Core One ASA Prints
Hi
I am a first time Prusa user. I received the Printer yesterday and started doing some ASA prints.
The Print Quality is not as good as what I have been seeing online before purchasing the printer and I wanted to know if this was a setting issue when using the slicer, as my previous Dremel Printer was giving better prints and I have seen reviews that the Prusa Core One was better.
Attaching images of the Print and the Settings
Print Setting: 0.25mm Structural
Filament: Prusament ASA
Printer: Prusa CORE One HF0.4 nozzle
Supports; Everywhere
Infill: 100%
The print is happening in different directions and basically creating a parting line. The overall quality is also lacking, so I would like to know what can be done to improve the print.
RE: Core One ASA Prints
I am a bit confused. Are we looking at multiple, assembled parts here? For the "wheel" in the center, the bottom layer seems to be facing up, but for the other structures, are we seeing the top layer?
I can't provide very specific advice since I have not tried ASA on the Core One yet, but in general it looks to me like there is strong under-extrusion. Is the nozzle partially clogged maybe? In case you are not using actual Prusa filament -- did you check that the temperature settings for the material you got match the Prusament ASA values you sliced and printed with?
RE: Core One ASA Prints
Are we perhaps looking at the underside, after the supports have been removed? The parting in the middle suggests there might be a very slight tilt in the model, such that half of the first layer after the supports prints with one layer and the rest with the next layer.

I agree regarding a tilted surface as the reason for the split line -- great catch! If you look in the area of the grille (?) on the left, there clearly seems to be an extra layer in the bottom half which ends near the middle of the part.
You might be right regarding the underside of the print too. In which case I wonder, why print it in this orientation? The other side seems to be much flatter and hence the natural candidate for being printed as the bottom layer.
Even if most of what we are looking at was printed "floating" on a support layer, it still looks under-extruded to me. The next layer, where it can be seen through gaps in the topmost layer, looks equally airy, right?

So these are multiple pictures of the same part. This is the bottom side after the supports are removed. I am using the Prusament ASA Filament purchased from Prusa itself, also this was the first print done after printing the sample piece.

Yes. This is the underside after the supports have been removed. The finish across the underside is different at multiple points. As for the parting, that was not there when I printed the same model with the Dremel. Could it be a problem when using the slicer?
RE: Core One ASA Prints
I agree about printing it the other way up, if we are indeed looking at the underside. From the shadows it does appear that the face that it's currently sitting on would be the better face to print face down. As for the layer that we can see through the gaps (e.g. in the segments in the central circular piece), I suspect the very first layer is the first layer of more supports which haven't yet been removed, making the layer we can see though the gaps the first layer after the supports. That layer's appearance is consistent with the other layers we can see. The first supported layer often looks like this unless you can use a different material for supports, e.g. PLA, and hence adjust the support settings, e.g. top contact Z distance = 0, interface pattern spacing = 0.
Please save your project as a .3mf file:
Slice your file - we don't need the .gcode file but instead -
Files > Save Project as
Zip the .3mf and post it here. It will contain both your part and your settings for us to diagnose.
Cheerio,

The other face up is required to be smooth as this is meant to be a base plate. Would printing it the other way around help with both sides being printed smooth?
As for the tilt, I have not had this problem printing before. Would it be something caused when orienting the part before slicing?

Cheerio,
Unfortunately, I cannot share the 3mf file. I am an employee at a company and am Printing these parts for them. I do not have permission to share the 3mf files. I can share a screenshot of the settings if that would help.

Yes - if the other face (the one that it's resting on in your photos) is meant to be smooth then it would be much better to print that face down. It'll take the texture of the build sheet, which will likely be better than if you printed it as the top layer. Plus, the surfaces that we can see in your photos will all then be top layers, so much better than being the first layer after supports.
In your slicer (Prusaslicer?) there is a tool ('Place on face') to pick the face that will be against the build sheet. Did you use that tool to orient the part that we see in your photos? If you now use it to place the model on the top surface of the base plate that will guarantee that there's no tilt.
I do not have permission to share the 3mf files.
Understood. Try printing something that you *can* share and, if that fails, let us take a look at the file.

Not much use without the part.
To explain the discussion above:
There appears to be a very slight angle with the horizontal causing the stepping - this might be a misalignment in the slicer, it might be a badly designed part, or, just possible if you've been messing extensively with the settings it might be a misapplied support setting. The .3mf would have told us. It might also be a physically damaged printer, unlikely, we would only have explored this if the file was good.
(Some of) the poor surface might be due to a too-small support interface gap - again the .3mf would tell.
Or it might be due to a new user making unwarranted assumptions or misinterpreting a setting ...
So: Pictures, top and bottom of a print you can share together with a zipped .3mf file gives the best chance of a quick diagnosis.
Cheerio,
