Printing tip of a pyramid

Recommended Posts

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?)

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,....

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
