I have a model of a 1.45 liter cup, how do i calculate it to be a 0.6 liter cup?

lets just say that it wasn’t just my history teacher that cried 😂

In Fusion360 there is a function to calculate the volume (of water).

I guess I wasn’t clear enough.

-If I have a model of a cup that holds 1.45L and I wish to resize it in Cura so that it prints a cup holding 0.6L ; how do I make that calculation? (By hand of course)

Roughly scale with 0,745 , or more exact, sqrt3 (0,6/1,45)

"Tredje roten ur..." in our language 😉

See, thats the problem, can't even recalling ever heard 'tredje roten ur' 😄 Men alltid kul att läsa lite svenska...

I guess I'm out of my league here, but is that (sqrt3 (0,6/1,45)) the actual formula. I'm mostly thinking of of that 'sqrt3' thingie. Or is this solvable with just multiplying and/or dividing?

*I guess I don't make a lot of sense due to my ignorance. I looked at my calculator and found that sqrt3 function and managed to get the result you gave me so hopefully I can remember this.

Thank you Anders!

sqrt3 is a bit of a strange name: Whereas sqrt is short for square root, sqrt3 is actually the cube root.

Square root of a value is the inverse function of square of a value: sqrt(value * value) = value.

Cube root of a value is the inverse function of the cube of a value: sqrt3(value * value * value) = value.

Newbie tutorial (written with myself in mind):

On your calculator type in the following:

0.6

/

1.45

And now press button marked in image below

I didnt know the phrase in english so thanks for the lesson.

(Even though math are considered to be the common language of the universe 😄)

Cube root what was I was looking for, hence writing it in our native language too...

• The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.

So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.

The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.

The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

• Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm

We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
