3D Printer Cover Segmentation for Automated Series Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printers with temperature-controllable assembly spaces hinder automated series production by requiring manual intervention for removing finished objects, complicating the transition to producing the next object.
Innovation Solution
A thermally insulated assembly space with a two-part cover that can be decoupled and moved independently of the print head, allowing automated removal and replacement of objects without manual intervention, facilitated by releasable coupling means and a conveying unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the assembly space is enclosed by thermal insulation on all sides, then temperature control and thermal insulation are improved, but automated removal of finished objects becomes difficult
Solution Approach 1:
The cover is divided into two parts: a first part that moves with the print head and a second part that can be independently positioned at a parking position. This segmentation allows the assembly space to remain thermally insulated during printing while enabling automated removal of finished objects through the opening created by the separable cover parts.
2Stability of the object's composition
If the cover is fixed to maintain thermal insulation, then temperature stability is improved, but ease of operation for series production deteriorates
Solution Approach 1:
The cover transitions from a static, fixed structure to a dynamic system where the first part moves with the print head during printing and the second part can be independently positioned. This dynamic configuration maintains thermal insulation during printing while enabling easy operation for series production through automated object removal.
3Extent of automation
If a hinged or sliding door configuration is used for the side wall, then automated object removal is improved, but device complexity increases
Solution Approach 1:
The first part of the cover serves multiple functions: it moves with the print head during printing to maintain thermal insulation, and it can be separated from the second part to enable automated object removal. This multi-functionality avoids the need for separate hinged or sliding door mechanisms, reducing device complexity while maintaining automation capability.

Function Achieved in This Case
Enables automated series production of 3D printed objects by simplifying the removal and preparation of new base plates, reducing setup costs and enhancing production efficiency.
Implementation Method 1
a temperature-controllable, thermally insulated assembly space for an object to be produced
Implementation Method 2
liquid or pasty material can, for example, be applied at an increased temperature from a print head that can be moved relative to the object to be produced, to the object to be produced and can solidify there by cooling
Implementation Method 3
a powdered or pasty material may, for example, also be connected by means of local action of heat within the assembly space, for example by means of a laser beam, to the object to be produced
Implementation Method 4
a pasty or liquid material may, for example, also be cured on the object to be produced by activating or curing with UV light within the assembly space
