I downloade to Shapeways an image with different measure indication:

Juliabulb z^2 Mcos mm
it becoms in real 0,3 cm
http://www.shapeways.com/model/301910/juliabulb_z_2_mcos_mm. html?gid=ug

and

Juliabulb z^2 Mcos
it becomes in real 6,9 cm
http://www.shapeways.com/model/277584/juliabulb_z_2_mcos.htm l?gid=ug

I want a measure of the printed product of 1 inch = 2,5 cm
How to handdle this?

Hi Jules,

I am not sure I understand correctly, but you uploaded the model as an STL with the "mm" unit selected for the first?

And used a different scale for the second?

If you use STL files for upload, the selection box decides what the native STL unit will be for real.

So if you model is 25.4 units long and you select mm on upload it will be 25.4 mm = 2.54 cm = 1inch.

Sometimes matters become more complicated when the used 3d software uses an own internal unit and converts things on save.

Can you give some more info?

Love your (power) Julia bulbs!
Tried those myself, but never had much luck in generating affordable and printed pieces from it.

Cheers,

Stijn

Your interpretation is correct, but that was not the question.

I want to know what is the meeasure of the origal stl file and how I have to resize it to level that the printed output is 1 inch ^3

Hoi Jules,

Ik begrijp je vraag nog niet, geloof ik Wink

De eenheden in een STL file zijn in principe dimensieloos.

Vandaar dat de eenheid gekozen moet worden tijdens de upload.

Afhankelijk van de software waarmee het gemaakt wordt kan de maat in de STL dus ook heel iets anders zijn.

mvg,

Stijn

Dag Stijn,

Ik heb bij het laden van een stl file slechts 3 mogelijkheden voor het kiezen van de dimensie: mm., inch en meter. Dat is 1 mm., 25 mm. of 1000 mm. Wat ik nu vraag is om een meer variabele schaal, zodat ik de grootte van het te printen product precies kan bepalen.

Maar misschien is dit wel in de downloadprocedure opgenomen, maar mis ik deze parameter.

Aha, ik snap hem Smile

Helaas is er op dit moment, via de upload procedure nog geen variabele schaling mogelijk.

De enige optie is dus om het model op de juiste schaal te brengen voor het uploaden.

Om problemen met afrondingsfouten te voorkomen is het bij kleine gedetailleerde modellen het handigst om de mm selectie aan te houden tijdens het uploaden.

Met het gratis meshlab is schalen bijvoorbeeld mogelijk via "normals, curvature, orientation" -> "apply transform".

Dan bovenaan "scale" selecteren.
Onder de drie waarden rechts staat een vakje "uniform" als je die aanzet hoef je alleen de X-schaal in te vullen.

Voor het eerste model zou de schaal factor dan 25.4/0.3 ~ 85 zijn.
Rest nog een druk op de knop "Apply" en het model zou dan ongeveer op 25.4 mm uit moeten komen.

Heb je hier wat aan?

Dit is wel wat ik bedoel. Ik ga eens kijken bij het gratis meshlab. Waar kan ik dat vinden?

Ik heb de software gevonden. Dank.

De factor moet zijn: 2,54/0.3 ~ 8.5

Ik ga het proberen.

for the reference of those (unfortunate) English only speakers, gentlemen.

Could you please inform us as to how this issue was resolved?

Thank you very much!


Thanks for listening,

In short, Jules was asking how to variably resize the model on upload.
But that is not yet possible on the site, so has to be done pre-upload.

I recommended Meshlab for this.
As I also did in this English thread here :
