I just started getting into 3d printing. At first I scaled my models down to a few cm tall in blender, but found them nearly microscopic at print time. After some fiddling with netfab, it seems like 1m/1bu = 1mm in print world. Is it common practice to keep the model in bu and let the printer software scale the object? Could this be an .stl export setting I missed? Is there a way to match the two environments consistently? Thanks!
Inside Blender, 1 Blender Unit equals 1 meter, however, when importing, the software you are using could perceive arbitrary units as being equal to something other than 1 meter.
There are a couple of ways to solve this problem:
1. Change the Scene's scale factor
To do so, go to the Properties panel, then under the Scene tab, find the Units subsection and change the Scale field.
When set to 1, 1BU = 1m, but if set to 10, 1BU = 10m; Pretty straight forward.
2. Change the exporter's scale factor
To do this, when exporting to
.stl, before hitting
Export, you can change the scale field, located on the bottom left corner.
3. Scale the object up in Blender
Hit S and the enter your scale factor/ratio, for instance
10, and the object will be 10 times bigger.
4. Scale the object up in the printing software
You figure that out.
On the right, "Scene" menu (icon has a cylinder, a sphere and a lamp) go to "units" / "unit represents" and choose your units of measure. I usually work in "millimeters". Cura slices it and scales it the way I want.
