Printing tip of a pyramid

[alexanderswo 1]

Hi togehter,

I have a problem with printing the tip of small pyramids. The last few layers always melt togehter and build a big blob. -What settings would you suggest to get this right? -I*m on a delta tower printer and use 3mm colourFabb PLA XT.

(how do I resize an attached picture?)

Thanks,

Alex

Hi Alex

First, welcome to the Ultimaker forum. Have some fun here and check out if an Ultimaker printer would be a fine addition to your delta tower.

The usual way is to lower temperature for the last layers where the print speed is small and make sure the fan(s) is/are at full throttle to cool the deposited material.

With XT it's somewhat more tricky as it will change transparency when lowering the temperature. I would maybe try it with 220°C for layers with print speed below 25mm/s.

If you use Cura, you might try the 'cool head lift' feature.

and increase layer time... there is an option in Cura...

and decrease print speed.

There is a plugin (teakatz) installed by default in your Cura where you can specify different settings when your print reaches a hight.

For example, for 10.2 mm and more: print speed 30%, new temp,....

Or print another object that is a bit higher next to it and print them at the same time so that the pyramid has time to cool down between layers. Just add a small cylinder or tower next to it.

hey folks, thanks a lot for your quick answers and help! I'll try what you suggested.

- in general, how do I post pictures in this forum?

Thanks!

Alex
