I am sure my family will soon kick me out because of all my new machines 😉
A small detour! I am am seriously starting to get interested in casting and this could become a base activity for several hobbies. When my flute is done my next projects will be (jewelry-) finger rings. After printing the sound area several times I realized that the resolution of my FDM printer is not good enough. Fine details are missing and the surface is not smooth enough. Isopropanol washing is helping but I lose some texture details to get the model smooth.
I decided to buy a resin printer! These type of printers are basically hardening liquid resin in very thin layers and are being used in various industries incl. jewelry making. The videos I watched were very impressive and it seems like this could ease my projects very much. The better the model the less headache I expect in the subsequent (metal) cleaning and post-processing of the cast.
I chose the ANYCUBIC M5s (link) which seems to be a very nice printer. I have already set it up and getting excited to print my first mouthpiece and sound area test pieces with castable resin.
Wow! This is cool. I used castable resin to print the following models. They have a perfect surface and I am now confident, that this is the right equipment and process to go on.
