Scale issue

Recommended Posts

I've been printing things using cura, usually from thingiverse but when I export STLs from cinema4d I noticed things don't I.port at the same scale. I export them in inches, which is the same unit I build my things in but when my 4" block is imported in its like 25% scale. I'm not sure how to fix this. Any idea?

Our 3D printing software doesn't work in inches, it always works in mm, as in 1 "unit" in the STL is 1mm. So that might be causing the difference in scale? Other then that, it's all in the exporting software. STL files are very simple files, they don't contain information like scaling.

I also had this problem until I realized that there are 25.4 mm in an inch. I simply scale the models up by 25.4 and they print the right size. I have been printing the Duplo to Lincoln log adapters from the free universal construction kit and scaling models is crucial for the duplo part of the adapter to fit.

Metric System Rulez!

All Openscource projects are( or atlest should be) made in metric system.

but you can have this issue with cinema4d in metric system too... its just easier to see 1:100 or 100:1.

You should set the standard import and export size values in the preferences of cinema4d to the desired scale and have correct export for your 3D Printer.. just remember this when working on a new project that shouldnt be scaled on import/export.

It's weird though. My model is supposed to be about 3" tall but if I scale it to 25.4 it's almost 6.5" tall. I'll try the export in mm and see. Been so busy with classes I haven't printed a single thing all week =(
