RE: Procedure to buid a prototype

Date: Tue Jan 11 2000 - 16:48:16 EET


Have a look at <> there in a 57
slide presentation on the process as it relates to investment casting. It
may help! The best books out there relating to the RP industry are
available from the Society of Manufacturing Engineers Fundamentals of
Stereolithography: Rapid Prototyping and Manufacturing by Paul Jacobs would
be one recommendation. I found one book on the Barns and Nobel web site and
when it arrived I found that the authors had plagiarized most of the
material in it. I have since filed a complaint with the publisher and it
has been removed from the B&N site. One of the other books that I consider
to be of value is Marshall Burns, Automated Fabrication (gives you a great
history lesson on the industry). This book is out of print however and you
will have to contact Marshall at Ennex (I hope that is spelled right, I'm
having a terrible mind block this morning).

Any way others out there will certainly be adding to this response.

        Hello List,

            I just have an idea of the constroction process of a Prototype
but I
        have never seen a real Prototype beeing building in a Rapid
            My knowledg about the RP tecnology is from some benchmakers,
        internet sites and here in the rp-ml. The literature in books about
RP is
        very poor in my opinion, because I did a research in amazon books
and I
        just found out only one book that I still didn't buy. I have never
read any
        book about RP...
           I think the procedure to build a prototype with a RP machine
could be:
            1. Desing a threedimensional model in CAD;
            2. Choose the technical parameters desired in the prototype
         accuracy,resolution, speed, surface finish );
            3. Choose the material of the prototype;
            4. Choose the RP technology if more than one is available;
            5. Prepare and simulate the process of construction in CAM;
            6. Convert the file designed in CAD in .stl format and solve
problems in
        the .stl file;
            7. Construct the prototype;
            8. Post process.

        - Does anyone agree with this sequence?
        - What would be wrong ?
        - Could anyone give me an example of the construction of a real
        and all parameters involved (include the RP machine)?

            Thanks in advance,

            Mechanical Engineering Student
