    Hey everyone!

    So I stumbled upon something potentially very cool from a supplier of mine.
    I was looking at printing the casting patterns and he mentioned using Machinable Wax's filament used in a loss-wax method of casting metal.

    In my line of work, this is very interesting to me, but was wondering if anyone else had tired the filament.
    I ordered myself a sample and will test it out in the printer.

    and apparently there are a number of foundries that will use the prints you make in their casting process. seems to be pretty cheap over the traditional methods.

    Not to date myself but back in our senior year at LMU (2000) we had a 3d printer that printed in wax only. We then used the wax prints to make investment castings over in the art department since they had all the equipment to turn a wax part into metal.

    Please let us know if this works well. If so that would be awesome!!

    Thanks

    Sounds cool, though I think PLA is also good for lost investment casting as it burns out clean

    That has been my experience. Lost PLA casting is cool.

    This makes me happy! I'd love to start casting gas powered RC motors.

    Anyone try this yet? If not I'll be the guinea pig at the end of the month.

    I have done lost PLA casting, I have not tried this specific filament.
    Any PLA will work for the method I used. This filament would likely be a little easier to use.

    You'll have to modify the firmware to allow extrusion at 140-150C as the firmware currently locks extrusion to being at a minimum of 170C.

    Actually, some firmware versions have 190C as minimum. Good point though.

    Thanks for the info on the firmware. I ordered a sample of Machinable Wax filament and that was ONE OF my problems. Before installing the firmware, no wax was coming out of the extruder. Now that I have installed the firmware, I am getting a small amount of wax from the extruder during calibration and for the outline that is printed before the printer actually starts to work on the actual object, but after that I am not getting any wax out of the extruder.If anybody has used this filament and has any relavent experience to share, I would appreciate any feedback or suggestions.

    Thanks,

    Timbo

    Mark, what is the process you use, do you heat the mold to burn out the PLA or just hot enough to melt it out?

    I usually have top ports and pouring in the metal (gently, slowly) will flash all of the PLA away. *POOF* gone. Smoke goes out the ports ... At least with the metals we have tried (brass/aluminium)
