Now I know what shell mode is for...

Post by JuliaDee » Mon Sep 02, 2013 2:03 pm

It wasn't until I printed this guy that I understood the brilliance of shell mode. It provides all the external support you need (and this sculpture needs plenty for the spikes) but none inside, saving time and plastic.

http://www.thingiverse.com/thing:139995

0.2mm layer height, "gold" ABS from 3dprintingsystems.com. internal support appears to be completely unnecessary with this model, and external was used only under the spikes and not under the jaw overhang. I recommend using "stable support" since the tips of the spikes tend to sway on thin support and may not print well (don't ask me how I know). Took about 6 hours.

EDIT: I just checked and I did in fact have "stable support" turned on. So even with that there can be problems. Maybe a smaller minimum area would help, I think I had it at 8 sq mm. Also, this was printed at 0.25mm layer height, not 0.20.

A recessed white LED aiming down and a couple of red ones in the eyes and you've got a heck of a sconce... I gotta order me some more gold filament from Bruce...

Looks really good Julia! Looks like a large print, you've got a Plus 2?

No, I have an Up and an Afinia. Filled the build area with this baby pretty well, though :-)

The Plus 2 has the identical print volume of the Plus and Afinia. Except for autolevelling it's essentially the same.

If it had a bigger build volume than the Up, I'd have one (or two!) :)

Dragon is awesome! think that same detail will be there if printed on Up Mini highest setting? Going to be working on something similar in the sense of having organic detail that needs to be shown when printed. Thanks

Thanks! I have no experience with the Mini so I can't really say. Certainly it would be a bit smaller since I used the Up's full build volume. I used 0.25mm layer height so you might pick up more detail with smaller layers.

Here's another dragon I just printed with Shell Mode, using Bend-Lay. External support removal was very challenging, but Shell Mode worked great.

Aww, Gulpy is cute! I also printed Forest Dragon, but with normal fill, not shell.

Thanks for sharing!

So, am I correct when I say shell mode prints your object as a hollow object without exterior support?

Might try it on my Mini...

Shell Mode prints without internal support, but it does do external support. If you want no support at all, you can select "base only" or whatever it's called from one of the support pop-up menus; I forget which one right now.

I found out by now; I printed the solid file of Volgarr - a videogame character (http://www.thingiverse.com/thing:155820), downsized twice by 0.5, I tried shell mode as otherwise it gave an error about no support at layer x (don't remember the exact layer ;-) ).

Like this forum a lot, but the fact that a new post or reply requires to be controlled by an admin first is somewhat annoying; the Up! Mini is my new toy so I wanna play! :lol:

Shell mode is fantastic for things that don't need to hold any loads.
Have you had any luck with 'surface'? I've only tried it once, and it looked pretty ragged.
