Solution Overview

Problem

Current 3D printing systems face inefficiencies and increased complexity when scaling up production, leading to idle time and potential errors due to the lack of effective workflow management in systems with multiple 3D printers, build units, and material processing units.

Innovation Solution

A 3D printing management system that utilizes a processor-based management system to obtain and analyze status data from various elements, determine schedules, and generate control data to optimize the workflow, ensuring efficient operation and reducing errors by coordinating the use of multiple 3D printers, build units, and material processing units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple 3D printers, build units, and material processing units are added to increase production capacity, then productivity increases, but device complexity and workflow management difficulty increase

Engineering Contradiction:
Improveproduction capacityVSAvoidworkflow management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

A management system acts as an intermediary between multiple 3D printers, build units, and material processing units. This central coordinator receives status data from all components, determines optimal schedules, and generates control data to coordinate operations, thereby managing the increased complexity while maintaining high productivity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The management system dynamically adjusts schedules and resource allocation based on real-time status data from various components. It continuously monitors system state and reoptimizes workflows to adapt to changing conditions, maintaining efficiency as the system scales

Inventive Principle:
Principle #15Dynamics

2Productivity

If manual coordination of multiple build units and printers is used, then device complexity is lower, but idle time increases and productivity decreases

Engineering Contradiction:
Improveidle time reductionVSAvoidworkflow automation level
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system enables automated self-coordination of resources. The management system automatically monitors status data, determines schedules, and generates control data without human intervention, allowing the system to self-manage workflows and eliminate idle time through automated decision-making

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The management system continuously receives status data from printers, build units, and material processing units, using this feedback to dynamically adjust schedules and resource allocation. This closed-loop control ensures optimal utilization of resources and minimizes idle time

Inventive Principle:
Principle #23Feedback

3Productivity

If centralized management system is implemented to coordinate all units, then productivity and resource utilization improve, but device complexity and initial setup complexity increase

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidsystem integration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The management system is designed as a universal platform that can coordinate multiple types of components (3D printers, build units, material processing units) through standardized interfaces and protocols. This multi-functionality allows it to handle diverse operations while maintaining a unified control architecture

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system architecture is segmented into independent functional modules: status data acquisition, schedule determination, control data generation, and communication interfaces. This modular design reduces integration complexity by allowing each component to be developed and maintained independently while working together through standardized protocols

Inventive Principle:
Principle #1Segmentation

AI summary

Management system to control a 3D printing system that includes at least one 3D printer, at least one build unit in which 3D objects can be generated by the 3D printer, and at least one material processing unit in which processing operations can be performed on the build unit. The management system comprises a processor to obtain status data from at least some of the elements of the 3D printing system, to obtain data relating to a print job to be printed, to determine, from the obtained data, a schedule of operations to be performed by elements of the 3D printing system and to generate control data to allow enforcement of the determined schedule.
