1-Butene Copolymer Base Plate for 3D Printing Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing technologies lack effective base plate materials for extrusion-based 3D printing, particularly for polyolefin-based materials, as existing solutions do not provide adequate adhesion and easy removal of printed objects.
Innovation Solution
A base plate with a top layer comprising 1-butene based copolymer containing 0 to 50 wt% of ethylene, propylene, or alpha olefins, which ensures stable adhesion and easy removal of printed objects during and after the printing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional base plate materials (heated glass plate with vinylic glue) are used for ABS printing, then good adhesion is achieved, but the plate is not suitable for polyolefin-based materials and requires complex preparation
Solution Approach 1:
The invention changes the chemical composition parameter of the base plate by using 1-butene based copolymer instead of conventional glass plate with vinylic glue. This material substitution enables compatibility with polyolefin-based materials while maintaining adhesion capabilities, eliminating the need for complex preparation steps
Solution Approach 2:
The base plate comprises a composite structure with a top layer of 1-butene based copolymer containing specific comonomers (ethylene, propylene, or alpha olefins) in controlled amounts. This composite material design provides both adhesion for diverse materials and ease of operation
2Reliability
If strong adhesion is achieved during printing, then printing stability is improved, but object removal becomes difficult
Solution Approach 1:
The 1-butene based copolymer's chemical composition parameters are specifically controlled (comonomer content, molecular weight distribution) to achieve optimal adhesion strength that balances printing stability with easy removal capability. The material provides sufficient grip during printing but allows clean release afterward
Solution Approach 2:
The base plate material itself provides both the adhesion function during printing and the release function afterward through its inherent material properties, eliminating the need for additional adhesives or complex removal procedures
