I would estimate that this would have troubles when being fired. What you might do is add a center post that would support the weight of the cup while it's in the kiln.]]> stonysmith 2012-07-12T03:15:54-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=51222&th=10169#msg_51222 Youknowwho4eva 2012-07-12T13:21:20-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=51223&th=10169#msg_51223

Springs: 5mm
Cup wall thickness: 4mm

Supose I upload the edited STL file (see below) including, in a ZIP,
a ReadMe file and the image below – will Shapeways do it ?

My gut feeling is that the springs can support the cup (is quite thin!) in the green stage.

I am going to order it soon; I'll keep everybody posted with the results.

And the answer was:
"For your reference, the following models have been rejected by our production team:
- Sake Spring Cup #1 in Glazed Ceramics: Can not be printed
: spiral will not support cup and will slump during firing "

I liked your idea of turning the model upside down, but I don't like too much playing Russian roulette with my money.
Suppose I do what you've suggested, then they don't bother to turn it upside down before glazing
It would be very nice if Shapeways would provide for a Designer's Note in the upload window.


On August 9, I used the coupon to order
"Drink to Your DNA!" - Espresso & Sake Tower Cup – that seemingly could have the same "slumping" problem.

On August 14, a customer bought the same model from my shop.
Since, in this instance, "no news" is "good news", I still keep my fingers crossed

Thanks again for your excellent advice.

Hi Ralph, Maartje, Kevin, Christel, Joost, Michon, Mitchell and Gary,

Please see my post "Will this print?" in the forums
http://www.shapeways.com/forum/index.php?t=msg&th=10169& amp; amp; amp; amp; amp;start=0&
It generated quite a lot of interest from your readers.

I would very much love to have this printed.

Please see 2 proposed solutions, and let me know if feasible.

1. Proposed by opresco (see self-explanatory images in one of my forum replies):
I think I have a solution!
And it could work with lots of other, otherwise non-printable,
designs in Ceramics – that seem to have the same problem.
Suppose I upload the edited STL file (see below) including, in a ZIP,
a ReadMe file and the image below – will Shapeways do it ?

2. Cleverly proposed by bluelinegecko
"I would think that they could fire the cup upside down initially, so that the springs wouldn't have to support the weight of the cup. That should solve the issue as the springs probably wouldn't compress much under their own weight. Then shapeways could fire it with the springs on bottom when they glaze it. I'd give it a shot as is if I were you."

Thanks,
Ovidiu

P.S. And, as I mentioned in one of my replies, I think it would be very helpful if Shapeways would provide for a "Designer's Note to the Production Team" in the Model Upload window.

Hey Ovidiu,
I spoke to my supply chain colleague that works with our ceramics manufacturer.
Your proposed solution of the break-off central support isn't unthinkable and could possibly work.
So while I can't guarantee that it will work, the only way to know for certain would be to go ahead
and place an order for the model.
This way it can go through all the necessary checks for printability.
Regards,
Gary

Just placed the order for the revised model incorporating the "break-off before glazing central support".

"order will be shipped on or before September 5th "

Bad News:
-------------------------------------
"Hi Ovidiu,

We're really sorry to let you know that there was a problem with your recent order. These design(s) could not be 3D printed in the material selected:

Sake Spring Cup #1 in Glazed Ceramics
Reason: Can not be printed
Additional information: This piece will not print, the center "leg" is tapered at the attachment point

Please take a look at the attached images for further explanation. We've highlighted a few areas that will cause issues when printing.

Given the nature of 3D printing (converting digital files into physical products), every now and then we catch designs that will be too fragile to create in certain materials. Though we do our best to defy the laws of physics and try to find these issues as early as possible, some are only found during the manufacturing process.

Sorry for the inconvenience.

Your continued satisfaction is our top priority, so if there's anything else we can do to help, please let us know!
Kind regards,

The Shapeways Service Team
Ralph, Maartje, Kevin, Christel, Joost, Michon, Mitchell and Gary"

So, IT WILL NOT PRINT! ]]> opresco 2012-09-05T15:31:28-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=53722&th=10169#msg_53722
If it was being made by hand, I'd guess you could make a square cup, fire it on it's side, then glaze it upright. Well, or fire it with any other type of support.

No idea if any of that is possible in this instance, as it's probably an automated service/system and changing the orientation half way through is not supported.

Oh, or cast it from metal? Or is that not food safe? ]]> TechyBen 2012-09-06T23:15:30-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=53724&th=10169#msg_53724 I've no idea why they turned it upside down, with the new break-off support and all
I guess that the cup, as is, it could be printed in Stainless Steel, but this material is not food safe.
Anyway, they concluded it is not printable in Ceramics and I am not going to waste any more time with it!

And, BTW, I just received the Glazed Ceramic print on the "Drink to Your DNA!" - Espresso & Sake Tower Cup
that was also "pushing the limits..
This one came out very nice, so I updated the page with actual pics.
