Did I read somewhere that this material can be burnt out and cast? as opposed to wax, is extreme detail more detailed than wax?

Your bracelet can`t be printed in steel not the method used by Shapeways now. You can print it only in WSF plastics / Cast metals and Aluminium Pilot metal.

Hi,

I wrote comment about similar bracelet recently. Your model has many long unsupported and very fragile elements. Please see my similar openwork bracelet http://shpws.me/Gr2H

index.php?t=getfile&id=101834&private=0

This bracelet not printable in steel (on SW) but successfully printed in gold-plated steel in China because has enough supports inside.

Panguver, do you happen to know the process your chinese supplier used - was it the same ExOne sintered steel/bronze composite, or direct metal laser sintered steel (or was it even steel, as the image you show is labeled "gold-plated brass"?)
Indeed your bracelet does not have the long unsupported stretches of tinarity's model, so should be easier to produce - let alone the noose-shaped free-hanging loop on the backside of her model that might even be problematic in wax ?

thanks for your engagement and comments!

But I still don't know where the big difference between material guidelines/auto checks on one side and manual checks on the other side come from. I need to understand what the criteria for the manual checks are so I can consider them when modelling. I know about the green state, but if the guidelines say unsupported walls up to 1mm (for a model smaller that 76mm etc.) then I stick to that. But manual check says now it needs to be 2mm.

Panuver: beautiful shop! I am no expert in printing technology but it should be pointed out somewhere (in the guidelines) that you can't do anything filigree to a certain degree in stainless steel (and a measureable definition would be extremly helpful here)

mkroeker: now I am totally confused, when you're saying even in castable wax the model would be a problem (guidelines: unsupported walls min. 0.6 mm (!)

As long as I don't understand what the process and criterias for stainless steel in the manual check are, modelling will become more of a lottery as one obivously can't rely on the guidelines and auto checks.

I don't know exactly but it not DMLS as I think.

All aspects of printability are hard to describe, but I'm surprised that Shapeways does not publish such a picture and comments:

index.php?t=getfile&id=101883&private=0

It is bit about long fragile parts of models. I have education in the field of production technology and tools (molds) and for this reason I find it easier to create a printable models.

Thank you for warm feedback on my store.

Don't ever use Comic Sans. Ever. Also, don't put your text on an angle. Expand the image and put it on the sides on an angle a normal human being would be reading it.

Secondly, you're complaining about relevant information? Sometimes it needs to be displayed twice on a page because, let's be honest, people are s-t-o-o-p-i-d and it's better to have it two locations instead of one.

People aren't being fooled about the variety of printing options available - it's the options available on that particular model as set by the designer. Sure, it could be printed in hot pink nylon - but just because the designer set it to be printed in FUD doesn't mean the customer is being tricked out of other options.

What does "What's In The Box Mean"? Really? That's a concern? It means: What will be in the box you receive if you order this product. I fail to understand the argument of how that's confusing.

Again, your concern about the date the model/page was last updated is another baffling and bizarre concern and it reads more like you just want something to complain.

No need to be aggressive. Some of us happen to disagree with shapeways' latest idea - for instance, the "what's in the box" will be even more confusing than the original layout if the image picked for it happens to show a photo of an assembled, painted or otherwise post-processed model,
the size given is meaningless for sprued kits or sets of items, and a designer might not even want to disclose whether a particular design is brand new or several years old.

Staples does have the printer in at least two of their shops.. one in NYC and one in LA.
They haven't expanded it to the entire chain yet.

Hi all!

I just made some models and uploaded to Shapeways. And, yes, I am new at this! ;)

In my 3D modelling software (TurboCad) the model look smooth and nice, but in the model view at "My Models" here at shapeways, it looks very faceted... Is this a limitation of the browser model viewer, or will the part have all these facets?
I exported the TurboCad file to OBJ.

TurboCad:

You need to turn off "phong shading" or "smooth shading". TurboCad is smoothing the surface of your model for presentation, but the underlying geometry is missing the fine details that you need for printing. I can't tell how large you wish your object to be, but it looks like you've got 32 facets around the perimeter of your model.. you need "a few more" <grin> Let's say that your item is to be 2" in diameter.. you need something closer to 1024 facets to make it smooth enough for the printer.

Some of the information here may help:

Here's a forum thread that discusses it:

Thanks for the reply, Stony! Much appreciated! Like I said, I'm new at this... Lot to learn.

I did nothing to the model, but exported it as a .stl file instead of .obj. This is how that model looks in the shape ways model preview:

http://i1280.photobucket.com/albums/a491/JorgenToll/Screen%20Shot%202015-05-25%20at%2020.54.52_zpsv343kwli.png

Looks much better, right?

I couldn't find the settings you mentioned. Guess I have to actually RTFM... ;-)

Of course, being my usual patient self, I ordered prints of the models, and then discovered the low poly count... Do you know if the updated models will make it to the print, if they're still "processing"? Or do they use the models that were uploaded at the time I made the order?

They will make a snapshot of the model file for printing when you order it - you need to cancel the order (from the orders overview screen in the avatar
menu at the top right of the page) and re-order to get the updated version printed.
BTW, could be that Turbocad has specific export options for the various file formats it supports, and that the defaults for STL happen to be different and
more appropriate for printing than what it uses for OBJ..

I see!
Some of the prints I ordered had already been approved and has been sent to production, so I can't cancel the order. I was just hoping that the parts that still is "processing" could be updated. Sent shapeways an email about it. But if it's too late, that's ok.
You live and you learn, right? ;)

I'll wait and see how the prints look before ordering new prints.

When exporting to .stl I had the choice of some settings, and a wireframe preview of the model.

I'll look for a more suitable 3D design software eventually. It's just that I already had TurboCad, and have been using it for 2D drawings for years.
3D designing is really fun though! May have to invest some more time, effort and money into this...
