Compare Internal Structure Concepts
Understand how six TPMS and lattice structures were arranged within the same demonstrator.
Review Manufacturing Feasibility
See the recorded LPBF results for thin walls, surface roughness and build density.
Define the Next Validation Stage
Identify which thermal, hydraulic and product-level tests still need to be completed.
Prepare a More Complete Project Brief
Use the validation framework to define operating conditions, inspection requirements and acceptance criteria.
Support Beyond the Case Study
Addireen supports 316L heat exchanger and thermal component projects from initial manufacturability review through printing, post-processing and inspection coordination.
Application-Oriented Engineering Review
Review geometry, wall thickness, internal-channel accessibility, interfaces and project requirements before manufacturing.
316L LPBF Manufacturing
Develop manufacturing plans for complex internal structures and integrated fluid components.
Post-Processing Coordination
Plan support removal, machining, surface treatment and internal cleaning according to project requirements.
Inspection Planning
Define dimensional, density, surface and internal-channel inspection requirements for the manufactured sample.
From Demonstrator to Product Qualification
The case study documents the demonstrator stage and identifies the additional validation required before product use.
Completed in This Study
The study records six structures in one 316L demonstrator together with qualitative flow observations and LPBF build results.
Functional Validation Required
Further validation should cover thermal performance, pressure drop, leak tightness, powder removal and particle cleanliness.
Defined for Each Application
Each application requires project-specific review of material compatibility, service life, critical interfaces and acceptance criteria.
