Solution Overview
Problem
Existing 3D printing methods struggle to balance printing quality and efficiency due to the varying printing difficulties of two-dimensional slice images, often leading to failures or poor quality when using manufacturer-provided or experiential parameters.
Innovation Solution
A method for 3D printing that calculates a printing difficulty value for each slice image based on cross section information, allowing for adaptive adjustment of printing parameters to match the specific challenges of each slice image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If printing parameters are set strictly to avoid printing failure, then printing quality is improved, but printing time increases
Solution Approach 1:
The patent segments the printing process by dividing slice images into different difficulty categories (first difficulty with single cross-section, second difficulty with multiple cross-sections). Different printing parameters are assigned to different difficulty levels, allowing optimized parameter selection for each category rather than using uniform strict parameters for all slices, thus reducing overall printing time while maintaining quality.
Solution Approach 2:
The patent applies local quality by setting different printing parameters for different slice images based on their specific difficulty characteristics. Instead of using the same parameters for all slices, the system adjusts parameters locally according to each slice's cross-section complexity, ensuring appropriate quality control where needed while allowing faster processing where possible.
2Productivity
If printing parameters are set loosely to reduce printing time, then printing efficiency is improved, but printing quality deteriorates
Solution Approach 1:
The patent segments slice images into difficulty categories and assigns appropriate parameters to each segment. For simple single-cross-section slices, more efficient parameters can be used, while for complex multi-cross-section slices, stricter parameters are applied, thus improving overall efficiency without compromising quality on difficult slices.
Solution Approach 2:
The patent changes printing parameters based on slice difficulty classification. By dynamically adjusting parameters according to the calculated difficulty values and cross-section characteristics, the system optimizes the balance between printing speed and quality for different types of slices, improving overall printing efficiency while maintaining necessary quality standards.
3Ease of operation
If manufacturer-provided printing parameters are used, then ease of operation is improved, but adaptability to different slice difficulties deteriorates
Solution Approach 1:
The patent implements self-service by enabling the printing system to automatically calculate difficulty values for each slice image and select appropriate parameters without requiring manual user analysis. The system autonomously classifies slices into difficulty categories and adjusts parameters accordingly, maintaining ease of operation while significantly improving adaptability to different slice characteristics.
Solution Approach 2:
The patent introduces feedback by calculating difficulty values based on cross-section information and using this feedback to dynamically adjust printing parameters. The system continuously evaluates slice characteristics and adapts parameters based on the calculated difficulty, ensuring appropriate parameter selection for each slice while maintaining automated operation.

AI summary
A method and apparatus for 3D printing, a 3D printer and a computer device are provided. According to the method, a slice image set of a three-dimensional model to be printed is acquired; cross section information of each slice image in the slice image set is determined, and a printing difficulty value of each slice image in the slice image set based on the cross section information is calculated. Printing parameters of each slice image based on the printing difficulty value are determined. A printing operation based on the printing parameters is determined, to print the three-dimensional model based on the printing operation. In the printing process, the printing parameters may be adaptively adjusted along with the changes in the printing difficulty values of the slice images.
