    Re: RAG-79 Aqua GM 1/144

    You think you'd be putting this up for sale on Shapeways when it's all said and done?

    I really want to buy one of those printers, they've gone down in price ALOT, but damn the UV resin is expensive. Close to 90 a bottle.

    There is finishing work even after shapeways.
    I'll probably just make conversion kits and sell on ebay.

    for speed of producing its good, with a big caviat,
    the build trays are $65 and have a short life span, really short. especially if a print fails...and they do. Once the resin hits them , the clock is ticking.
    Resin is 165 a bottle. From formlabs
    The resin is sticky and super messy.
    you go through boxes of vinyl gloves, and gallons of isoprpyl alcohol.
    Big footprint in any setting. The printer size is nice, but your cleaning station is twice that size.
    Ans I'm really tasking my machine printing these parts...compared to the beautiful stuff from Shapeways.

    I spend my workday around 3D printers making my prototypes. Trying to do it in my off time would absorb every minute.
    I know instant gratification is important, but let somebody else do the work if you can..
    spend your time designing good cad files. (its less sticky)

    Don't worry some of us are watching. I'm just sitting in the corner quietly watching. But now I have a few new questions. What silicone rubber do you use? I have been looking at a ton of them and now I have seen so many I have put myself in a sea of too much information so my brain has vapor lock and can't decide. LOL
    Second, Your cast just curious, why did you make the mold so big for just the two parts? I have a few parts I need to make casts for and I didn't think that it would have to be a very big mold, but seeing yours made me wonder is there a reason for the large mold? or is that just a "the way I like it" thing.

    Lastly why did you have to make resin casts of the parts? They looked good to go from the shapeways parts. Do they not sand out well or something?

    Other than those questions, this thing is looking really good. You are really selling the uses of a 3D printer for customizing builds.


    To error is human, to forgive is divine, Luckily I'm neither of these things!

    Re: RAG-79 Aqua GM 1/144

    I'm curious. Did you use a vacuum chamber or pressure pot when you cast the parts or did you just poor the resin into the mold?

    Did you buy the pressure pot or did you make it?

    Re: RAG-79 Aqua GM 1/144

    The Pressure pot is just a 2.5 gal paint pot that has a gauge and outlet valve. I run it up to 50psi. more than enough.
    Your molds still need to be made to not trap bubbles.
    I wouldn't make a pressure pot, unless you are an engineer, know what you are doing and have the right equipment to do it...that could be seriously dangerous. and more expensive in the long run.

    As for silicone, I use a tin base GI-1000 from Silicones inc.
    Tin base silicone is not finicky about set up inhibitions like a platinum base rubber.
    I think smooth on has a similar product

    The mold is a bit over sized for those parts, yes.
    I like to inject the resin so it fills from the bottom up so I need to make a channel for that.
    The mold is rubber banded together with two 1/8 MDF plates to keep it square and under even pressure.

    I could be more economical with the supplies, but I'm trying to get this done for a show on the 4th.

    And last, I could use the Shapeways parts, but they still needed clean up and I figured I might be able to sell a couple of resin conversion kits after this one is done.

    I'm really looking forward to finishing now!
