Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing three-dimensional printed parts from a build platen are cumbersome, time-consuming, and risk damaging the part or the platen, lacking efficiency and automation.
Innovation Solution
A method and printer system that uses inductive heating and gravity to release the part by rotating the platen to an angle where gravity assists in part removal, combined with inductive heating to melt adhesives, allowing for automated and efficient part detachment without damaging the part or platen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods (heating, impacting, scraping, freezing) are used to remove parts, then part removal can be achieved, but the process becomes cumbersome, time-consuming, and risks damaging the part or platen
Solution Approach 1:
The patent replaces manual mechanical removal methods (scraping, impacting) with an automated thermal field system. An inductive heater generates electromagnetic induction heating to melt adhesive bonds, and a rotated platen uses gravity to guide the part off automatically, eliminating manual mechanical intervention and significantly reducing removal time.
Solution Approach 2:
The patent changes the temperature parameter by applying inductive heating to the platen surface, which melts the adhesive material and enables automatic part release. This thermal parameter change transforms the removal process from manual mechanical force to automated thermal-assisted gravity-driven separation.
2Extent of automation
If manual removal methods are used, then part detachment can be achieved, but automation is limited and manufacturing efficiency is reduced
Solution Approach 1:
The system enables self-service part removal where the platen itself, through rotation and inductive heating, automatically detaches the part without external manual intervention. The gravity force combined with thermal melting creates a self-executing removal process that integrates into the manufacturing cycle, significantly improving automation extent and productivity.
3Productivity
If forceful removal methods (impacting, scraping) are applied, then part removal can be achieved, but the risk of damaging the part or platen increases
Solution Approach 1:
The patent utilizes phase transition of the adhesive material from solid to liquid through inductive heating. By melting the adhesive bond, the part can be gently released without forceful mechanical contact, eliminating damage risks while maintaining rapid removal speed through automated gravity-driven detachment.

AI summary
A method of manufacturing a three-dimensional object facilitates removal of the three-dimensional object from the platen on which the object was formed. The method includes rotating the platen from a horizontally level position to a position at an angle to the level position to enable gravity to urge the three-dimensional object away from the platen and inductively heating the platen to melt support material at the boundary of the object and the platen to release the three-dimensional object from the platen.
