Flattening Roller Chrome Plating and Carbon Steel Blade for 3D Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional object shaping devices face issues with excess shaping material adhering to the roller section, leading to undesirable effects like color mixing and material accumulation, which can compromise the accuracy and quality of the shaped object.
Innovation Solution
A three-dimensional object shaping device is designed with a flattening roller coated with chrome plating and a plate-shaped member made of carbon tool steel or resin, along with a blade unit and reservoir, to effectively scrape off excess material from the roller surface, ensuring high durability and scraping performance over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a roller section is used to remove extra shaping material by adhering it to the roller surface, then the layer height control is improved, but the scraped material may re-adhere to the layered surface causing color mixing and quality defects
Solution Approach 1:
The patent extracts the harmful scraped material from the roller surface immediately after removal by introducing a blade that scrapes the adhered material off the roller. This prevents the material from re-adhering to the layered surface, thereby eliminating color mixing while preserving the layer height control benefit.
Solution Approach 2:
The patent introduces a blade as an intermediary element between the roller and the layered surface. The blade acts as a mediator that removes the scraped material from the roller surface without allowing direct contact between the roller and the layered surface, thus preventing re-adhesion.
2Productivity
If a blade is used to scrape off material from the roller, then material removal is improved, but the blade wears down over time reducing scraping performance
Solution Approach 1:
The patent changes the material parameter of the blade from conventional materials to resin material. This parameter change provides wear resistance while maintaining scraping effectiveness, ensuring consistent scraping performance over time without the blade degrading rapidly.
Solution Approach 2:
The patent uses resin material for the blade, which represents a composite or advanced material approach. This material selection combines durability and scraping effectiveness, allowing the blade to maintain its functional properties over extended operational periods.
3Duration of action of stationary object
If chrome plating is applied to the roller surface, then the roller durability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies chrome plating to the roller surface, which is a surface treatment parameter change. This provides enhanced durability and wear resistance to the roller while being a standard industrial process that balances manufacturing complexity with performance benefits.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enhances the ability to remove excess shaping material from the roller surface, preventing re-adhesion and maintaining high scraping performance, thus ensuring accurate and consistent layer formation in three-dimensional object creation.
Implementation Method 1
chrome plating is coated on the surface of the flattening roller
Implementation Method 2
the shaping material that has once been removed must not adhere again onto the layered surface by rotation of the roller body
