Solution Overview

Problem

Current 3D printing technologies are limited in throughput due to the need for a single large installation space, which complicates component production, increases costs, and reduces manageability, as they struggle to efficiently handle multiple construction jobs simultaneously without compromising component quality.

Innovation Solution

A 3D printer arrangement with multiple installation spaces allows for simultaneous processing of multiple construction jobs in adjacent spaces, using a shared coater and printing device setup, enabling efficient and cost-effective production without sacrificing component quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single large installation space is used for 3D printing, then component production capacity is increased, but operational complexity increases and manageability decreases

Engineering Contradiction:
Improvecomponent production capacityVSAvoidoperational complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the construction space into multiple separate construction chambers (first construction chamber, second construction chamber, etc.), each capable of independent operation. This segmentation allows the system to handle multiple construction jobs simultaneously while keeping each chamber manageable in size, thus increasing overall productivity without proportionally increasing operational complexity.

Inventive Principle:
Principle #1Segmentation

2Productivity

If a single large construction chamber is used, then throughput is limited, but dividing into multiple chambers increases system complexity

Engineering Contradiction:
ImprovethroughputVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple construction chambers within a single 3D printer system, sharing common components such as the support structure, coating arrangement, and control systems. This merging approach increases throughput by enabling parallel construction jobs while avoiding the full complexity of multiple independent systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coating arrangement and printing device are designed to serve multiple construction chambers universally. The same coating mechanism can apply coating material to different chambers, and the printing device can selectively print on multiple chambers, reducing the need for duplicate specialized equipment and thereby managing system complexity.

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

3Productivity

If multiple construction jobs are processed simultaneously in one large space, then throughput increases, but component quality may be compromised

Engineering Contradiction:
ImprovethroughputVSAvoidcomponent quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

By segmenting the construction space into separate chambers, each chamber maintains controlled environmental conditions and dedicated processing resources, ensuring that component quality standards are met for each construction job even when multiple jobs run simultaneously. This prevents interference between adjacent construction operations that could compromise precision.

Inventive Principle:
Principle #1Segmentation

4Loss of time

If a single build platform is used, then setup time between jobs increases, but multiple platforms increase device complexity

Engineering Contradiction:
Improvesetup time between jobsVSAvoiddevice complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent assigns a dedicated build platform to each construction chamber, allowing simultaneous operation of multiple build jobs on different platforms. This eliminates the need to clear and resetup a single platform between jobs, significantly reducing idle time while the modular chamber design keeps the overall device complexity manageable.

Inventive Principle:
Principle #1Segmentation

AI summary

A 3D printer (100) is described, which is configured to build a three-dimensional component layer by layer by forming superimposed layers of particulate building material and selectively solidifying a portion of each building material layer. The 3D printer (100) is configured to simultaneously build one or more first three-dimensional components in a first build chamber (B1) located within the 3D printer and one or more second three-dimensional components in a second build chamber (B2) located adjacent to the first build chamber (B1) at a horizontal distance from it within the 3D printer (100).
