After multiple design iterations, the part was 3D-printed in clear resin. Liqcreate Clear Impact was selected for this part. As the transverse flute was too big to print in one piece, it was cut in several files. The seperate files were printed in clear impact resin. The clear parts were washed and post-cured after 3D-printing. A post-processing step was required to get to complete transparency. Polishing is an option for simple parts. For difficult and hollow printed parts like the transverse flute, a clear coating was applied. Afterwards all pieces were connected again to get to the endresult: a clear and transparent 3D-printed transverse flute!

Clear Impact

Liqcreate Clear Impact is an optically clear and transparent photopolymer for SLA and DLP technologies in the range of 385 – 405nm. Parts created with Liqcreate Clear Impact are perfectly clear, slightly flexible and have an excellent impact resistance. The high toughness of the material makes it ideal for the production of functional parts which are repeatedly exposed to stress. Low water absorption and weather resistance makes it perfect for outdoor applications.
