Type of filament used for i2 MK2S parts

Please tell me which kind of filament is used to print Prusa i2 MK2S original parts by Prusa

Answered! View the answer I have this problem too

Is this a good question?

Parts of MK2S printer are from ABS (orange ones) and PETG (black ones). Using PLA might be ok however, for parts like Extruder I won't recommend it due to high temperatures inside and PLA isn't ready for such environment.

Hi, it's PLA filament (orange or black for "original color")

Edit : i was wrong, it's "officially" ABS. But is it really matter ? print them in what you have / can / want and do the experience :)

Even for extruder or heat exposed parts?

by

Yes, there's a fan to cool down the extruder, so all exposed parts do not reach hot temperature. Everything has been seriously studied :)

Take a look at C. Burgess's comment. The link provided says that Prusa uses ABS, not PLA.

by

Actually, it does matter choosing between ABS or PLA. ABS is stronger and used for mechanical situations, like 3D printers. PLA is strong, but doesn't have the same properties for mechanical stress loads that ABS has. Yes, you can use either, however it wouldn't be recommended.

Hey,

According to Prusa Support, their print farms consist of original 3mm models using ABS filament. Settings are 0.2 NORMAL without any adjustments. Further, they say the 1.75mm (255/100) can be used to print them with great results but may take a long time.

Hi all,

So I was hoping to print some spare parts for my MK2S kit before it arrives in May, but my existing printer is not set up for ABS (no heated bed). It seems like there's debate whether or not the "official" parts from Prusa are ABS or PLA...but it seems to me that I could print parts in PLA as long as I use enough infill. Thoughts? Has anyone tried this?

Thanks!

-Andy

As it's not strongly solicited mechanical parts, i don't think that ABS or PLA change anything...

You can use either ABS or PLA, however just know that PLA is not designed for mechanical use. As for the mechanical stress that is applied to the parts, you have to think about the amount of movement a 3D printer does. There are lots of micro vibrations that will weaken PLA much quicker over time than if you use ABS, especially on the base and around the NEMA motors. Also, ABS handles much higher temperatures than PLA, so I would not recommend printing the extruder housing in PLA. If you want spare parts, you can try 3DHubs.com and someone near you could print them out in ABS. Obviously there would be a cost associated with that, but it would allow you to get the parts in ABS.

Chad, thank you for your thoughts! I had not thought about the repeated mechanical vibrations being an issue - that's a good point. If I do end up needing spare ABS parts, I'll just plan on using a service like 3DHubs. I've looked into them before, and that sounds like a good solution to provide an emergency replacement part.

I would not use PLA. PLA is too brutal.

It means, if there is any mechanical constraint, it might break.

I would rather use ABS or PETG.
