Achieving solid object

I am trying to understand how to print a solid object on my i3. I have a .stl file which  works very well on  my SL1 to make small pcb supports. However when I slice it for the i3 I have just made I don't get a solid object, and the base is far from solid.

RE: Achieving solid object

Im afraid we need far more details than that to provide any help.  The best way is to get it as you are slicing it on Prusa Slicer, then use File>Save Project As.  This will save a .3mf file to your computer.  A 3mf project file is a snapshot of the model(s), the plater positioning, any modifiers etc and the in use profiles.  Its basically a snapshot and allows others to slice with exactly the same settings.

Then take that 3mf file and ZIP it up and attach it to a reply here.  Must be zipped or the forum wont accept the file.  With that project we can provide much more help.

Thank you for your reply. I have attached a zipped version of the .3MF file as requested.

The object I am trying to print is small (very small?) but it prints very well on my SL1. The advantage to me of using the i3 is that I can print larger numbers in one run. The holes in the base and the spigot are meant to be through holes. Using the SL1 only the hole in the base gies all the way through. However the hole in the spigot (1.7mm diameter) is only partway through. But this can easily be drilled through in a 'post production' process. The idea is that will be tapped M2 to secure the pcb to the bracket. That is way I need a 'solid' object to allow the strength to tapp and ten take the screw. Again this works OK using the resin printer.

The Slicer for the i3 is way more complex than for the SL1  and I can't understand yet the links between adjusting a paramter and the effect on the printed part. 

As you can guess I am a complete novice at this stuff so any guidance / hints etc  much appreciated.

I should have added that the i3 is a just completed kit. It has gone through calibration OK - as far as I can tell. I have printed the 'frog' on the included files and that is superb so I hope that tells me that the calibration and setup is in the right ballpark.

RE:

It looks like you had your model at a slight angle instead of flat against the bed.  When I did a 'Place on Face' operation, they sliced with a solid bottom. See https://help.prusa3d.com/en/article/place-on-face-tool_1781

I have both an SL1S and an MK3S+. Slicing for filament is way more complex.

Thank you for the reply. When I sent the .3mF file I did slice the file anew as I had deleted the previous code as it was such a failure. When the slicer opened the object it was upside down. In my haste to get the  file for the forum I didn't take care to ensure that it was sitting flat. I will try again.

I totally agree with  your view of the slicing 'process' for the filament vs resin. I don't understand the resin slicing BUT I have had quite a few successful prints. Using the i3, I have no idea how to approach it.

At my advanced years - way past retirement - it takes a lot longer to learn 'new tricks' especially when they are explained / surrounded by a new vocabulary! Still its good to learn!

RE: Achieving solid object

For most of your printing, the default settings for filament printing will do just fine. Happy Printing!
