  • 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.




  • I may agree in a DIY setting, but for a business it’s a sunken cost fallacy. I’ve owned 2 businesses where productive equipment were integral. Replacing machinery where there is a substantial improvement does make absolute business sense. Also, if you allow a machine to wear out you are shooting yourself in the foot. It’s much better to unload them in the second hand market, and renew. I haven’t owned a print farm, but I’m certain that amortization is fairly quick.


  • The industrial ones may be tough, but the one in the video looks janky and the abundance of printed parts does not inspire confidence in its longevity. Also, it is an addon to an MMU, making the whole multi color set up closer to $500, and limited to bowden, which precludes flexibles. Once a tool has been swapped it must be heated to the proper temp for the filament.

    I’m not intimately knowledgeable with subtractive CNC, but I own and have used a lot a hand router, so I’m familiar with the business end of the things. Reliability is not going to be the same with a dry tool or toolhead, than with an oozy nozzle.

    The system is for bedslingers only, which are inferior to cartesian or CoreXY cube printers.

    The INDX is way more capable, simpler (thus likely more reliable) made by Bondtech, which has a proven reliability and performance record.

    The only scenario where I see this being equal or superior to a toolhead changer is, well, none.

    Wild guess here:

    Maybe your hotend thermistor is failing, but not dead, cutting out intermittently, which could cause the hot end temperature to be fluctuating, thus alternatively under or over extruding.

    To see if your filament is humid, raise your Z, and with a magnifying glass look closely at the extruded stream while you extrude. If wet it will be uneven and/or have bubbles.
