Solution Overview

Problem

Existing additive manufacturing techniques face challenges in increasing manufacturing quality and efficiency, particularly in the production of functional, real-world objects, with limitations in object removal and post-processing processes.

Innovation Solution

The use of microsupport arrays in additive manufacturing, comprising a base, rail, and body portions, where the body portion includes a deflection point designed to break upon object removal, allowing for easier object detachment and integration of microsupport fragments into the object.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional support structures are used in additive manufacturing, then objects can be supported during printing, but object removal becomes difficult and time-consuming

Engineering Contradiction:

Improveobject removal efficiencyVSAvoidpost-processing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The support structure is divided into multiple microsupports (e.g., 9-36 microsupports) distributed across the build platform, allowing parallel removal through multiple deflection points rather than removing a single large support structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The microsupports are designed with pre-positioned deflection points that are configured to break at specific locations during object removal, enabling automatic fracture at the weakest point without requiring additional cutting or breaking operations

Inventive Principle:

Principle #10Preliminary action

2Strength

If support structures are designed to be strong for structural integrity, then they provide adequate support during printing, but they are difficult to remove without damaging the object

Engineering Contradiction:

Improvesupport structure strengthVSAvoidobject removal ease

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The microsupports have non-uniform cross-sectional geometry with defined deflection points that create localized weak regions. The body portion connects the base and rail portions with varying thickness, concentrating stress at specific deflection points while maintaining overall structural strength during printing

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The deflection points are pre-designed at specific locations along the body portion where the cross-section is intentionally reduced or geometrically modified to create predetermined fracture zones that will break cleanly during object removal

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If microsupport arrays are used to improve print accuracy, then manufacturing precision increases, but device complexity increases

Engineering Contradiction:

Improveprint accuracyVSAvoidmicrosupport array complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The microsupport array design serves multiple functions simultaneously: providing structural support during printing, enabling precise object positioning through the rail portion, and facilitating easy object removal through predetermined deflection points. The same microsupport structure accomplishes support, positioning, and release functions

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The microsupport combines several functional elements into a single integrated structure: the base portion anchors to the build platform, the body portion provides structural connection with embedded deflection points, and the rail portion attaches to the object, merging support, positioning, and release mechanisms into one component

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A microsupport array for additive manufacturing includes a plurality of microsupports on a build platform. Each microsupport includes a base portion on the build platform, a rail portion configured to attach to an additively manufactured object, and a body portion connecting the base portion and the rail portion, optionally wherein the body portion comprises a deflection point. A part of the body portion is configured to break upon removal of the additively manufactured object from the build platform at the deflection point, when present.
