MDF isn't easy to get the sort of finish you require, as mentioned it first needs to be sealed, then rubbed down ect, very labour intensive. i have used a product called eposeal, it's a two part epoxy and very thin but when dry it can be rubbed down and should be sealed(used it to seal some Iroko windows that had water penetration)

Now that's the question?
I dont have a CNC so have to do my woodworking using router/spindle the advantage with CNC is you can take off very small cuts using high feed rates and i believe this vastly reduces breakout. If you don't want to make them out of acrylic i think i would try some quality beech ply, but that's only a guess.

You can get a good finish on MDF, if you seal it with epoxy, and sand until glass smooth.Gerry

Commercial finishing processes rarely involve much manual work, if you use a self levelling primer after sealing you will have to sand rough areas after sealing but you won't need them perfectly smooth, experimentation will determine how smooth you need to go to achieve what you need ;-)
I've achieved good finishes on wood sealed with an alcohol based automotive sealer, U-Pol's version of this is Barcoat, others are available. Snother option if you want to do more sanding is to use a Polyester based spray filler, U-Pol's version of this is Reface, it sands very easily and doesn't clog paper like hand mixed polyester fillers,

You think that's too expensive? You're not a Model Engineer are you? :D
