Here is another example but with a "low density" cylinder. It is similar to the last example except 6 long gaps are cut from the wall to lower the density below 10%. As with the previous example the "cylinder" is scaled only in the x and y dimensions. Low density models now are often much more expensive than before which is why I did this analysis. Note that the major price drop is only due to the ability to fit the 40 mm ball into the central cylinder void beyond some scaled size. That does not apply to all situations so you may never be able to reduce cost by enlarging your model. Anyway, the model for this analysis looks like this:

index.php?t=getfile&id=75251&private=0

And the same curve sets as before...

index.php?t=getfile&id=75252&private=0

index.php?t=getfile&id=75253&private=0

index.php?t=getfile&id=75254&private=0

If I can't get the horse to at LEAST $200 range...so they have a 3D printer on site.

If you're talking $200 range, and you are contemplating a few of those, you are in price range of the lower cost 3D printers.
Although the horse size at ~79x241x300mm is pushing the price up. If there is a scale category next size down, there would be a large number of suitable printers in the $500 range.

In terms of large printers, this list has 5 printers big enough, from ~$900 (kit) to ~$1900 (assembled). Like this one.

For the kits, you would probably need to be handy/geeky or have a geek friend. And it is a still a little hobby-ish, not like pressing a button on a photocopier.

He may not be of the same quality, but from the looks of it, their models are fairly smooth compared to the grainy texture of SW's plastic, so this would work out much better for me.


If they print in ABS it is possible to get a smooth surface with acetone vapour, but again a handy/hobby thing.

@javelin98 Sorry, for the confusion: I was not specifically speaking about scale models, but more generally about any hollow model. I just took the horse as an example, which was perhaps not a good idea.


So many things to design, so little time...

Thanks for that.. i have tried creating a simple cube 2cm by 2cm by 2 cm. Whether I select none or select metric in blender, shapeways seems to disregard the measurements and assign it to inches, even though i select upload in mm.

I work in Blender, but I always send my file through NetFabb first before uploading to Shapeways. It's a good way to fix any problems, and when the dimensions are correct in NetFabb, they are always recognized correctly by the Shapeways uploader.

I opened the files you sent me, and your scale appears to be off by 100x. The cube that you made 2cm comes up as .2mm. So if you uploaded it as meters it should be the size you intend.

Your uploads may be switching to inches when you upload as mm because they are uploaded smaller than is possible to print. The software assumes that you uploaded in the wrong units and is incorrectly assuming inches.

With Blender you don't need NetFabb for scaling.

If you have set up the units (Metric or Imperial) in Blender, and you export with .x3d, the units will be respected by SW: in fact you will not have the option of specifying upload units at all. If you do not have the units set up in Blender, 1 Blender Unit (B.U.) is treated as 1 meter for .x3d

If you export as .stl, then whether or not you have units set up does not matter: stl files do not carry unit information. The BU values will be taken and then modified by the scale you choose on upload to SW (mm, inches, meters). If you have set up the units in Blender to be Meters, a 2cm cube will have sides length 0.02 BU - so if you choose Meters as the upload you will be correct (as Michael has said, although I'm not sure abou the maths), whereas if you choose mm, or inches you will be way off.

It is also worth noting that if you upload a file with a size that SW considers unfeasibly large or small, it will try to use the other scales, in order. I.e. if your model seems too small and it was uploaded as mm, SW will try to apply inches and then meters until it gets a valid size. If this occurs you will see a message somewhere in the poorly designed and over-cluttered Edit Model screens. See below:
index.php?t=getfile&id=75268&private=0
