hi there,
so those are in all of the print and they are not nice to look at and also hard to hide even after sanding before priming the print.
Why do they get generated in first place? Is there a way to avoid them? Cant believe that the printer is capable of printing very fine details and then you have to see those random 'seams' in every single print.
cheers,
Marco
thanks for the answers Rafal! it seems like that this technology has indeed quite a few limitations, obviously I would love to keep the excellent qulity that zortrax have without having to compromise it in order to hide those seams :(
When I look at what I have printed during these 2 months I realize that perhaps for the type of work and quality I want to see in my prints this isnt indeed the right technology to use :/ And again its a shame cause you guys did a great job with your printer.
You are running V0.0.5? Have you downloaded the new version of Z-suite? Maybe the seams will look better.
If you are sanding and priming you could try using Bondo spot filler too. It's used for auto body work.
reply no thats an old screenshot...even in the newest builds is the same. To be honest Kyle I would love to spend as little time as possible on the print since as I said I want to focus my energies on the sculpting and creative part itself.
Otherwise I would be messing around with clay instead :)
and these are from yesterday failure ...on supports mostly..and warping always there making it almost impossible to line up a cut up model. (in here you can also see those seams)

Allora, siete italiano, e campagnolo!

I have the same feeling with 3d printing. At least with the technology that we can afford.
By the way, do you now D-shape? A large scale sand printer from a Pisa entrepeneur?
If I remember my open-source printing days correctly, there's always been a setting to randomize where the print head starts each layer, eliminating that seam entirely. It isn't a limitation of FDM, it's a limitation of Z-SUITE.

no I never heard of D-shape...but thanks for mentioning it. Seems interesting although quite far off they type of prints I would like to do.

Ha! thats good to know but too bad that we cant have that in the software we use with the Zortrax. Kinda feels like I am using an Apple machine...which I never liked because has never been customizable as PCs
Maybe you need more like this:

Not adictive printing.
I know I know...been looking into those for quite sometime now ;) it's quite of an investment tho! but it would be perfect for my needs :)
Seam visibility is a function of the sophistication of the toolpath generator, aka slicer - they occur where the tool changes direction. Algorithms exist for excellent seam hiding (far better than Zortrax's); Stratasys holds a patent on at least one such method, and they claim that the Up/Afinia slicer (which hides seams very well indeed) infringes.
It is possible to hide seam, but at the expense of a significant deterioration in the quality of the walls. If seam will be hide, the walls will have a lot of small holes something like missing material. Seam is inherent symptom occurring in this printing technology as well as the visible layers.
I think about add to Z-Suite option with a choice of algorithm to generate seam.
BR,
Rafal
Rafal - Please do add this! Those holes are going to be their either way. Right now they're just all lined up :)

ha! thanks for pointing that out. I hope that something can be introduced in Zsuite. I really hate to go in and try to remove that seam when the rest of the print looks great. Sometimes I have some 'texture' to the sculpture and if I go and sand off the seam then I will have a smooth part and the rest texutred...so yeah in a way or another the seam just sucks :/
But I am hopeful in Zortrax team :)
