Variable Cure Time

I understand the methods to setup a calculated mechanical motion.
Is there a way to setup a calculated cure time? For example, in Edit Profile, can I enter a formula to determine the cure time based on the layer number?

Thanks!

Re: Variable Cure Time

No we do not have such feature. Are you sure it will be useful feature?
All of resins which I have seen, have pretty restrict cure times, high values cause over-cure and less create weak structure.

Re: Variable Cure Time

With variable cure time, you can significantly increase print speed by curing layers that provide structural support for longer, and layers that don't for less time. For example, Kudo3D's Titan printer can print very fast partially due to the way they tuned the cure times in different zones. See the following link for how they recommend changing cure time in different zones to decrease overall print time: http://www.kudo3d.com/recommended-print … ing-speed/

I used to own a Titan3d printer, but I'm currently using a mUVe3d printer with nanodlp and miss this particular feature to adjust cure time which is available in their software.

Re: Variable Cure Time

Thank you for explanation.

Do we need anything other than current layer height/number to calculate correct value? Do you have any other suggestion to make it more flexible?

We could have cure time box which could contains couple of variables such as [[CurrentHeight]], [[CurrentLayer]], [[CureTime]] with ability to enter math equation. Result of calculation will be used as cure time if it is available.

Re: Variable Cure Time

I really like your idea!
In addition to the one's you suggest: [[CurrentHeight]], [[CurrentLayer]], [[CureTime]]
Here are some other possibilities:
[[LayerNumber]] (is this the same as [[Current Layer]]?)
[[TotalSolidArea]] (really nice to determine cure by expected peel force, is this in mm^2 or inches^2?)
[[LargestArea]] (really nice to determine cure by expected peel force)
[[Layer Position]]  (is this the same as [[CurrentHeight]]?)
[[Current Position]] (is this the same as [[CurrentHeight]]?)

Thanks for entertaining this feature!!
Regards

Re: Variable Cure Time

It is currently available on beta version.
Keep good suggestions coming.

Re: Variable Cure Time

Hi
Shahin you should add with diferent curing time differentz speed .
Because on the first layers vacum force is big and layer after layer this force is reduced if you can add a 4 or 5 different z speed it will be great.
