PROCESS SELECTION & VALIDATION
BAM will compare additive manufacturing with conventional alternatives against the application, quantity and required performance.
Our proposed pilot would investigate large-format polymer printing for reusable mould tooling. Equipment access, casting compatibility, finish, release behaviour and tool life need testing.
A printed mould is not automatically cheaper, faster or suitable for reuse.
CNC machining, fabricated tooling and established mould-making routes form the comparison. The pilot should record where an existing method is the better choice.
Compare the complete design-to-casting workflow, including finishing and rejects.
Concrete printing is a separate process and a longer-term research area. Structural use requires appropriate engineering, material qualification, testing and a project-specific approval route.
Printing walls does not establish delivery of a complete compliant home.
A REPEATABLE TEST
EXTERNAL RESEARCH / CHECKED 13 OCTOBER 2026
NIST identifies continuing testing and durability challenges for additively constructed structures. HUD’s field research examines integration of printed walls with conventional building components. These references inform our caution; they are not evidence of BAM performance or Nigerian approval.
Independent test results, supplier quotations and applicable Nigerian requirements will be needed for the actual pilot. No supplier affiliation is implied.
