Assembly Procedure
Step 1: Printing
...
Align first specimen in a corner with the longer side of the specimen touching the shorter side of the curing fixture.
Wedge a support fixture along the specimen to hold the individual pieces in place. Correct placement shown in fig. 5.
Figure 5: The adhesive specimen is shown in blue. The support material is coloured in orange and labelled. They hold pieces on the same level in place.
Place three support pieces perpendicular to the first specimen at each joint to provide support for the next one (fig. 6). Continue placing specimens down until the tray is full or until you are satisfied with the number of specimens. If the tray is not full, wrap a flat piece of wood in saran wrap and place it flat against the last specimen. Put a weight behind the piece for support (i.e. a piece of steel, a block of MDF, a rock, etc.)
Figure 6: Two specimens (blue) with support pieces (red) restraining movement at each joint.
Place a flat board on top of the tray and specimens. The flat board should also be wrapped in saran wrap. Place a weight on top of the board.
