3D Modeling Heater Control for Uniform Surface Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional modeling devices experience heating unevenness due to the use of heating units that do not uniformly heat the modeling material, leading to inconsistencies in the modeled objects.
Innovation Solution
The device incorporates a first heating unit with a plate-like shape featuring through holes and multiple heater parts, along with a control unit that adjusts the output of these heater parts based on measured distances or temperatures to ensure uniform heating by varying the heating intensity across different regions of the heating surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating unit is used to heat the modeling material, then the material is heated to enable modeling, but heating unevenness occurs leading to inconsistencies in the modeled objects
Solution Approach 1:
The heating unit is divided into multiple heater parts (first heater part, second heater part, etc.) corresponding to different heating regions. Each heater part can be controlled independently to compensate for position-dependent heating variations, thereby achieving uniform temperature distribution across the modeling surface.
Solution Approach 2:
Different heater parts are assigned different outputs based on their respective positions relative to the stage. The control unit adjusts the output of each heater part according to the distance between the heating surface and the stage, ensuring that each region receives appropriate heating intensity for uniform overall heating.
2Power
If the heating surface is positioned close to the stage for efficient heating, then heating efficiency is improved, but temperature distribution becomes non-uniform
Solution Approach 1:
The control unit dynamically adjusts the output of each heater part based on real-time measurements of the heating surface position. When the heating surface is close to the stage, the system compensates for the resulting temperature non-uniformity by varying the output of different heater parts, maintaining both efficiency and uniformity.

AI summary
A three-dimensional modeling device includes a first heating unit including a heating surface that heats a plasticized material stacked on a stage, a measurement unit including a first sensor that measures a position of the heating surface, and a control unit. The heating surface includes a first heating region and a second heating region, the first heating unit includes a first heater part and a second heater part, and the control unit executes first processing for setting an output of the first heater part lower than an output of the second heater part when it is determined, based on measurement of a position of the heating surface, that a distance between the first heating region and the stage is a first distance and a distance between the second heating region and the stage is a second distance larger than the first distance.
