I am attempting to make a business card for 3d printing.
I think I have successfully imported and extruded a .svg from inkscape with some text. I chose this method over scripting because scripting wouldn't let me do multiple lines of text on one face in the past. I only have one line atm but plan on adding more stuff later (Whats the best way/order to do this? I want multiple lines of text in various sizes etc and maybe some parts or cuts made in freecad if I have space, to demonstrate some of what the printer can do). Right now I am happy with one line of text, so I can test it on my 3d printer and start dialling in settings etc as its going to be a challenging print.
When I try to boolean fuse or cut the text and pad I am getting odd results on some of the letters. They are a different colour in the freecad file. I suspect this is indicating some error, but I can't work out what went wrong, or why they are a different colour. The object properties are not showing a change anywhere I have looked.
I have also found that exporting the part to a .obj is resulting in mesh errors on the black letters. I have repeated the process a couple of times from scratch. Its not always the same letters but the end result always has the same problems. Some black letters which export flaws.
I have attached a freecad file with the problem, and some screenshots of the resulting .obj in my slicing program (Slic3r) One thing I found noteworthy is that the letter "h" was separated from the object when I accidentally clicked the "split" button in Slic3r. This button is normally used when a .obj or .stl has multiple parts and you want to separate them for some reason. I don't think it should have separated the "h" as it was supposed to be fused?
Moving the h in slic3r did make it easier to see the mesh flaws though, so I took a screenshot.
No doubt I am going about this task the wrong way.
I have a few ideas on ways to try and work around this problem, but thought it would be more productive and educational to seek advice first
Some things that seem fairly obvious to try are:
I think I will remove the http:// as its not really needed and then I can make the text bigger. Open to other design change suggestions.
I could probably change freecad settings to make the exported files have better resolution. The computer seems to be coping with this level of detail very well. Don't know what preferences to change though.
Maybe try doing the text in smaller chunks so it has less to compute per operation?
I'm also undecided on whether to have the words cut or extruded from the face of the card. I have a slight preference for cut into the face, but want to try both and see what prints better.
