multi part printing problem

[sirlui]

Hi everybody,

I´m rather new to 3D printing (that´s probably the most-used phrase in 3D-forums ever! ).

I get ok results with PLA already and now I´m trying to get even better results by printing the same model over and over again with different Settings.
For this I use the wellknown traffic cone, which I´ve scaled down to 50% with my 3D software (Rhino 4.0 btw)

Sice cooling seems to be an issue, I figured I print 2 of them at once, so each layer could cool for a moment on one model while the Printer is at the other model..

First I tried importing the two stl-files and combining and duplicating them..
well, since, once duplicated, they are identical, if I Combine them, they Combine at the exct same space... then dragging them apart only drags one part of it again..
Probably I´m too stupid for this and there is a way to do that. If so, please let me know...

But that´s not even the Problem:
Since I was too stupid to do it that way, I simply opened Rhino again, duplicated the model there and safed 2 new STLs with the White and orange layers at the distance from each other I figured was ok... (a few, maybe 6 cms..)

Now, opening, combining etc, no Problem..
I tried med res print and included a skirt, 1 layer high, 0 distance (so I would have to break it off and it helps sticking..) 8 lines wide...

I figured, S3D would then print layer by layer, switching back and forth from one model to the other, thus helping cooling of the layers...

What happened was, that it printed skirt and the first 3 layers of the right model and only then switched to the other...
Having endless trust in S3D I thought "ok, software knows what to do and will not collide nozzle with already printed part.."
Well, it didn´t, but what it also did not do is move back down to the printbed, but it tried to print the second part of the model at the height it was, so a bit over a Millimeter...

Anybody seen this before?
What is it I´ve done wrong?

I've done plenty of multi part prints and I definitely haven't see this issue. Are you sure you have things setup correctly?

There's a pretty good tutorial on this topic:
http://www.simplify3d.com/support/tutor ... -printing/

There's a few possibilities for what you might be doing wrong, so I would suggest reading that guide first

Hi,

Yes, I´ve read the tutorials!

But, printing a file, that has two identical objects (I´m not talking abount the White and orange rings now) isn´t really multi-part printing...

sirlui,

I print six pieces for a sliding-block puzzle. 2 of the pieces are identical. I import block1.stl, then I import block1.stl again, then block3.stl, block4.stl, block5.stl and block6.stl. Then I hit Arrange. I add my process and click (I think it's called) Apply to Models and make sure the one process applies to all six models. Then I print. I get six pieces (one entire set for a puzzle) on the bed in one "print job".

See the attached Factory file. (I think this is for MakerGear black PLA on the M2, IIRC.)

p.s.: For extra credit, print the puzzle and put it together

Good tip Dale. I didn't know how to apply one setting to multiple parts until I read your post. The "Select Models" button is on the bottom of the FFF window, right next to "Show Advanced". Now that I've set up all 6 models, I'm anxious to print the puzzle tomorrow and see how it works!
