Bottom layers in small curved surfaces.

Very very good quality, except you really should print him from gold like filament, and zortrax needs to finally fix bottom printing problems clearly visible on the nose.

Printing time: 8h

Support: No

It was printed without support.

Yes, he has to be golden but I do not have gold filament. :slight_smile:

What is wrong with nose?

that looks amazing good job

Rafał actually with support also prints was bad on bottom side (layer: 0.19 mm, fan: 20%, support 30 deg, fill: solid): https://www.dropbox.com/s/kmy80db0m0yxslj/P1020162a.jpg?m=

So the problem is software (I know it’s beta), the printer is wonderful, but how long till it will be able to print bottom like everything else? For my project bottom is important.

Do bottom curved surfaces ever turn out good on other FDM printers?

I do not know how it looks with other (new gen) printers, but i think that Zortrax’a probably can still improve the bottom print quality. In particular a using support.

Someone posted a photo the other day in the shout box of a print that had issues with curves. Maybe they could make a topic in the troubleshooting section and post it again. I would think seeing different examples of the problem and giving the zortrax team the stl files would help them diagnose it.

Good question!

In the Kim’s case, nose came out pretty well. Smile just drew attention to small problems, which in this case are barely visible (small figure), but it looks worse on larger prints (like in my case).

I think Zortrax have much more potential to achieve than now :stuck_out_tongue:

Increase support angle for 60degree for example as SSYS machines then bottom should be improved, or @smile should show for me exactly this prints printed by him (not from google images) which have better bottom, some parts have curved geometry at bottom and then it can result in decreased quality but this is whole limitation of ‘FDM’ technology.

Anyway funny story that @smile pointing on the picture problems which person with model in hand don’t see - this is why I can call it once again creating of confusion and scarring of potential Zortrax owners (yep for this you got banned last time because you doing damages as non-Zortrax owner this is not place for gossips but technical support and Zortrax community).

LPD/FDM/MEM/FFF print technology have limitations, as on some pictures which you saw the bottom lines when required support or when it was printed without support and hanging in the air will always have more visible layers than layers on the other place on the model.

If you want avoid this you should buy some powder/resin printer. But I want inform you that price for printer and material can’t be compared with Zortrax price :wink: For example we paid 475$ for 1kg standard resin for Objet printer which is worth 79,000$. Powder for ZCorp printer is cost around 300-350$/1kg :wink: The second important piece of information is that (for example) powder prints required finishing process. Personally I really like LPD/FDM/MEM/FFF because this is the most pure printing technology, after printing you need just remove model from the platform :slight_smile:

In summary, I see no point in writing about the fact that Zortrax must improve the software, because it will not change anything, it is a limitation, software don’t change the laws of physics.

@VipeR - I think you used not enought support in your print.

Cheers,

Mike

Here are photos the bottoms of some parts printed by me on the Up long ago, before I had temperature control or printer enclosure. In some cases they would have been better with more support, but these are pretty typical.

The Up is not perfect, but imo it generally does noticeably better in this area than the current Zortrax software. We all know that the Zortrax hardware is superior, so it is just a matter of the smart people at Zortrax accepting that it can be better and improving the software algorithms :slight_smile:

@Julia for my opinion the best way will be compare same prints from both printers and using same materials :0 I’ll print some models on UP and Zortrax :slight_smile:

BTW: I think we should move on General topic :slight_smile:

You are correct, but I don’t think it is our job to do this testing; Zortrax claims to be the best printer, so they should do the comparison testing in order to back up their claims instead of saying it is a limitation of the technology that cannot be improved, especially when some of their most loyal and knowledgeable users point out a potential area for improvement.

Here was only me so I don’t see ‘they’ as Zortrax team.

“Increase support angle for 60degree for example as SSYS machines then bottom should be improved, some parts have curved geometry at bottom and then it can result in decreased quality but this is kind of limitation of ‘FDM’ technology.”

Exist ways to improve this but just now I prefer to call it limitation than as some users try to called it in this thread as software bug I prefer to not promise that we are able to break physics but of course always exist room to improvements :slight_smile:

Best Regards

Martin, you know I love you guys and the printer. But it drives me crazy to tell everyone how great Zortrax is and then they see the underside of some curved prints and say “omg that is terrible”. These are fairly experienced users so they understand the limitations of FDM and they know what is expected reasonable quality.

I am not complaining, because I know it is early and still beta. As long as you acknowledge the areas that need improvement and assure us that you are working on them I’m happy, but I don’t like to hear denial and excuses as if there is no issue and all printers have the same quality, because that is not true, as you will see if you take your Ups out of their dusty closet :slight_smile:

Thank you Marcin that you have accepted that there is room for improvement :slight_smile:

Still you (Zortrax team) must accept that we know it is still beta software/firmware and we want only to point what we expect to improve :slight_smile: There is no place for getting angry or offended. We (your customers) just want that Zortax printer was the best :slight_smile:

Is increasing the amount of support on something change? In my case the whole area where you can see an imperfect printing was covered by the support. Is increasing the amount of support will change a plane of support on which it is model printed? I doubt it, but I could be wrong (i can’t find any info about what is changing with different amount of support).
