  • Dry and then store in sealed container with silica gel. Silica will maintain dryness, but will not dry filament by itself.

    Also, containers must have a seal of some kind. Regular plastic tubs will let some moisture in. For a few days or a couple of weeks that’ll be fine, but over a month they’ll let moisture in. Get vacuum bags.

    There are pretty cheap reusable vacuum bags that use a little pump. I use a cheap kitchen vacuum machine, and regular food storage vacuum bags.




  • I live in a dry climate, and thought drying PETG was unnecessary. After a lot of frustration, I made a (very good) redneck dryer, and my printing life became much better. PETG really likes water, and printing humid PETG is a source of major frustration.

    Also, don’t dry filaments in ovens, microwaves, or other food use things. A lot of idiots on YouTube recommend that, and it’s obvious that you don’t want to cook foods in ovens that have been coated in unknown VOCs.





  • I really like elegoo rpetg. It really likes moisture, though. Not a problem for me with my redneck dryer, though.

    I’ll be making a video with my setup soon.

    I had a bunch of rolls of plain petg, and dumped them on a second hand market. Never looking back.

    Also, Sunlu PLA+ 2.0. Great PLA.

    I want to try Polymaker HT-PLA-GF. High temp resistance (150°C) right off the printer, more if annealed, and glass fiber. Should be a great replacement for many engineering filaments, but printable on vanilla printers without enclosure/filters.


  • Epoxy can be a bit of a crap shoot with plastics. It works wonderfully for some, a not at all for others. I have worked a lot with epoxy and plastics are always a “try somewhere else in the part” thing. Also, if there is grease on the part" forget it. Even with epoxy especially formulated for plastics.

    If all you want is to use the epoxy as a filler, it may work.

    I have searched aliexpress, and there are kits for around 17€. I don’t know what the shipping and customs are where you live.









  • Is that compatible with other brands? I believe most MMUs are only compatible with their own printers. That’s another advantage of INDX, and other toolchangers I’m sure are in the pipeline. I’m going to be installing an INDX in my heavily modded Ender 5 Plus, and if I ever decide to sell it, or retire it, I know I’ll probably be able to carry it over to another printer.
