Multi Material Rattle Trap

This is a Multi Material version of my other Rattle Trap and is meant to be printed in one piece using multiple colors of filament. (for when you get tired of painted lures.)

Designs like these are meant for printers that can print in multiple colors with either more than one extruder or with a add on device like this Mosaic Palette 2 Pro. This device mounts to the side of my printer and 4 different colors are feed into it and it can then splice them together at the right points and feed the output into a single extruder.

I figured I’d test the new Palette 2 out by trying something useful so I started out by chopping up my original rattle trap design. This was the original design but each color of the new design needed to be made into its own separate part in order for the Palette to know how much filament to make for each color.

These are what the separate parts look like.  I did group certain colors (like all the black bits) into a single part so the STL’s would be easier to assemble.

This is what the assembled parts would look like before being sliced.

I’m using the Canvas Software that Mosaic provides. It’s in BETA form right now but it’s pretty easy to work with.

I had a few problems getting the Palette setup but finally got it to work as intended. Here is the first test print of the new rattle trap. It didn’t come out too bad but as you can see I still need to work on the slicer settings as this print has some under-extruding issues.   The big block at the top is the waste block… this multi color printing process does create a lot of waste but it’s necessary to bleed the old color out of the printers extruder before the next one starts and it does it at every layer. (multiple times if there are multiple colors per layer.)

I didn’t use supports and I could have designed the cut ups better so the insides are pretty sloppy but once assembled it won’t even matter.

I had a few issues with the colors bleeding or not transitioning enough but it’s still came out pretty good for the first print of this design.

Even with the under extrusion I decided to still assemble the halves into a finished print. (I don’t think the fish will judge the print quality.)

I also printed one in a silver pattern too but I haven’t assembled this one yet. I had some bleeding issues with the red but it actually looks pretty cool in person. I tried this one with supports and this slicers supports leave something to be desired… they are hell to remove.

Even though they are not painted I still have to seal them with epoxy.  This one is all set to hit the water but it has to wait until next season as everything is starting to freeze over in New England.

7/5/19 – Possibly the worlds first fish caught on a multicolor 3D Printed lure and it’s gotta be a Bluegill. 🙄
