Did I forget anyone / objections? Please let me know and I'll set it straight.

ITO substrates can be bought from many different suppliers on Ebay.com, with widely varying prices. I bought mine (5 pieces) from seller "yaolihong2013" (no affiliation) because the same shop also sells Ytterbium.

The AlQ3 and TPD were both bought from TCI-chemicals (no affiliation).

The 3D-printer used for the photoresist exposures was a Phrozen Sonic Mini 4K. Avoid the new update (1.9) of the Chitubox-software supplied with this printer because it does not work properly. Version 1.8 or earlier does works correctly.

Photoresist used : AZ 4533 supplied by Microchemicals (no affiliation)
