Standard MJF PA12 parts are commonly grey or grey-black, with dyed black a popular finishing route. Other colours and white-material routes require confirmation with the supplier and material grade.

Dyeing does not make a dark base white. Bright or light colours need a suitable base material or an agreed coating route. Confirm appearance using a representative sample.

Yes, where the material and geometry allow. The order matters: for example, smoothing may precede painting or coating. Identify the required result and protected surfaces so the complete route can be reviewed.

Send the 3D CAD model, any 2D drawing and the parts list. Include the material, quantities, target appearance, colour reference, roughness requirements, masked areas and critical dimensions.

It can. Material removal, coating buildup or thermal processing may affect dimensions and edges. State whether tolerances apply before or after finishing and identify mating faces, bores and threads.

Request a representative sample during quotation when colour, texture or gloss is critical. The sample scope, cost and timing are agreed for the project.

No. Compatibility depends on the exact grade, geometry, surface access and intended use. The quotation confirms which operations are included and any sample approval required.
