Hi Folks,

I am a CAD newbie and am having difficulty with my first design (below). It seems to need “fixing.”

It looks okay to me, but when I upload it to a 3D printing website (as an STL file) the site says that it is “analyzing, fixing, analyzing, etc.” It is eventually uploaded and printable, but am concerned that the site says it needs “fixing.” Am considering buying a (cheap) 3D printer, but am hesitant to do so until I'm able to make a design that does need to be fix.

I did check (and fix) non-manifolds and believe that all normals are now pointing in the correct direction. Attempted to download and use NetFabb, but it appears to only be available for PCs (I only have a Mac).

Thank you very much for any thoughts on how to approach fixing, or improving, this model for the purpose of 3D printing!

Verve

Some of the online 3D print services have analysis tools that will tell you what is wrong with your model.
I have experimented with:
https://i.materialise.com
https://www.shapeways.com

Both have some guidance on what is workable.

Thank you, Britt! I'll definitely check out shapeways.com. I tried i.materialise and had not found the analysis tools, but will check it out again. Thanks again! - Verve

That being said, it would be difficult to diagnose a 3D file's problem without having access to the file. 3D Printing can be a pretty involved endeavor... there's a lot of factors involved.

If you're a newbie, then this forum is the wrong place to come... you've gotta immerse yourself in all of the 3D Printing specific information you can find. I would start on Youtube watching videos from https://www.youtube.com/user/TheMakersMuse and https://www.youtube.com/channel/UC_7aK9PpYTqt08ERh1MewlQ

If you look up "how to prepare a 3D model for printing" on google, you find amazing amounts of great information...much better information than I could give you. Just like any other skill, you'll need to do some focused training for a while...and then I'm sure things will start to make more sense.

The one bit of info I could give on this model, is that you would definitely want to position that item lying on it's back... you don't want those giant shelf overhangs filling up with tons of support material. It would be unnecessary.


Thank you, Wally! This is very helpful.
