Hey guys, we want to print the shoes by Recreus but they are too big to print in one print. How can we split the .stl and then make it possible to join them after printing and still be able to walk in them? Please let us know.

Thanks.

Repetier/slic3r is free and can chop up .stl’s.

Assuming you’re printing with a flexible thermoplastic like tpu/tpe, you will have to weld the parts together with a 3d pen or soldering iron (Definitely recommend practicing this technique before attempting on something that matters!) In my experience, most adhesives/epoxies will not stick and if they do the bond will be rigid.
Good luck.

We were going to use NinjaFlex to print the shoes. You think we should get a 3D Printing pen and connect them?

Thanks.

Depends on the shape/thickness of the parts. I would have a 3d pen (most can do flexible material if you go real slow) and a soldering iron with a flat blade tip (adjustable would be ideal). Honestly this is less of a technical skill and more of an “art”. I’m not an artist so it took some practice and frustration before I got any decent results.
Here’s a good tip though, when practicing, worry about getting a strong bond first instead of how it looks. Once you figure out what it takes to bond the parts you can worry about how to get there as neatly as possible. If you do the opposite it can be frustrating.

I have attached an image of what we a trying to print. Do you think if we used a 3D Printing pen the bond would be strong enough to walk in as if it was one print?

Thanks.

It would be the ONLY way to bond the parts strong enough. If done correctly it would be the strongest part of the shoe.

Would this pen work? Is this all we would need + the fillament?

No idea. My pen is no longer in production and has modifications anyway. “I would have a 3d pen (most can do flexible material if you go real slow) and a soldering iron with a flat blade tip (adjustable would be ideal).”

Hey JMO, Makers Muse made a video a little while back on how to do this–https://www.youtube.com/watch?v=afLolx2OEKE.

hope this helps.

Thanks for the video. We are able to split the files but we are having trouble merging them back together after printing.

Thanks.
