    Salt anneal pla

    I had this idea spent a bunch of time and money proofing the idea in SAND a while ago and got 1 successful anneal that retained dimensional spec in sand. Using salt however seems more efficient and cleaner cause sand is dirty. I think there is however, a trick to having it retain dimensional spec, even buring it in salt, and that is to compress the entire package put it under spring compression during the anneal.

    I might mess around with this in the summer.

    Theoretically you can anneal over PETG safe temps i.e. petg is good up to 80c, you can anneal to over 100c. I guess you could also just anneal the PETG then. Anyways it's got potential but it's a shoddy and annoying process, and can fail dimension ally if the process isn't good. Seems interesting tho.

      How many psi did that vessel take? Way cool stuff here! Im just learning a little about printing at work, I had to send this video to one of the guys who knows their stuff. They are also very interested. I wish I had a printer, Id start messing with this to give ya more data.

        Aight I bought like 5 cartons of table salt and I'm going to give this a shot eventually - when lockdowns in Canada lift and I can finally go to the dollarama and actually check-out GLASSWARE LOL WTF THEY WON'T SELL ME GLASSWARE yo I need to store my noodles bro it's essential.

        In the meanwhile I'll run some smaller tests, perhaps on pressure vessels and see if it will blow if I hook it up directly to CO2 lmao. CONTENT

          Okay got a small set of samples in the oven will report in 2-3 hours the result.

          Cheers It's taking forever to cool down I figure another hour and I'll just quench it in water if it's still warm. I believe this should react the same as metal, slow cool down eases stress and reduces brittleness, while instant quench theoretically would explode my glass vessel... but would make a very very hard part that will shatter rather than crunch, but may be stronger, will try both.

          Edit : Test 1 failed to reach proper internal temperature. Will redo- tomorrow on the BBQ.
