Yeah that did come out great! I like the design too!|
I tried dying white strong and flexible black with Rit dye and it came out dark purple. Yours looks pure black!
As for depowdering on an industrial scale Shapeways should look into neutralizing electrostatic attraction.
I prefer to know nothing about everything rather than everything about nothing.

|Re: Are there volume discounts? [message #85907 is a reply to message #85905 ] Fri, 07 March 2014 02:06 UTC
There is a discount for the white and colored nylon processes (strong and flexible). For bounding box densities greater than 10% you get a 50% discount for material beyond 20 cm^3. Unfortunately this would only work for multiple parts in one design file, and would rely on you selling the parts via Ebay or in person to realize any additional profits resulting from the discount. Sometimes I put multiple parts into one file to save on development and design verification costs.|
Details on pricing
We also offer a volume and density discount on Strong & Flexible materials. For models that have greater than 10% density (material volume divided by bounding box volume), volume above the first 20cm3 is calculated with a 50% discount.
Bounding box pricing on big low density products
Large, extremely low density models printed in White Strong & Flexible are priced based on bounding box volume rather than material volume. For models with a bounding box over 10,000cm3 and a density less than or equal to 2.6%, the price is $.0385 per bounding box cm3 plus a base price of $1.50. See our blog post to learn more.

|Wall Thickness FIXING starts now! And you thought WT visualization was good... [message #85912] Fri, 07 March 2014 03:45 UTC
Today, the whole team is excited to announce:|
WALL THICKNESS FIXING!!!
Yup, not only do we let you see thin walls, we now give you a way to fix them --- with one button click!
Wall Thickness Fixing is an add-on to the Wall Thickness Visualization tool that thickens them to the minimum recommended wall thickness for the material you're working with. You can click 'Save and Exit' to apply your fixes or Download the fixed model files for use in your 3D Modeling software.
Here's an example of a model fixed with Wall Thickness Fixing:
How to use Wall Thickness Fixing
Are you drooling over those screenshots? Here's how you can start fixing your models:
1. Upload a model to Shapeways or view the existing Model Edit page.
2. Look for any materials that have a 'View Thin Walls' warning (this can take a few minutes)
3. Click on the 'View Thin Walls' link
4. Click 'Fix Thin Walls' to generate the proposed fix geometry (this can take a few minutes)
5. Preview the proposed changes highlighted in blue
6. Choose one of three options:
Save the Fixes - We will update your model to match the proposed fix geometry and re-run our model processing to make sure the model still passes all of our other checks.
Download Fixed Geometry - You may want to adjust the fixed geometry or only apply some of the changes. In this case, we've provided you with a .zip containing three files:
1. Your Original model (model_name-original.stl)
2. The fixed model (model_name-fixed.x3d)
3. The 'delta' geometry (model_name-delta.x3d)
The third file (Delta Geometry) contains only the newly generated fixed geometry. Think of this as the 'glue' we've generated to thicken your model. This allows you to choose how you apply the fixes to your model within your modeling software.
Cancel - Don't worry, we haven't modified your model. Clicking 'cancel' will take you back to your model without making any changes. You can always go back and view or download your fixed geometry at a later time.
Tried it? Tell us what you think!
Every model is unique and we want to work with you to improve our Wall Thickness Fixing tool. Please share your feedback, successful fixes, or problems right here. We'd love to hear from you!
If you haven't noticed, we've been spending much of our time building better tools and processes to help you design models that will withstand the manufacturing process. Here's a quick look at other projects we have on the table to improve printability:
1. Calibrating the checking process - Currently a person checks every model that comes in to ensure that it meets our design guidelines and thus should be manufacturable. We're now comparing results across different checkers to ensure that our 3D Printing Engineers are consistent in how they locate and find problems.
2. Giving you more transparency into what's happening with your order - We're starting to surface more information about what's going on with your design and how it handles each step of the manufacturing process, from printer to post-processing, to shipment.
3. Building better automated tools - Wall Thickness Visualization and Fixing are just the start of more automated tools to help you find structural problems with your models as quickly as possible.
Although we've thoroughly tested this tool both internally and with our awesome beta testers, we know that there's room for improvement. Here are a few issues you might run into:
1. The Wall Thickness Fixing 3D View shows a preview of what the Fixed model will look like using voxels. We render the preview at a slightly lower quality than the actual model so you may see some small unexpected artifacts. These are merely visual issues. You can verify what the actual model we will send to the printer will look like by loading the 'fixed' mesh in your 3D Modeling software.
2. The software that generates the Wall Thickness Viz is currently using a slightly different algorithm than Wall Thickness Fixing. As a result, you may see some small yellow (warning) spaces after running your fix. We're currently working on improving our Wall Thickness Viz software to line up more accurately with Wall Thickness Fixing.
3. Wall Thickness Fixing works better for more organic or curved geometry. Because we thicken using small spheres and curved surfaces, it does not work as well for flat or angular shapes.
4. Although we can thicken the walls with our Wall Thickness Fixing tool, you may run into other problems when a 3D Printing Engineer checks your model. For example, this tool does not detect or fix Thin Wires, Loose Shells, or any of the other common problems we run into when manufacturing models.
All that said, PLEASE let us know what you think!! And, Thank you to our awesome Beta testers for all your help in developing this tool :-)
