Too Much Poop, Post Processing, Printing Threads and More!

This Episodes Questions:

Hey guys,
First of all, thanks so much for the podcast. I really enjoy the banter and the in-depth analysis you guys offer. With MMU's being so popular and with Bambu Lab's intro into the market with the AMS, I was immediately intrigued at the ability to hit a button and generate a multi-color print. However, in looking into it, I noticed the waste it was producing and just can't bring myself to pull the trigger on one and contribute to that waste pile. I'm curious if you guys had any thoughts on how you would design an "AMS-like" unit that would be able to turn out a multi-color print all while producing minimal to no waste. Or is just something that is unavoidable?
Thanks again for the great content!

I have read a little bit online about various methods of post-processing of plastic prints to improve strength, toughness and reduce voids. I understand there is a way use a type of salt that is packed tightly around a print to maintain it's shape and then the print is annealed at high heat. Have guys tried this and if so what was your experience? To me it sounds like a great idea, but like most things the devil is likely in the details.

I'd like to include some threads on some printed parts so I can connect them using bolts. When I try to print my parts, the threads are not clean enough to use. I design them .01 proud to leave room for the bolt. I'm printing them with the bolt going through the Z-axis, but the results aren't great. Any suggestions or reference to sources to get this figured out?
