Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support structures for dental objects in additive manufacturing offer limited stability and require excessive material usage.
Innovation Solution
A method involving columnar support structures reinforced with lattice structures, which can be arranged laterally, around, or integrated with the support structures, using triangular, quadrangular, pentagonal, or hexagonal lattice configurations, to enhance stability while minimizing material consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pillar support structures are used, then the support structure can be manufactured with low material usage, but the stability is insufficient
Solution Approach 1:
The patent combines two different support structure types (pillars and lattices) into a composite support system. The pillar structures provide vertical support with minimal material, while the lattice structures provide lateral stability and reinforcement. This composite approach resolves the contradiction by integrating the advantages of both structures: low material usage from pillars and high stability from lattices.
2Stability of the object's composition
If lattice support structures are used, then the stability is improved, but the material input increases significantly
Solution Approach 1:
The patent divides the support structure into two functional segments: pillar structures that provide vertical support and lattice structures that provide lateral reinforcement. By segmenting the support function, the design achieves high stability through the lattice portion without requiring the entire support structure to be made of material-intensive lattice, thus reducing overall material input while maintaining stability.
Solution Approach 2:
The lattice structures are applied locally rather than uniformly throughout the entire support structure. The patent positions lattice reinforcement specifically where lateral stability is needed, while other areas use simpler pillar structures. This local application of lattice structures provides necessary stability without the excessive material input that would result from universal lattice construction.
3Ease of manufacture
If traditional support structures are used in additive manufacturing, then the manufacturing process can be completed, but the structural reinforcement requires excessive material
Solution Approach 1:
The patent applies lattice structures partially rather than excessively. Instead of creating complete lattice structures throughout the entire support system, the invention uses lattices only in specific regions where additional reinforcement is needed. This partial application provides sufficient structural reinforcement for successful manufacturing while avoiding the excessive material consumption that would occur with comprehensive lattice construction.
