ADDITIVE

MJF

MJF is a powder-bed polymer process reviewed around packing, wall behavior, feature clearance and finishing.

ENGINEERING DOSSIER

Balance powder removal, fusion behavior, dimensional intent and post-processing for MJF

Powder removal and feature access

Identify internal spaces, fine channels and interfaces that need reliable cleaning access.

Repeat-part orientation

Review packing and orientation against surfaces and relationships that must remain consistent.

Material, color and use

Connect polymer choice and any dye or color intent to the actual functional and appearance requirement.

Inspection after finishing

Check critical interfaces after cleaning and finishing, not only immediately after the build.

MANUFACTURING ROUTE

Route logic for MJF

Identify internal spaces, fine channels and interfaces that need reliable cleaning access. Connect polymer choice and any dye or color intent to the actual functional and appearance requirement.

Review packing and orientation against surfaces and relationships that must remain consistent. Best input: CAD, quantity and finish intent.

DECISION CONTROLS

Release controls specific to MJF

Best input

CAD, quantity and finish intent

Key risk

Packing, cleaning and visible consistency

Release evidence

Post-finish interfaces and repeatability

DECISION QUESTIONS

MJF route and release questions

What must be defined before reviewing MJF?

Identify internal spaces, fine channels and interfaces that need reliable cleaning access. Review packing and orientation against surfaces and relationships that must remain consistent.

Which interfaces need project-specific confirmation?

Connect polymer choice and any dye or color intent to the actual functional and appearance requirement. Escalate Packing, cleaning and visible consistency and any geometry, access, material or interface requirement that the drawing does not resolve.

What should accompany release?

Check critical interfaces after cleaning and finishing, not only immediately after the build. Post-finish interfaces and repeatability

PROJECT BRIEF

MJF project brief and release checklist

Use these page-specific checks to turn the MJF route into reviewable CAD, drawing and inspection inputs.

Geometry and route input — Powder removal and feature access

Identify internal spaces, fine channels and interfaces that need reliable cleaning access. Include the relevant CAD orientation, interfaces and quantity in the review brief.

Release evidence — Repeat-part orientation

Review packing and orientation against surfaces and relationships that must remain consistent. Name the drawing dimensions and inspection evidence required at release.

RFQ handoff — Material, color and use

Connect polymer choice and any dye or color intent to the actual functional and appearance requirement. Upload controlled CAD/drawing inputs and state the unresolved route decision.
