Hi Folks,

New to 3d printing and using the following:
Makergear M3-SE
PLA
Bed 70C
Nozzle 220C
Simplify3D
No enclosure, ambient temp 22C

I've been experimenting with some small parts getting them to print exactly as I'd like. During this experimentation I was printing only one part at a time and tweaking as needed.

However, when laying out and printing multiple copies of these parts (15 parts total to be printed), I ended up with substantial shrinkage and warpage over the first few millimeters of the print on every single part.

I'm assuming this has to do with temperatures and cooling?

The 15 item run did use a skirt but no brim or raft.

I'm testing now with just 3 items and a raft (no skirt, no brim) to see how that works out. Thus far, I haven't changed any other settings.

Appreciate any advice on scaling up the number of items I can print successfully. Even if rafts work, i'm not sure if the wasted PLA makes it worth while or not and I'll have a need to do this kind of multi-small-part print fairly often.
