a. Print removal and post-processing
This section covers the following post-processing questions:
How do I get the finished part off the print bed?
I can't get the finished part off the bed
The part has left marks on the bed, what can I do about it?
How do I remove the raft from the model?
Is it safe to paint the part when it is finished?
How can I smooth the part when it is finished?
If I have support material on my part how do I remove it?
Break-away
Dissolvable support material
How do I get the finished part off the print bed?
Use the scaper tool. Slide it along the bed toawrds the model so that it strikes the bottom of the raft. A few strikes should be enough to remove the
model (complete with its raft), though this varies depending on the geometry of the model. The bed must be totally clear of plastic debris before the
next print.
I can't get the finished part off the bed
If the part is stubborn to come of the bed, it is much easier to deal with removal by taking the print surface out of the machine, and striking the raft
from a downward angle.
If a part is very difficult to remove, persist with the scraper. Tough removal is because the nozzle was referenced at an incorrect height to the nozzle
- i.e. it was too low when it started printing the first layer. Refer to the manual to ensure that the nozzle is correctly referenced before the next print.
