PRU-220Declared input

Declared cavity has no selected exit path

Additive manufacturing

Scope and limits

Capped analytic passages and classified void components prove only geometric reachability from explicitly selected internal points; no powder-flow or evacuation certification.

Materialise — Stainless Steel SS316L Design Guidelines

Source scope
Explicit Materialise metal LPBF, SS316L grade assertion and compatible stainless family; selected full cylindrical voids.
Implementation in Prufi
Minimum hole diameter 2mm, declared hollow-part powder exit 3mm; selected exit must be a connected through-bore with two planar host faces. Simple diameter screen only; complex cavities may need multiple/larger openings (7mm preferred). Connection to an internal powder cavity, full powder evacuation, sealing and unsupported internal roofs are not assessed. The 2mm ordinary-hole screen does not classify blind/through status. PRU220 checks explicit cavity-point reachability through positively recognized complete passages by exact capping and valid Boolean void components; undeclared outlets and unresolved topology remain unassessed. No powder-evacuation certification.
