After shaping, the stage is cooled to a second temperature to decrease adhesion and facilitate easy separation without deformation or breakage.
Solution Approach 2:
The patent applies periodic temperature adjustment to the shaping stage - heating during the shaping process to ensure fixation and precision, then cooling after shaping to enable easy separation. This periodic change in thermal state resolves the contradiction between needing strong adhesion during shaping and weak adhesion for separation.
2Stability of the object's composition
If adhesion between shaping material and shaping stage is increased to prevent deformation during shaping, then shape stability is improved, but separation force required increases causing breakage
Solution Approach 1:
The patent uses temperature parameter changes to control the adhesion force between the shaping material and stage. During shaping, elevated temperature ensures adequate adhesion for shape stability. After shaping, cooling reduces adhesion force, enabling separation with minimal force to prevent breakage.
Solution Approach 2:
The patent makes the adhesion characteristic dynamic by adjusting temperature throughout the process. The system transitions from a high-adhesion state during shaping to a low-adhesion state after shaping, allowing the same interface to provide different mechanical properties at different times.

AI summary
A three-dimensional shaping apparatus includes a discharge portion discharging a shaping material, a shaping stage on which the shaping material discharged from the discharge portion is stacked, a temperature adjustment portion provided in the shaping stage to adjust a temperature of the shaping stage, and a control portion. The control portion stacks the shaping material on the shaping stage to shape and cure a three-dimensional shaping object while changing a relative position between the discharge portion and the shaping stage, and then, heats or cools a portion of the cured three-dimensional shaping object in contact with the shaping stage by controlling the temperature adjustment portion to adjust the temperature of the shaping stage.
