Black ABS get's white...

Post by jack_n » Tue Sep 01, 2015 5:41 am

Hi,

i am a new user of Up Box.

The Printer itself is amazing and the results are great.

I have only one Problem that i want to solve:

When i print with black abs the 1st Layer which is created on the raft get's white.

I assume that is because bending / breaking the Material.

Is there any Solution for this to make the parts look better?

Thank you

Joachim

You can use a heat gun to restore its black color, you just have to be careful that you don't keep the heat on it for too long or the plastic will begin to melt and deform.

One way that i have improved it is by printing without a raft and using some abs "glue". Just throw some abs that is the same colour that you are intending to print into an air tight container with some acetone. Leave it overnight and spread a thin film of it on to your build plate. The consistency should not be gummy nor should it be too thin, with as bit of practice you will get it just right. I do not use any science behind my mixtures I just throw in more abs if it is too thin or vice versa. When you remove your print there is a good chance that the tiny film would have gone a little white on the base so all you have to do it rub it with a TINY bit of acetone and it should be good to go.

Hi,

i made a test with the heat gun.

The result is very good, but for smaller parts it is not the best solution.

Printing without raft would be the Optimum, but the bed leveling is not being applied when printing without raft.

Problem solved:

Printing small objects without raft
Treating bigger objects with the heat gun

Thank you very much

How are you printing without a raft? I can't get my Up Box to do it.

In the Settings you should define "Base only" and you should choose "No Raft".

Works fine with 2.17

Do you mean setting wise or it does it but doesn't stick?

Nozzle height is VERY important when printing raftless and your bed needs to be as level as possible. You will find that the auto nozzle height detection is probably not accurate enough. You will have to set your nozzle height up yourself.
