how does mini do it?

Post by rogerw » Sun Oct 27, 2013 7:16 am

how does the printer 'print' to let you separate your part from the support material?
is the support material printed thinner or left to dry a split second longer ?
all seems to print the same to me but somehow you can peal the two apart.

The simple answer is, the "raft" and "support" are laid down first then the "part" material is placed then the next layer is started with the "oldest" area of "support/raft" is then covered with part material, this allowed the "support" to cool more thus not create as strong a bond.
If you watch carefully you will see each layer is always created in the same order.
First layer:
1. raft
2. support
3. part
second layer:
1. raft
2. support
3. part
repeat.....

As drew says there seems to be some cooling allowed and there is also a change in layer heights so the part layers aren't pushed into the support layers like they are with a normal layer. But exactly what happens is the secret sauce to commercial printers that everyone in the Open source community would love to know.

so letting the support layer cool and maybe adjusting the layer height so not pushed into support - yep that makes sense - thank you gents.

Nophead, one of the more respected characters contributing to the reprap project guessed at the process here (after observing an Up) http://hydraraptor.blogspot.com.au/2012 ... pport.html
