CPE - Problems with printing big objects

Recommended Posts

Posted · CPE - Problems with printing big objects

Hello guys,

 

i have the following problems with the Ultimaker 3 Extended.

What works:

I printed smaller objects (L: 50 mm; W: 50 mm; H: 70 mm) without any problems.

A slightly bigger object (L: 140 mm, W: 20 mm; H: 80 mm) was also printed without problems. The printing quality and accuracy was amazing.

 

What doesn't work:

But the thing i always have to do beforehand is to move the object as far to the front as possible, because the adhesion on the back of the printing bed was not very good.
We are using the BuildTakFlexPlate System for a better adhesion and tried to level the bed to counter that problems. But still if you print a bigger object/ move the object to the rear we never have satisfying printjobs.

 

Current Settings:

The printer is enclosed in a case which should benefit maintaining the temperature. The settings are the following:

This is one print i had to stop because the printer started doing weird stuff.

This print kind of worked (i guess), there is still a lot of warping and weird differences in the texture of the object

 

What did i try?:

- Level the bed again and again

- Heating up the bed beforehand

- Turning down the overall bed temperature after the first few layers

 

 

I hope you guys can point me in the right direction :)

Thanks in advance for your answers.
