Pre-purchase question - Splitting

<p>Hi.</p><p>The job I have is to print out plaster mould masters. These are 24” by 18”. (I understand that there may be alignment issues but they can be fixed in post-processing). </p><p>I don’t know how or what software will handle this?</p><p>It will have to segment the print into 3 wide by 4 high (at 6” x 6”). I guess the prints would be best with a Raft, so how does this work? Do I tell it what size I want, it add the Raft and send it to the printer? What if something goes wrong with one of the segments fails in printing, etc, etc. </p><p>Many questions. Difficult to get answers. </p>
