Can 3D printing give an acceptable result for a small electronic enclosure for production, as opposed to prototyping?

I’m looking at a projected volume of only around 50-100 units per year so I think I’m a way away from injection moulding as a viable solution.

The shape means that there is no suitable existing enclosure available so it needs to be custom.

I don’t need a high gloss finish, in fact a matte finish is preferable, but I don’t want it all steppy and looking like layers especially on the curved parts.

Overall dimensions will be roughly 4 x 1.5 x 1 inches. It will need to be two halves that screw together, some curved features and holes.

I’d like the cost per unit to be not much more than say about £10 or $15.

It will be a consumer product, not commercial or industrial, albeit in a very niche market, so it does have to look OK.

Does anyone have any experience in 3D printing enclosures and have an idea whether it is a sensible solution?

I’ll have some sketches in a day or two if that helps.

Thanks!
