Example of printing with support material

Post by dkightley »

Its not very often that I have to print something using one of the automatic features of the ReplicatorG slicing software, so I thought I'd show some pictures of one of the few times I've used it.

The part is one of the two arched end sections for the Bridge. Here's a link to a post on the Bridge thread showing the section: viewtopic.php?f=8&t=123&start=31
Support material on the extrusion process is actually thin webs of the printing material designed to break away when the printing is complete. Here's the part approx. 25% printed:

Most of what you see is support....but you can see three of the vertical columns in varying state of construction. And here's a view from the top showing the support material holding two of the three columns:

After just over 15 hours of printing, the final block of plastic emerged from the printer:

And after a slightly nerve-racking period armed with a chisel and a scalpel, I ended up with the final thing....and a pile of scrap plastic!!:

Material cost? About 30p....if that!
