PLEASE HELP (scale model of the equipment)

[DavidXpat]

Hello everyone,

i am very new at 3D printing! so please keep this in mind. i have a STP file of a peace of equipment and all i want to do is scale it down print the outside. but when i try to print it treys to print all the insides and the housing get to thin and collapsing. Is there a way of making the entire thing a solid with nothing internal. All i am trying to do is make a scale model of the equipment. PLEASE HELP!!

you most likely need to fill it in with a cad program.

Any slicer will see the model and while you can do 100% infill, that won't get rid of the actual modelled spaces.

The other way is to create some basic solid shapes and merge them with the model in the slicer to fill in the gaps.
That's probably the easiest way, though depends how good you are with your cad package I suppose.

Yeah CA is correct. You need a CAD program to do this. PM me your email address and I'll have a look at it it.
