One of the pitfalls of 3D printing is errors in the models that don't meet the requirements of the materials being used to print.
I received the below message from Shapeways today:
Hello 1958mga,After taking a closer look, we cannot print one of the models in order XXXXXX (placed on 03/01/2014).
- We've credited $7.44 to your account.
- You may be able to update and print your model based on the information below.
Model: Metropolitan Support Brace Sprue 3.5 1
- Frosted Ultra Detail (Design Guidelines)
The minimum supported wall thickness is > 0.3mm for this material. Please thicken the walls of the model.
This is for the support braces on the Met Columns:
The support isn't symmetrical if you flip it 180 degrees ... that is, it is longer than it is tall. So, in order to make a mold and eventual casting easier, I decided to make a "mirror" image of the part on a sprue (so I only have to print once):
The model on the left is the model that I made second ... and I now realize I made the thickness too thin ... 1/2" in O scale.
The fix will be easy and take about a minute ... just some pulling of the surfaces to thicken things up. Its just annoying that I have to re-upload and make a new order for this one part.
At least Shapeways was kind enough to send a picture with the problem areas so the fix will be easier.
