Solution Overview
Problem
Existing digital manufacturing systems for 3D model creation are limited by the availability of consumable materials with a wide range of optical and compositional characteristics, restricting the variety of 3D models that can be built due to high production costs of multiple materials.
Innovation Solution
A compounding system that blends stock materials to form customized consumable materials with desired optical and compositional characteristics, allowing for a wide variety of qualities to be achieved from a limited number of stock materials, reducing production costs and expanding the range of possible 3D model characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manufacturers provide a wide selection of consumable materials with different optical and compositional characteristics, then the variety of 3D models that can be built increases, but the production costs increase significantly
Solution Approach 1:
The system changes the optical and compositional parameters of consumable materials by blending different stock materials in varying proportions. The compounding system allows dynamic adjustment of material characteristics (color, transparency, flexibility, strength) by controlling the ratio and combination of base materials, enabling a wide range of 3D model properties without manufacturing each material variant separately
Solution Approach 2:
The invention creates composite consumable materials by combining multiple stock materials (different polymers, colors, or compositional variants) in controlled proportions. The compounding system extrudes blended mixtures of stock materials to form new material properties, allowing the system to achieve diverse material characteristics from a limited set of base components, thereby reducing the need to manufacture and store numerous separate material types
2Adaptability or versatility
If manufacturers pre-manufacture and store multiple types of consumable materials, then material selection flexibility increases, but inventory complexity and storage costs increase
Solution Approach 1:
The compounding system serves multiple material functions using a single multi-functional device. Instead of requiring separate storage and dispensing systems for each material type, the compounding system can blend different stock materials to create various consumable material variants on-demand. This universal system replaces complex inventory management with a simpler stock material storage approach, where the same compounding device produces different material properties through controlled blending ratios
3Ease of manufacture
If a limited number of stock materials are used, then production costs decrease, but the range of achievable 3D model characteristics is restricted
Solution Approach 1:
The system achieves diverse material characteristics by changing the blending parameters of stock materials. By adjusting the proportion, ratio, and combination of base materials in the compounding process, the system generates a wide spectrum of optical properties (color, transparency, gloss) and compositional properties (flexibility, strength, rigidity) from a limited set of stock materials, effectively expanding material versatility without increasing the base material count
