Alright guys, I know some of you have gotten your Igus Tribo filament. But have any of you actually printed with it? I spent a couple hours trying to print wear samples yesterday on a MakerBot Replicator 2X ( I know, I know, it was the printer that was open that did 1.75) and I was only able to get 1 part to print even half way. I was getting constant nozzle jams with fair consistency. Igus recommends 200°C at the nozzle and 95C on the bed. The very first part did the best and got about 5 layers at .22mm and solid infill at 90mm/sec at these settings before the jam. After that I tried the following.
210° nozzle at 90, 50, 20, 10mm sec
205 nozzle at the same
195 nozzle at the same
All jams. Basically if the filament sits in the nozzle for any length of time hot it hardens similarly to what we have seen with PLA in the 2X. The filament is very soft so any hang ups in the nozzle it strips quickly and easily. Anyone else have more luck?
@Joe_Spanier , I’m sorry you’re running into these problems! I’ll take this information to our product managers, and see if I can get any advice to bring back to you. Feel free to shoot me an email (social@igus.com) if you have any other questions or problems!
@Joe_Spanier Here’s what I’ve dug up – Others testing the sample filament have had good results extruding at 220º instead of 200º, onto a 95º bed, and especially good results when extruding slowly. I’ve also had someone tell me that they used PVAc glue (White Craft Glue (Like Elmers) + 5 parts water), instead of kapton or perforated sheets to help the filament to stick to the bed, if that was a problem for you as well.
I hope this helps! Let me know if you run into more questions!
I printed a bunch of Tribo filament this morning. I actually had a rep from IGUS here when I was printing it. Which was interesting.
230C on the nozzle. UHU Stic on the bed, retractions just as normal at 0.8mm @ 70mm/s. It doesn’t stick quite as nicely as ABS, but what do you expect, it’s meant to be slippery! Get the first layer slow and low and you’re fine with UHU Stic.
Obviously using an E3D-v6 for all this. I did notice that the filament actually deforms very easily under pressure from the idler against the hob and that the hob teeth sink very easily into the filament, so do back off on the idler pressure a little. It’s a little brittle and delicate so make sure you’ve got some way to allow it to feed nicely off the spool.
I would say that you want to print this stuff like ABS. It’s certainly very close to ABS, it’s smells of styrene monomers when printed, it dissolves in acetone, leaving behind a certain amount of granular powder which I assume to be part of their tribo-witchcraft. The IGUS rep was tight lipped about the makeup for obvious reasons though, so this is all speculation.
@igus_Inc I look forward to hopefully reselling your filament very soon, and will probably do a little write-up/printing guide to help people on their way. Now all I want in return is some IGUS Z material in bar-stock form! Pretty please. I’ll do something impressive with it, promise.
1.75mm has a better surface area to volume ratio, so you should theoretically be able to melt more plastic per second with 1.75mm. Not tested that assertion however.
We’re just getting parts in at the moment on a day by day basis and shipping parts out as the parts come in. Most orders out the door in a few days, but some are taking about a week depending on the configuration you order. We’ll be back to solid quantities of stock and next day shipping in 2 weeks or so.
@Sanjay_Mortimer1@Shauki 3mm filament is in production, and will hopefully become available by summer’s end!!
Sanjay, as for the barstock, we don’t have barstock (as of now) available in the iglide Z material. I just asked out product manager, and she says that the iglide T500 material is the closest option available. I’m in the US offices, but if you’d like me to put you into contact with someone in your area about getting your hands on some barstock, feel free to email me at social@igus.com.
From what I was seeing yesterday on the mk7 drive roll and 1.75 I feel like tribo would standup better to quick retraction and faster printing with the wades geared extruder and a hobbed bolt with 3mm. Mostly just because there is more area to grab and more to grind through before you completely strip out. We are planning on buying 3mm when its available to print on our army of @LulzBot TAZs.
