More separated parts in a single STL

#1

Hello,
I have to print some very small parts (a few millimeters).

These small parts are all the same and I will have to print 10 of them.

If I upload for the estimate a .STL file containing only one this parts , I find the unit price (about € 7) to be multiplied by the number of pieces (8) = about € 56.

However, if I put all the pieces (separated and equal to each other), in a single .STL file, the price is much lower (just over 10 euros).

So my question is this: is possible to put several pieces (equal and separate from each other) in a single STL, in a single order?

Thanks!

Hi,

For most of the technologies we can’t accept files containing multiple separate parts and the online price calculated for suh files is incorrect.
For printing in SLS, however, we can accept multiple parts if they’re placed in a cage or connected into a single part. You can find out more here: Grid Container

Thank you for the answer.

Where is possible to upload my 3d model in order to have a check about the feasibility of the project?

Thank you again!

You can check whether your 3D model suits the thickness requirements by going to your Uploaded Models and clicking “Analyze” on a model.
Also, after you order your 3D prints, we’ll do additional checks before sending them to production and let you know in case of any issues :wink:

Thank you for your answer.

I don’t understand the functioning of this methodology.

Let’s assume that I upload files, place an order and pay.

The automatic system does not notice that there are things that are not going well in the project.

Only after the conclusion of the order and the payment are technical difficulties discovered which make the execution of the work impossible.

What’s up?

Wouldn’t it be more normal to do this analysis before payment?

Not all issues can be detected automatically - for instance, minimal wall thickness may be perfectly OK for a small, compact part but a big spidery thing would not print as well with it (or break when it is extracted, cleaned and packed for shipping). Or a metal part may have not enough suitable positions for placing the sprues necessary for casting… If payment was not in advance, they’d get lots of customers running their earliest concepts by them for free. You’ll get a prompt refund when the order cannot be fulfilled.

Thanks for the clear and complete answer, I understand perfectly.

I would have a very small part to make, in one copy.

I uploaded a copy here, can you give me your opinion of the feasibility, considering the small size?

I thought about choosing a metal (probably the best would be high definition steel, but brass or bronze might also be fine).

The question is this: the disc that constitutes the main part of the piece is 0.4mm and would normally tell me that it can only be made with high definition steel or bronze.

However, if I also add the cylindrical feet (which will be essential for fixing the dial to the watch case), the piece becomes compatible with all materials.

I think this happens because the software is deceived by the fact that the overall height increases.

I don’t understand if the 0,5mm height limit of some materials should refer to the complete piece or to its main part (which in my case would be only the disc).

I hope I was clear.

Thanks!
