Is it possible thie element to be produced whit CNC router machine from plastic ?

Greetings to all of you.

Since I need to make just few elements like this and plastic injection molding will be very expensive is it possible this shape to be produced whit CNC?

Thanks in advance,

You need a 3d CAM program (like DeskProto) and some ball-nose endmills. If you use DeskProto, try the 2-side wizard. It won't be particularly economical to mill them out individually, if you're selling them, but as a prototype it should work fine. You could also make a 2-piece silicone rubber mold and cast them in urethane, if you want to do a limited production run.

Yes, that could absolutely be produced on a 3D mill/router. Another option would be rapid prototyping.

Thanks you really for the info.
Casting is not an options in this case I need many kind of different objects similar to this on the picture but 1 - 5 pieces max. Probably the best options is rapid prototyping. I found this printer: http://www.printin3d.com/3d-printers...nal-3d-printer at a reasonable price which probably will do the work.

You do need to be aware of the limitations of the printer, and the resolution you get. I have no idea what you are wanting the parts for, but the printer will leave ridges on the the surface. I suggest you use a service to have a few parts made on the machine you plan to purchase to insure that the surface finish is sufficient to meet your needs. You can get rapid prototyping machines from $8000 to over $300000, and there is obviously a difference in the output of the different machines. Again, the low end machine may well meet your needs, but only you can answer that question!
