Tolerances Between Objects
Hi guys,
Just wondering how you deal with tolerances between objects in the modeling phase for stuff like box walls.
I'm modeling out a master for casting in urethane resin of a steampunk prop with around 17 individual parts. I've separated the parts for ease of casting, and hopefully ease of printing too.
When I started modeling, I snapped to the grid when creating my surfaces, but after I'd done most of the work, I realized that although many parts will be printed separately, I didn't leave any space between them so the printed parts will have no tolerances and probably not fit together properly.
I'm not expecting to print this on a pro SLA machine, so I'm wondering what you guys think - Do I need to go back and modify my object walls by 0.1~0.01 mm so they'll fit together, or is the accuracy of most desktop machines like the Replicator 2 or Ultimaker such that I needn't worry about adding tolerances?
Piccys for reference:
This is the issue: No gap between walls in spots in my model: Attachment 1293
For fun, this is what the final prop will look like: Attachment 1294
This is a breakaway pose of all the proposed components. Attachment 1295
Some stuff is shown that won't be 3D printed, like the vacuum tubes (which I'm casting in clear resin) and the electronic components.
