The prototype part in the attached image was created in Rhino, and I can provide a CAD file in almost any format. The part is 1.125" in diameter and 2.54" in length. The concave surfaces of the blades were extruded normal to the core, and then offset by .05" to create solid 3D blades; the convex blade surfaces are therefore not normal to the core. I believe the part can still be milled using 4-axes, but the offset of the convex sides of the blades may make that difficult.

The material can be either aluminum or a plastic that is suitable for prolonged exposure to steam, and the cost should be included in the quote.

The quantity needed is 2, and the timeframe is ASAP.

The RFQ will end at the close of business on 4-9-07.

Thanks.

You could try using a 3d printer service for this. You would get a plastic version with a fair finish but not sure that it would withstand the high temp. Use it to make a mold and then cast. Probably cost you about $35-60 and take about 2 hrs.

I have seen some neat tricks done on these laser printers.

I can do this with metal deposition similar to SLA but with metal. Send me the data in .stp format to ken@teammaroney.com and I'll see if I can quote 2 of these for you. I believe that we could also injection mold this for you out of an engineered resin if you proceed to production with this.

I have to agree with Ken on this one. SLA will be fine. You need to use the right photopolymer. I'll need a STL to give you an exact quote

They are definately doing some magic with rapid protoyping these days. As mentioned new machines are capable of making "ready to use" parts for a lot of applications.

Production - I would consider moulding, die casting or even low numbers can be done with sand casting reasonably (if it is accurate enough).

I am considering maybe $2k to machine you aluminum ones and you will need to supply a SolidWorks, parasolid or step file (before quoting) for me to toss into my CAM and see if thats even feasable.
