3D Printed Slip Casting Mold Larger than the Print Bed

- How can we create 3D printed slip casting molds larger than the print bed? We need to split them apart! Here I build on ways to attach 3d printed parts together to be able to pour plaster slip casting molds. The outer shell is printed in several parts and assembled together using threaded inserts and foam gasket to create a strong plaster tight seal. That is attached to an inner mold (although I had a few bugs in my software that need to be fixed!) Pour in plaster and then disassemble. Once the screws are removed the outer mold basically falls off and the inner mold can easily be removed by making very cold. Best of all, all of the 3D models needed for this are automatically generated from a simple 2d sketch using my software.

Amazing engineering. There is a lot of work. Glad to see progress with scalability not limited to 3d printer bed. Keep it up. There is definitely lot of opportunity on how we make molds in a much easier way.
The new mold is a thing of beauty! So satisfying when the outer mold comes apart so easily!
Very impressive trouble shooting with absolute minimisation of the finished mold. Well done and very interesting.
One feature of the cad software I use frequently is the ability to 3D print threaded holes. I do tend to use M5 to M8 bolts, but I am able to avoid having to deal with threaded inserts. Saves a little time and money. Of course,self-tapping screws would work too.
I'm very interested in the mold generating software you are developing . . . if/ when you decide to make it available to try and/ or purchase let me know. You could have have something that could be very popular with potters who want to get into slip casting but (like me) have had difficulty finding molds for waht the want to produce. many of the commercial plaster mold makers are out of business or have a very limiter selection. I'd be willing to pay for a software solution designed for "us".
Nice work. Gives me some great ideas
Excellent 👍
I get that the exterior doesn't need to be pretty, so the rough texture and flashing isn't a big deal. But it seems to me you would want something better for the internal displaced object, yeah? PLA printers might give you better results. They're getting super cheap and their build trays are getting up there also. I've got an older Anycubic Mono X and absolutely love it.
BEAUTIFULY DONE
The plaster molds look great. I'd add handle wells to the sides to make lifting easier.
Thanks
Love this series, this is so clever and something I would definitely want to try, thanks for sharing your experience. I wondered why you made a smaller bowl out of the black plastic, if the smaller one is the ideal size then after the clay shrinks it'll be even smaller no? edit: Or did you say the software scales it up to account for it?
great job.. I been looking into making molds this way as well. BTW Where do you get that foam tape i would always use the mold soap You can mix whit vinegar and water 50/50 to remove the soap.
Kent do you use waterproof foil tap or regular duct foil tape?
I've "upgraded" two of my priners to 0.6mm jewelled nozzles (one diamond, the other ruby). Print times are significantly reduced, and decent resolution is possible I find very functional mold prints at 0.20mm resolution, and for exterior pieces (not part of the slip cast piece) work well at 0.4mm resolution. The last printer is still a 0.4mm nozzle, though also a jewelled part for longevity (I hope). So I am able to get down to 0.07mm resolution without issue; just takes forever to print...
Clay question:
Hi Kent are these stl files available to purchase anywhere, I'm on the waiting list for the software
