That one would be too expensive, their extra "multiple object file" fee taking it over the $30 limit.

Can't see where they clearly specified that limitation upfront for the majority who haven't designed their own STLs (while cases have to come as some incarnation of Yin&Yang to "embrace" anything).
Then again, sounds like realigning the halves in the file (so the recipient has to separate them after fabbing), faire un pont et ça ira?  ???
I would not take the risk of adding a bridge (well, at least 2 or 3) without testing it before. It need to be strong enough for the manufaturing and post process, and weak enough for the user to break it without damage.

@Gerald, maybe http://meltwerk.com ("best price guaranteed" SLS in spite of its name) rejects your file for the same (unspecified) reason, would "building a bridge (to be broken) to their heart" (All3DP.com's campaign logo after all) do the trick?
One that serves a justifiable technical purpose such as ensuring coherent orientation/size/surface structure (as had been genuine issues in earlier tests) of course (rather than subverting unfortunate constraints of their own contracts with printing services).
The attached ZIP contains 2 files, one for each pieces.
Note that  http://meltwerk.com recommend at least 7mm depth for then embossing, the one on the cartridge design is only 4mm.

There's no better time coming for that than when SLS is at a dollar incl. shipping... ;D (and you've got an army of testers whose FDMs melted out of proportion)

BTW: The bridge might be one that breaks by rotation (twisting) too. I.e linking & growing the halves a centimeter apart (or much less since the PLA powder will always fall out anyway) in a "TIE fighter" style configuration.

Looks like the experts are actually here....  ;)  Sorry for derailing, but I would need 100 pieces of regular Cartridge cases for a good price (means quality is more important than money, but not too expensive either). Any advice which producer could be the best choice???  :)

I didn't get why not to go with a "bridged 2 in 1 design"? Brilliant idea!

I don't think 3D printing gets cheaper with volume really, because it still takes a long time to make each part and most of what you're paying for is machine time not raw materials. I might be wrong though (more info welcome from someone that knows more). But I think you need something else, maybe someone can suggest something. The only thing that comes to mind is injection moulding, but that costs thousands to create the moulds (and then pennies to create each part) so only makes sense if you're making really huge volumes.

If we only could get the original molds...

Something for beta testers :

Great job Gerald!  8) <- The Force is strong in this one!  :D
Saving $27.68 on "Solid white polyamide, dyed velvety soft surface Black" @ i.materialise.
After yet another XSS alert, this time All3DP.com even went back to a "paypalsuccess" page saying "Thank you for ordering!" (and then nothing else).
One could also get it polished - or (even dyed) Alumide if electrically insulating all contact points with the board well (metal particles in PLA, so that's probably for other projects though nice; unless conductivity is ruled out).

Munchausen

Great! I have also ordered one. Unfortunately I had to get a raw white one because i.materialise wouldn't deliver to the UK, and that was the only option from the other producers that was <$30. It is weird because they do normally deliver to the UK. It said "There are no delivery options available please review country and state/region" or something like that.

Octoate

Did you already receive the confirmation that the new design will be printed?

Not sure Alumide is a good idea, aside electrical isolation, the material is weaker. Sculpteo did not validate the model on this material.

Do you think that will hold? The upper surface doesn't seem to have enough support. Can the lid not be flipped over beside the bottom shell and connected with breakpoints?

Would be the other option, but it won't need much support: being made from SLS powder, not FDM filament (though heat might still be an issue).

I just expect it's strong enough for manipulation, weak enough so you can break it.
Having the two part beside and connected mean that the breaks will be visible. Here they are inside.

That's what I mean. I could imagine problems with sagging on the top surface.

The model is for SLS printing only.
It will be fully buried in powder during the manufacturing so there will not be any more sagging than if it was two separated pieces.

Thanks to @gerald we once again are taking our chances.. Let's wait and see what happens :)
(I switched to yellow+velvet this time :P )
M'enfin!

Yes, I know the SLS process well, there's a massive SLS machine in the office next to me right now (which seems to print more or less 24 hours a day). However, despite being buried in powder, large suspended flat thin surfaces can still sag sometimes if you don't get the settings exactly right.

I placed my order on their site for $ 1.. except the paypal confirmation nothing else for now .. strange  :( let's see if the miracle happens ..
Solid polyamide, dyed velvety soft surface PINK  ;D @ i.materialise.
They are from Germany.. but i don't think they made it themselves.. just placing orders for companys..

dodogildo

I got my confirmation message at the long last. But the following line was included in the message :)  ->

"thanks for your order and for your efforts. We hope, that this single object file will be printable!"

Haha, indeed.
M'enfin!

I have already my confirmation email for the order  ;) by someone named Mathias Plica..
he asking me about the correct adress for the shipment ..

Description:
C4CPC_OnePiece.stl (Polyamide, Dyed, velvet, Pink)

it looks like positive for the moment.. ;D

hsimpson

Thank you @gerald for your work. I ordered the black velvet version. I got a preliminary confirmation. Unfortunately, the PayPal transfer has not yet been received :(.

Mathias

Hello all,
this is Mathias from All3DP. Please allow, that I post here in your dedicated forum.
Some of you have ordered the C4CPC 3D printed cartridge at our service of All3DP.com.
First: thanks a lot for your trust and for ordering at our service.
Our promotional offer (print for 1$) is serious and we do this to promote our service, which is a new offering.


Those of you who ordered at our service, have noticed, that printing multiple part objects is not accepted by our partnering 3D printing services (Sculpteo, i.materialise) or that cost is just doubled in case of an .stl-file containing two parts (Shapeways). There are true reasons for this policy of our partners, which we understand and respect.


Now we have passed on the "one piece"-stl some of you have ordered, to our partners. I would like to inform you, that the orders are 'on hold' at i.materialise, which means, they are being checked. At Shapeways the order is in the pre-production state.
We should be very glad to deliver to you as promised and will keep you updated.
Thanks!
