The 3D printable mold was used to cast 4x2 blocks out of PDMS which are LEGO compatible. These blocks utilize Luminescent Solar Concentrator (LSC) dyes for colour and transparency. The mold allows for quick prototyping, replacement of parts, and ease of extraction.
To close the moldplace all the walls in the bottom of the mold and apply pressure to the longer walls until the top part engages. Secondly, apply pressure to the shorter walls until the top part engages and closes fully. Depending on sealing application and printing settings a gap between the top and bottom half may appear when fully closed. This will only affect the Z-axis dimension by a couple tenth of a millimeter.
For a successful cast the contact edges of the walls need to be sealed, either by application of PTFE tape or by glue. With glue, apply to wall side edges and bottom edge and glue to the bottom piece.
Note to user: when glueing the walls the extraction becomes signifcantly more difficult and damage to the cast may happen. With PTFE tape the walls are still removeable.
