Chocolate is better.
Sure, it can't be used to stick stuff together(well, not permanently... ), but it can buy you forgiveness, and even peace and quiet to tinker with your hobbies.
Hey I just used some of that to fix the carb bowl on my motorcycle. $5 for the epoxy that would have otherwise cost me several hundred for a stupid cheap piece of cast aluminum.
We used some stuff similar at a job I worked at. It was identical in appearance, just more fluid; Master-Cast. We'd pour it in shapes and mill it into molds on a three axis CNC... Nice stuff.
Erco you may be on to something . I saw some 30 Sec Epoxy and I had a idea . Heck FULL bond in a hour . that is fast 1500PSI .
If you could mix it the right way and control the flow and a X Y Z table you know it might work !!
You better have some work lined up if you want to use one of those mixing nozzles. Once you start using one, you get to use it until you stop -- then throw it away. Seems they end up filled with cured epoxy...
More seriously, I have seen (don't remember where) someone doing "architectural" printing at large scale with a mix of what is basically fast-setting epoxy based concrete. It's not cost effective if you use pure plastic, though, because epoxy is hella expensive. Just look at the price of JB-Weld and figure how much you'd need to print something worthy of its strength, such as a pickup truck.
Also, the fast setting version JB QUICK isn't nearly as strong as JB WELD. This seems tobe a universal trait of epoxies; the fast ones aren't very strong (and get VERY HOT CURING) and the strong ones take minutes to set up and a day or more to properly cure.
I have often looked at a fiber-glass chop gun in a crude CNC/Router set-up to print out parts.

This would be a great thread on the Builders forum.

P.S. The MEKP hardener is the probably the worst stuff in the universe.

HA! I love it. I didn't know they were making a new one
