Transport Container Segmentation for Additive Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing layer building methods for additive fabrication face inefficiencies in handling and cooling of objects, particularly due to complex mechanisms for exchanging and cooling replaceable receptacles, which hinder mass production and increase system size and handling complexity.
Innovation Solution
A transport container integrated as a part of the process chamber, allowing for independent handling and automated exchange, eliminating the need for complex receptacle handling and enabling operation at varying pressures, with a built-in drive system for vertical displacement and thermal insulation for easier handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a replaceable receptacle is used for cooling objects outside the sintering machine, then productivity is improved by reducing downtime, but device complexity increases due to complex compensation, centering, clamping, and pivoting mechanisms
Solution Approach 1:
The build chamber is divided into a fixed first section and a movable second section (transport container). The transport container can be segregated from the first section and handled independently, allowing simple removal and insertion without complex mechanisms. This segmentation enables the cooling function to be separated from the build chamber while maintaining simple structural design.
Solution Approach 2:
The cooling function is extracted from the build chamber by using the transport container as a separate cooling unit. The transport container can be removed from the first section and used for cooling objects outside the sintering machine, eliminating the need for complex in-chamber cooling mechanisms while improving productivity.
2Ease of operation
If manual or sliding carriage methods are used for receptacle replacement, then ease of operation is reduced, but device complexity increases due to required compensation and centering mechanisms
Solution Approach 1:
The transport container is designed as a self-contained unit with integrated platform and receptacle. This segmentation allows the entire assembly to be handled as one simple component that can be easily inserted and removed from the build chamber without requiring complex compensation or centering mechanisms.
Solution Approach 2:
The transport container is designed to be self-sufficient with integrated functions for platform support, object cooling, and handling. The container can be independently handled and positioned without requiring external compensation or centering mechanisms, simplifying the overall system operation.
3Productivity
If the transport container is segregated and handled independently, then productivity is improved through faster changeover, but device complexity increases due to connection and disengagement requirements
Solution Approach 1:
The drive system for vertical platform displacement is integrated into the transport container as a self-contained unit. This segmentation eliminates the need for complex connection and disengagement mechanisms between the receptacle and drive system, as the entire assembly moves together as one unit.
Solution Approach 2:
The transport container merges multiple functions into a single integrated unit: the receptacle for holding the platform, the drive system for vertical displacement, and the cooling capability. This combination simplifies handling and eliminates the need for separate connection mechanisms for each function.

AI summary
A transport container for use in a device for producing a three-dimensional object of selective solidification of a build-up material deposited in layers, in which the device has a process chamber closed during operation, where the three-dimensional object is produced in layers. The transport container has a container, in which a height-adjustable platform is arranged, on which the three-dimensional object is produced in layers. The process chamber has first and second sections in which the second section can be separated from the first section and operated in a separate state independently from the device and also can be connected to the first section to produce an operating state of the device.
