Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional printer systems lack a polymeric material that balances flexibility and shape retention, making it difficult to print complex shapes effectively, as existing materials like ABS are prone to warping and PLA is brittle.
Innovation Solution
A thermoplastic composition with a matrix polymer and dispersed microinclusion and nanoinclusion additives, forming a porous network that enhances flexibility and strength, allowing for the creation of complex shapes without warping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ABS polymer is used as build material, then flexibility and machinability are improved, but warping occurs when placed into contact with the print surface
Solution Approach 1:
The patent uses a composite material system consisting of PLA as the base polymer combined with ABS accents or blends. This composite approach allows the material to inherit the shape retention and warping resistance of PLA while incorporating the flexibility and machinability benefits of ABS, thereby resolving the contradiction between ease of operation and manufacturing precision
Solution Approach 2:
The patent modifies the thermal and mechanical parameters of the base material by incorporating ABS components. This changes the glass transition temperature, melt flow characteristics, and cooling rates, allowing the material to maintain shape fidelity like PLA while achieving the flexibility and reduced warping associated with ABS
2Reliability
If PLA polymer is used as build material, then renewability and resistance to warping are improved, but brittleness and lack of flexibility worsen
Solution Approach 1:
The patent creates a composite material system where PLA serves as the continuous matrix phase and ABS is incorporated as the dispersed accent phase. This composite structure allows the material to maintain the renewable nature and warping resistance of PLA while the ABS accents provide enhanced flexibility and impact strength, resolving the contradiction between reliability and strength
Solution Approach 2:
The patent applies local quality by distributing ABS accents throughout the PLA matrix in a non-uniform manner. The ABS components are concentrated in specific regions or at critical stress points, providing localized flexibility and impact resistance where needed while maintaining the overall shape retention and renewable characteristics of the PLA base material

Implementation Method 1
a thermoplastic composition containing a continuous phase that includes a matrix polymer
Implementation Method 2
extruding a flowable build material. In such systems, the build material is typically extruded through an extrusion tip and deposited as a sequence of layers
Implementation Method 3
The extruded build material fuses to previously deposited build material and solidifies upon a drop in temperature
