Hi, In my last job I used Solidworks to create fixtures and tooling. It was all in-house. I would create the shape, slice it and then send it to the printer. On the printer software I could select the skin thickness - simple.
Now I'm using Fusion as a hobby and I need to send it out for printing. How do I select the skin thickness. Is it the "thicken" command?
Its not working for me. I can't select a face to assign a thickness to.
If its not the thicken command, how do I tell my print vendor what to do?
Solved! Go to Solution.

Hi,
How are you exporting the fusion file? If you export as a step or stl file then you set the thickness the same way as any
other file you 3d print. A step or stl file is the shell that the slicer is looking for and thickness settings are set on the
slicer.

I "export" as an STL file, but there is no options box. It has been a while since I last used 3D. Am I missing a process, or a plug-in?
Hi,
If you can export as an stl, this is a Stereo Lithography file. Stl is the native printing format for most 3d printers and is
used for ADDITIVE manufacturing. A STEP file is a different file format that can be used for 3d printing but is typically
used for SUBTRACTIVE manufacturing, think CNC.
There are no options to set as both files follow specific standards. In effect they are simply a skin of the outside of the
model to be created. It is the slicer that defines wall thickness, infill and other physical attributes of the 3d print. If
you have a simple cube then the slicer just "sees" the outside of that cube. You then tell the slicer to build the internal
structure of that cube so that it can be printed. All the slicer wants is a "watertight" shape and the structure goes on
the inside of that shape. The actual model you created in fusion might have structure but it is invisible to the slicer.

I still don't get it. What kind of file do I send to a 3D printing company in a way that ensures the the outside surface is the thickness I need (say - 1mm)?
Hi,
Please share the file for reply.

An STL is generally required.
If it is printed on edge, it could be printed hollow.
I think then you only need to specify how thick the shell should be.
Just ask beforehand.
Done. So, how do I send that to an online service? Am I asking completely the wrong question.
I understand that I need infill, but that does not answer the question.
The outer surface needs have a thickness. Is it 0.1mm? 2mm? auto? The export to STL function does not have a method of specifying that.
Hi,
You seem to still be misunderstanding what the stl file actually is. The stl file is the outside shape of the model. IT DOES
NOT HAVE A THICKNESS. It is just a representation of the SHAPE.
When you send the stl file to the printing service you can specify how thick you want the walls, how much infill and
all of the detail you need to create a print of the model.
The slicer software takes the stl shape and creates thickness INSIDE the shape to a thickness specified by the user.
The printing service may have default values for this or they may actually ask, it depends on who you deal with. Once
you have the inside thickness specified by the slicer you then set the infill. Again, this is a portion of the model that
is created by the SLICER software. The printing service should ask you for this information. The file you send them
is just a container of empty space that the slicer builds the printed model inside of. The printing service uses the
slicer software to make a printable model.

If you shell the solid you have an inner and an outside shape.
I sliced the shelled version of the STL.
Hi,
If you shell the surface you do indeed have inner and outer walls but the slicer still will only see walls of zero thickness
that you then tell the slicer to create when you set the wall thickness. By shelling the shape, all you have done is
effectively told the slicer that the interior volume is now between two walls of the shell instead of the interior of the
model. If you set the wall thickness to greater than the distance between the shell walls then the slicer will throw an
error because it cannot create walls thicker than the space available between the wall surfaces.
