Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional additive manufacturing apparatuses are designed for maximum manufacturing size, leading to inefficiencies when manufacturing small three-dimensional objects, as they require a large amount of material powder and involve significant cleaning efforts during material replacement.
Innovation Solution
The introduction of a build region limitation unit that includes a movable unit fixed to the build table and a non-movable unit placed on the base frame, allowing for the formation of a smaller build region within the additive manufacturing apparatus, thereby reducing material usage and simplifying cleaning processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the additive manufacturing apparatus is designed for maximum manufacturing size, then it can manufacture large three-dimensional objects, but it requires a large amount of material powder and increases cleaning effort when manufacturing small objects
Solution Approach 1:
The build region is segmented into a first build region and a second build region that is smaller and located within the first build region. The build region limitation unit can be switched between a first configuration (covering the entire first build region) and a second configuration (covering only the second build region), allowing the apparatus to adapt to different manufacturing sizes and reduce material powder consumption when manufacturing small objects.
Solution Approach 2:
The build region limitation unit is configured to be movable between a first position where it covers the entire first build region and a second position where it covers only the second build region. This dynamic reconfiguration allows the apparatus to optimize the build region size according to the manufacturing needs, reducing material powder consumption for small objects while maintaining the capability to manufacture large objects.

3Loss of time
If a dedicated material reuse unit is prepared for each material powder used in experiments, then cleaning time and effort during material replacement is reduced, but manufacturing costs increase
Solution Approach 1:
The build region limitation unit is designed as a separable component that can be removed from the additive manufacturing apparatus. When material replacement is needed, the build region limitation unit can be taken out, allowing the material reuse unit to be cleaned without requiring separate dedicated units for each material, thus reducing manufacturing costs while still enabling efficient material replacement.
Solution Approach 2:
The build region limitation unit serves multiple functions: it defines the second build region for small object manufacturing, acts as a barrier to prevent material contamination, and can be removed to facilitate cleaning of the material reuse unit. This multi-functionality eliminates the need for dedicated material reuse units for each material, reducing costs while maintaining efficient material replacement capabilities.

AI summary
A build region limitation unit for an additive manufacturing apparatus includes a movable unit fixed to a build table and a non-movable unit placed on a base frame. The movable unit includes a first anti-scattering frame provided to protrude upward. The non-movable unit includes a flat plate that covers a first build region with a portion other than an opening and forms a second build region, and a second anti-scattering frame that is provided to protrude downward at an outer periphery of the opening. The first anti-scattering frame surrounds the second anti-scattering frame with a gap therebetween.
