Solution Approach 1:

The patent performs preliminary measurement and calculation of corrected parameters before the next printing run. By pre-calculating the optimal parameter adjustments based on previous deviations, the system minimizes downtime during printer setup while ensuring precision is maintained in subsequent prints.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The automated computational approach replaces time-consuming mechanical adjustments with rapid software-based parameter recalculation. This substitution dramatically reduces the time required to correct precision issues, thereby maintaining productivity while improving dimensional accuracy.

Solution Approach 1:

The patent implements a self-service system where the computer automatically measures deviations, calculates corrected parameters, and adjusts printing settings without human intervention. This automation eliminates manual adjustment time, improving productivity. The system manages its own complexity through integrated software that handles measurement data processing and parameter optimization autonomously.

Inventive Principle:

Solution Approach 1:

The patent replaces repeated manual measurement and mechanical adjustment cycles with a single automated computational process. The computer system efficiently processes measurement data and calculates parameter corrections algorithmically, significantly reducing the time required compared to iterative manual adjustments while maintaining precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system makes targeted parameter changes based on specific measured deviations rather than performing comprehensive re-adjustments. By identifying and correcting only the necessary parameters, the system maintains manufacturing precision while minimizing the time spent on measurements and adjustments.

Inventive Principle:

AI summary

Methods for influencing components or assemblies in a 3D printer provide for automatic adjustment or modified actuation of components or assemblies in the 3D printer. Control data with parameters, by means of which the production of a 3D structure in a 3D printer is controlled, is generated from input data. Once the 3D structure is produced and measured, a comparison is carried out between the specified input data measurements and the data of the actual measurements, and differences are ascertained. In the event that the differences exceed a specified tolerance threshold, at least one parameter of the control data is modified.
