I wanted to try new slic3r multi-extruder features on my Replicator 1 using stock

I wanted to try new slic3r multi-extruder features on my Replicator 1 using stock firmware 7, got it working by writing a post processing script: https://gist.github.com/tbuser/5074361

Then I used it to print my gearbox test using HIPS, currently soaking in a bottle of limonene: http://www.flickr.com/photos/tbuser/8522775217/in/photostream/

Still waiting for my HIPS. How does the it print? The similarity to ABS suggests that it would perform a lot better than PVA…

It pretty much seems to behave exactly like ABS and ABS adheres to HIPS MUCH better than PLA sticks to PVA. I’ve only printed 2 things with it so far, but it’s looking really good.

Now someone needs to figure out how to make it dissolve faster in limonene.

Based on the chemical composition, that’s exactly what I expected.

Obvious things to try to make it dissolve faster: agitation, aeration, heating, and obtaining more concentrated limonene.

Since ABS also contains styrene, does the limonene not change the ABS’ properties? I’d think the surfaces would get a lot softer since the other two components of ABS, butadiene and acrylonitrile, are of rubber-like consistency.

About 12 hours later, it’s mostly dissolved. Still some deep inside that are preventing the gears from turning, so back into the limonene it goes… http://www.flickr.com/photos/tbuser/8525137155/in/photostream/

So far ABS, PLA, and LAYWOO-D3 seems unaffected by limonene. Also, HIPS dissolves in acetone.

I wonder if it would take less time to dissolve if you used a magnetic stirplate or this DIY one - http://www.thingiverse.com/thing:42445 to keep the limonene flowing.
