Solution Overview

Problem

Existing 3D printing methods for manufacturing multiple components on a printing platform require numerous braking and accelerating operations of the print head, leading to inefficient manufacturing times.

Innovation Solution

The method involves initially forming the outer contour of each component layer, followed by filling the filling regions of multiple components along successive printing paths, reducing the need for frequent changes in direction and acceleration of the print head.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the print head completes one component layer before moving to the next component, then each component layer is manufactured completely, but the number of braking and accelerating operations increases significantly

Engineering Contradiction:
Improvecomponent layer completionVSAvoidmanufacturing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The manufacturing process is segmented into two distinct phases: an outer contour phase where the print head traces the boundary of each component layer, and a filling phase where the print head fills the interior regions. This segmentation allows the print head to maintain continuous motion patterns within each phase, reducing the frequency of braking and accelerating operations between different component layers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outer contour of each component layer is manufactured first before the filling operation begins. This preliminary action establishes the boundary structure in advance, allowing the subsequent filling operation to proceed efficiently without interruption, as the print head can continuously deposit material within the pre-defined contours across multiple components.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If the print head is adjusted along several printing paths for each component layer, then complete coverage is achieved, but the number of direction changes and speed adjustments increases

Engineering Contradiction:
Improveprinting path coverageVSAvoidmanufacturing speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The printing path is divided into two distinct segments: the outer contour path that traces the boundary of each component layer, and the filling paths that traverse the interior regions. By separating these functions into distinct phases, the print head can optimize its motion pattern for each phase, maintaining higher speeds during the filling operation while ensuring complete coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a traditional sequential approach (completing one component before moving to the next) to a multi-dimensional approach where the print head operates across multiple components simultaneously in different spatial regions. The outer contour phase establishes boundaries across all components, and the filling phase utilizes offset printing paths to efficiently cover interior regions, effectively utilizing the spatial arrangement of multiple components to reduce total travel distance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Provided is a method for the additive manufacturing of multiple components by utilizing at least one print head of a 3D printing device, wherein the components are manufactured layer by layer and successively along an axis on a printing platform. It is provided that in a layer plane for each of the components succeeding each other along the axis an outer contour initially is manufactured via the at least one print head, which borders a filling region for the respective component. Subsequently the at least one print head is adjusted along the axis in order to introduce printing material into the filling regions of the multiple components successively along a first printing path, before the print head again is adjusted along the axis in order to introduce printing material into the filling regions of the multiple components successively along a second printing path offset from the first printing path.
