Solution Overview
Problem
Current additive manufacturing methods are limited to producing one product at a time, leading to increased manufacturing time and costs, and lack flexibility in producing geometrically complex and large products with varying properties.
Innovation Solution
A method and device for controlling process parameters in a 3D printing device to partition a virtual printing volume into zones with different parameters, allowing multiple 3D products with varying properties to be manufactured in a single batch, enabling flexible production of products with different resolutions, densities, and materials within the same batch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple products are manufactured in one batch, then productivity is improved, but device complexity increases due to need for parameter partitioning and control
Solution Approach 1:
The printing volume is divided into multiple zones with different process parameters. Each zone can have independent control of process parameters such as layer thickness, printing speed, and material properties, allowing simultaneous production of multiple products with different requirements in a single batch
Solution Approach 2:
The system dynamically adjusts process parameters based on the zone in which the print head is currently operating. The control system modifies parameters in real-time according to the spatial position and assigned zone, enabling flexible multi-parameter control without requiring multiple fixed printing systems
2Adaptability or versatility
If different process parameters are applied to different products, then adaptability is improved, but manufacturing precision may worsen due to parameter variations
Solution Approach 1:
Different regions of the printing volume are assigned different process parameters tailored to the specific requirements of products in those regions. This allows each product to receive optimized parameters for its specific geometry and material requirements while maintaining overall batch production
Solution Approach 2:
The system changes process parameters such as layer thickness, printing speed, and temperature based on the zone and product being manufactured. This enables adaptation to different product requirements while the control system maintains precision through coordinated parameter adjustment across all active zones
3Loss of time
If continuous products with no distinct layers are printed, then manufacturing time is reduced, but the ability to manufacture geometrically complex products worsens
Solution Approach 1:
The system uses continuous printing where possible to reduce manufacturing time, but selectively introduces layer boundaries and pause-resume operations only where geometric complexity requires it. This partial application of continuous printing maintains speed benefits while preserving geometric capability

AI summary
The present disclosure relates to a method for controlling the manufacturing of one or more 3D products in one batch by additive manufacturing using a layer-by-layer technique using a 3D printing device, and a 3D printing device. The 3D printing device comprises a control unit adapted to govern a plurality of process parameters, the batch having a 3D printing volume. The method comprises the steps of; providing a virtual 3D printing volume (40) representative of the 3D printing volume (PV) of the batch; partitioning the virtual 3D printing volume (40) into at least a first and a second zone (50a-50h) and; assigning the first zone (50a-50h) with a first process parameter, and the second zone (50b-50h) with a second process parameters, whereby the first process parameter is different with respect to the second process parameter.
